The Starlet Home builder's Tools and Stuff
By David W.S. King
Ask five builders what tools they think you should get for
your project and if they don't give you at least ten answers then
your not talking to the right bunch. The thing is most of the
time what they will tell you to get for tools will probably be
right for someone. However not everyone builds fine furniture
as a hobby or puts a roof on the neighbors house on a Saturday
because they have nothing better to do. So we need to look at
our skill's, our budget, and ambitions, basically this is going
to follow the process you took to choose your home built. You
need to look at the part your building and then work out the various
ways to build it. If you think this looks a little long it might
be. Just remember that I've done the research for you and am trying
to make sure you get the whole picture so you can make informed
choices. I've also done the ...grimace "Oh sure I don't mind
if you borrow that... can I get you to sign this receipt, and
I need fingerprints and a blood sample........"
The Starlet can be built with a sheet of sandpaper, a hacksaw
and a bottle of glue. If you go and try build it this way let
me know and I'll be out of town when you come to visit. The Starlet
can be built this way but would you really want to? It will take
you longer to build and you won't wind up with a better airframe
than someone who cheats and uses the odd power tools.
Tools generally fall into several categories. Tools that you
can buy, beg, borrow, or steal (if you get caught don't blame
me ). When your making up your tool list you need to consider
all avenues to get the use of tools. I purchased my airframe wood
and graded it according to spec. The wood came rough cut from
the kiln in full size 2"x10" in 12 foot lengths. I sorted
and graded the wood then cut it down to rough dimension then finish
planed it to final. I had looked at buying a thickness planer
and a table saw. I also own a 1928 Olympic Star sailboat which
is all wood and was thinking I would reuse the tools on a restoration.
However the cost of the planner was over $500 and a table saw
was easily $800. What I wound up doing after looking for used
equipment, was to buy a cheapy jobber table saw $150 and take
the rough cut wood to a local cabinet maker for final planing.
I spent a couple of hours setting up the table saw so it cut straight
and making guides and have had great results. I think my total
planing cost paid out was around $28.
On metal parts I have some sheet metal tools and a gas welder
but not much else. I purchased a variable speed 16" band
saw on the cheap $135 (what else ;-]) and purchased some large
tooth blades for cutting the metal. It's worked great on both
aluminum and 4130. The only problem I've had is when I just got
it setup and my dad decided it would work pretty good to cut up
a side of beef. I'm not sure how beef fat affect glue joints but
I really didn't want to find out. And since I wasn't going to
get any steaks out of this deal, I accidentally lost the safety
key and it wouldn't work.
As far as heavy machine work such as the gear legs, I left
that to a machine shop. I looked at cutting and finishing it the
legs but wasn't satisfied with any test parts. I've heard of people
getting good results at home so you have to decide which way to
go. If your unsure I'd spend some money.
I won't mention people who tried to borrow brand new finish
saw's to cut old wood (with nails and concrete) but you should
get the idea by now. It's ok for you to beg borrow or steal tools
but NEVER let anyone touch yours ;-] Cheap or second hand tools
will perform quite well with a bit of a tune up on them. You might
get an electric drill that needs a new cord for $5 at a garage
sale, or a saw that simply needs sharpening. Once they get tuned/fixed
they work just as well as that shiny new $150 drill. Do a bit
of research before you put your money down new or used and you'll
never regret it. Just remember the money you save now pays for
gas for flying and those $100 hamburgers on Sunday mornings.
As I mentioned there are several places to get information
about tools. One is of course other builders of the design. Usually
they will find shortcuts that save time and money. Sometimes they
find a few that take longer and cost more too, so take all advice
with a grain of salt. Other sources might be builders of similar
aircraft construction, for example the KR series of aircraft is
a glued up wood truss airframe that has some similarities to a
Starlet. You might find some information from the many on line
mail lists or web pages. I'd also check with your local EAA or
equivalent chapter to see who has built wood aircraft. If you
look around your local airport you might find lots of wood airframes
i.e. Cavaliers, Jodel's, MiniMax's, Osprey's etc. Between the
EAA and local builders you should get lots of help unless you
try and borrow tools.... The next step is to ask a few professionals
as to what they would recommend. You can ask your local airframe
mechanic but its unlikely he's touched wood airframes since leaving
school. I would go to a local cabinet maker or something similar
and ask. I'd be cautious about telling him about your airplane
until he's comfortable with the idea. If he is then I'd buy him
a cup of coffee and only then drag out some blueprints and see
what he thinks. The fellow who did the thickness planing for me
got very interested in the Starlet and both he and his son have
helped out answering how to questions since. I've had people tell
me they didn't want anything to do with an airplane because they
didn't want to get sued. That's the reason I caution you about
your approach. I've tried explaining how they were mistaken, but
found it wasn't worth the effort as they were so concerned about
this, they wouldn't be swayed by any discussion. If you run into
this then gracefully withdraw and talk to someone else. If worse
comes to worse and you can't find anyone I'd buy all of Tony Bingillis's
books and get the EAA book on wood aircraft. All of those are
worth every penny and more.
Well I've pattered on about finding information, and not letting
anyone borrow tools. So now its time to list some. What you will
find is there are three big class's of tools you will use. The
first is tools that you simply cannot do with out. These are the
tools you will use all the time and need to have at hand. The
second are tools that you will need to use a few times or have
access to. The third generally falls in the "if I ever win
the lotto..." category. Basically what happens is you have
to spend money or time on the project. You can cut the wood with
a hacksaw but a bandsaw will make short work of it. One cost $5
and the other $150. One will take many hours to cut the parts
and the other a few minutes. This is really the difficult part
of project tools, balancing the actual needs verses the desires.
My basic rule of thumb for this decision goes like this: If I
start out by saying "I need this tool so I can build this
part and that one...." I'd say I have a genuine need for
it. If I hear myself saying "if I had this I could use it
for this and that" then I really don't need it now. If I
hear myself asking" and how much for that extra part that
makes espresso?" I should go and work on my lotto numbers
some more.
Category 1 Tools These are generally small inexpensive hand
tools (which is good). And includes things such as hammers, clamps,
pencils, razor knives, rulers. It will include some consumable's
such as sandpaper's, and hacksaw blades.
Tabletop Power Tools
- These are basically small inexpensive tools. They are mainly
table top tools or jobbers tools. For example my table saw is
a jobber's saw. All of these tools can be carried by one person
and are easily stored. They do lack some of the features of the
full size equipment but they are quite capable of doing the job
and will save you quite a bit of money. They also will run on
any household outlet so no special wiring is required. The biggest
difference you will find is the table or work areas are smaller
and you can find them available in a cast top or a sheet metal
top. Stay away from the sheet tops. They can flex around and
ruin accuracy and you can't clamp things down with out extra
care. Full size will have a steel top but these small ones normally
have a cast aluminum top. This is fine for us as we aren't going
to be doing the workload expected of a bigger machine.
- BANDSAW
- Bandsaws come in a few shapes and sizes. Basically in two
styles, 2 or 3 wheel. The small table tops are generally 3 wheel
with the odd 2 wheel out there. You probably have seen both types
and wondered about the difference. The three wheel is made to
give a deeper throat so you can cut wider parts. A two wheel
would require large wheels to separate the up and down blades.
# wheels are smaller and lighter. I've heard people say the two
wheel is better but that generally seems to be a commercial application.
I think the two important things to look for in a band saw are
the guide setup and it having a variable speed setup. The guides
will make the difference between making good accurate cuts and
having a blade wonder during the cutting process (not a good
thing). The two styles of guides are either steel rubbing blocks
( or guides) and roller bearings. There is now question that
the bearing setup is far better even if its a bad one. A rubbing
block setup will work but when it goes off there isn't much warning
and your cut (and part) could be ruined. The variable speed lets
you cut different materials and get the best cut. For example
cutting Plexiglas will not use the same blade or speed and cutting
aluminum.
- BELT SANDER
- Belt sander come in two styles, handheld and bench models.
I have a handheld but not a bench. I've found I can duplicate
what the bench top does using the handheld or my table saw (with
a sanding disk). I think the handheld gives you a lot more versatility
as you can work or rework parts on the plane or else where. Then
only advantage to a benchtop model I know of is that it is better
of sanding long curves like a rib. The table and position let
you make long smooth movements. The sanding disk on the table
saw duplicates this pretty well.
- BENCH GRINDER
- I'm not sure this is an essential tool on a wood airplane.
Other than perhaps grinding the tubes for the motor mount I can't
see anything it will do that can't be done on something else.
If the Starlet was a tube and fabric machine this would change.
For shaping parts like the hinges this will come in handy but
its not the only way to do those.
- DRILL PRESS
- A drill press is one of those things you don't appreciate
until you have one. An import press will run around $100 but
will pay for itself many times over in higher quality of parts
and versatility. A table top press and most low end floor models
use a small 1/2-3/4hp motor and belt drives. They will have an
adjustable table that will probable move up and down to accommodate
large parts, and it might also tilt. It should have an adjustable
depth stop as well. The problem with small drill press's will
be the power, the size of the table, and the size of the chuck.
Again this is something you don't have to buy expensive brand
names if you check things out. I use mine for drilling and sanding
things. You can get a drum sanding kit. This looks like a baby
food jar on the end of a drill. A tube of sandpaper slides around
the drum and you then can sand parts. You can also put mill bits
in a drill press and do light machine work. A word of caution
that this can wear the bearings out but it does work as long
as you don't push it. Just as a cautionary note, you will need
an electric hand drill, but try to sty away from those drill
press fixtures. These convert a hand drill to sort of a drill
press. They work ok on small and light parts that require small
holes. But if you try and drill something heavy or hard or both
you are asking for trouble. They are not strong or stable enough
to handle big stuff. If this is all you have or will have it
can be made to work but expect it to flex or wobble and mess
up the odd hole.
- TABLE SAW
- I've only found a couple things to comment on about table
saws. Other then the cast top mentioned before you should check
the power of the motor and the measurement setup. If its used
you should also check the bearing on the blade and the fittings
and adjustments. Now to explain all this. These small table saws
use a 3/4-1/5hp motor to belt drive a 8-10" blade. The size
of the motor will determine the rate you can feed the word or
metal into the blade without bogging it down or burning. I was
lucky on the one I purchased it had a 2.5hp motor. The larger
the blade the more stable it is. 10" seems to be the average
size for these machines. Being belt driven you can replace the
motor with a larger one if needed. The biggest difference I found
from machine to machine was the way the measurement system worked.
Offhand I'd say these are fine if you want to cut some studs
for a wall but when it comes to cutting accurate parts for your
plane I'd use a ruler and measure from the blade itself. If you
setup the blade so it runs nice and true, and measure accurately
with a good steel rule from the blade even a used cheap table
saw will cut very accurately. There are lots of jigs and add-ons
for these saws. Two things you might use are a sanding disk and
a taper jig. The sanding disk is pretty much a disk of metal
with sandpaper stuck to the side. You can buy these for about
$20 or build one for less than that. (get a 10" dia chunk
of steel or alum and drill a 5/'8's hole in the middle and glue
sandpaper to it). The sanding disk lets you sand things with
a smooth long radius. The nose ribs in the wing are a breeze
to make with this setup. A taper jig is another $20 add-on and
let you make cuts at an angle. The on I purchased works on my
band saw and table saw. I used this to cut out the leading edge
spar on my tail.
- COMPRESSOR AND AIR TOOLS
- I happen to have picked up a small jobber compressor a few
years ago. This is one of those machines that once you have its
hard to work without. Other than applying coatings you won't
really use it much on a Starlet for any big jobs but it can make
life easier on lots of small ones. For example instead of brushing
on a coating over the wood frame, you can get a cheapy pot type
spray gun and spray on your sealant. There are a wide variety
of air tools you can buy to use but most just duplicate your
other power tools and won't work as well with the small compressors
most have at home. I've got more tools than this but the ones
I would reccomend are a small 1L pot type paint gun. A assortment
of blow guns to clean things off and cheat a little on cleaning
the shop. I would try to invest in a small sandblasting setup.
These are available for under $40 and you will be able to clean
off any metal parts to prep for paint etc. Depending on the size
of the compressor some tools will or won't work. Mine is on the
small size so some of the air tools such as drills don't work
as well. A random orbital disk sander can be used for finish
work as well as construction. You can sand the wood to a perfect
fit or finish. It will also help for building your cowlings etc.
A few ice ages ago I worked out at the airport to pay for
university and common practice was to use 400grit on one of these
to sand between the coats on fabric (as well as regulaur prep
work on metal etc). One thing I would like to try is a air staple
gun. These work just like the paper stapler in the office but
these staples are over an inch long. I think if you set up the
pressure so it didn't clamp too tight this might be a way to
assemblre parts such as frames. If you glue then staple instead
of clamp youcan pull the staples out after and it would be faster
than the clamps. Let's see a $80 staple gun vrs 40+ clamps..
- Air tools work but for a Starlet but they might be overkill
and money best spent elsewhere. If you have it then you will
use it, but if you don't it won't stop you from building.
Hand Power Tools
- POWER DRILL
- Power drills come in two types ones with cords and rechargeable.
If you have a good battery and don't work longer than the battery
last's the rechargeable offer a lot of flexibility. The power
seems to be close on the ones I have so they are both quite capable.
One needs to be recharged and the other I trip over the cord
or worse
- SABRE SAW (JIGSAW)
- A jig saw will let you cut out some intricate parts in metal
or wood. The problem I've always found is the cut is generally
rather rough. I only use mine to cut out parts where I can't
get into with a band saw.
Specialty Tools
- METAL BENDING BRAKE
- I purchased a 18" bench top bending brake was obtained
from Aircraft Tool and Supply (ATS) for about $40 a few years
back. It works quite well on small thin sheet. You won't be able
to bend much over 050 aluminum without a lot of work. For small
brackets and fittings under this it can make nice parts.
- POP RIVETER
- How do I love theee let me count the ways. Even on a non
metal airframe you will use one of these more than you think.
I've used mine to hold together things while they setup or to
help assemble them. An example is the exhaust system. The sections
were popped together during fitting and assembly them taken to
a shop and welded. They come in three flavors and prices. The
low end has a fixed head and has a couple of chuck sizes included.
The mid range $45 or so is a bit beefier and comes with a swivel
head fitting. This lets you pull the rivets from almost any angle,
even in very tight spots. This is very handy. The high end is
$90 and up and is the air driven pullers. Unless you have problems
with your hands or someone gives you one even the cheapy does
the same job. This really is good for a metal design where you
might have to pop a few hundred rivets to seal a wing before
the glue dries etc. I have one of the low and mid range ones.
The real cheap ones might wear out the teeth in the head after
a while but another $9 and you off and running again.
- HAND NIBBLER
- This "nibbles" through sheet metal and wood, quietly
and very neatly. You use this for cutting slots and holes etc.
in various skins and tin. I've used this for a lot of electrical
installs. I've also cut out instrument panel holes when I no
longer could remove it from the plane. "Airspeed? No it
belongs right there, in the middle where all that nice metal
is..." With a bit of care it will produce holes that require
a single pass with a file. This is the same type of as the pop
riveter in how useful and widespread its use is.
- CLECOS and CLECO pliers
- Used to temporarily hold things together, you just can't
build a metal airplane without em. Even on a Starlet they work
great for holding some of the parts together. Think of this as
a temporary reusable pop rivet. The wrench looks like a set of
slip pliers with a horseshoe the size of a quarter where the
jaw should be. The cleco itself looks like the eraser end of
a mechanical pencil. It sort of works the same way ie the plunger
gets pushed by the wrench and the jaws extend and get narrower.
When they retract again they get thich and pull on the sheet.
They can be used over and over again. They are best for assembly
work on sheet metal but you can use them for other things. If
you don't want to buy them you can simply use soft pop rivets
and drill them back out when done.
- Hand Tools
- FILES
- Hand files come in different shapes and sizes. There are
files made for metal and wood. The material is the same but the
teeth are cut differently so what works on one may not be suitable
for use on the other. A wood file will only irritate metal parts
and not really file it that well, but a metal file can be used
on wood with good results. Of course you need to make sure it
isn;t dripping in oil first but for a quick use they work well.
I found a 6 pack of files for under $10.
- These had wood handles and came in various shapes in a plastic
pouch.
- SAWS
- All hand saws woork the same but the teeth on the blades
and the handles make a big difference in what and how you cut
things.
- Most people think of the carpenters utility saw when you
mention hand saws but unless your planning on hewing out your
wood stock from a log then you probably won't need this one.
There are smaller versions of this saw that will cut and leave
a finer edge.
- These are what you want as the cut surface will be glue ready
with little or minimal work. If you are looking for these in
a store you should ask for "Finish" saws. The other
type of saw you will need is a hacksaw or tube saw. This is handy
for cutting metal and wood. With care it can cut quite accurately.
If you have a few extra dollars floating around you might want
to invest in a cut off saw. (thats not the proper name but it
escapes me right now). this saw comes in a couple of forms but
basically the saw is guided at an angle into the wood or metal.
You can buy a guide block that has fixed slots but then your
cuts are limted to only those angles. The setup I have is adjustable
over a 180° arc. It cuts metal or wood simply by changing
the blade. It looks like a oversized hacksaw blade on top of
a small table. The common uses are in home construction for cutting
moldings.
- HAMMER
- Its a big lump with a handle you wack things with. You can
actually use a couple of these and you will be suprised how much
less work it can be if you use the right one. The lumpy ends
are either steel, plastic or rubber. The steel hammer heads are
meant to drive nails, thats the simple part. Then you have to
look at the size of the material you are working with and the
nails or fasteners. If you deciede to use those little aircraft
nails to put together your ribs you need a small hammer with
a light head. Too much of a hammer will bend the nail or break
the part. It gives you more power but less control. Plastic and
rubber hammers (also refered to as mallets) have numerous uses
but generally you'll use these to hit something and not mar the
surface. For example if you are building a bulkhead frame you
might need to tap a part into place. A metal face will dent the
wood, but a rubber mallet works great. Plastic hammers are sort
of a cross between a rubber and metal head. They are harder than
the rubber ones but softer than the metal. You can also dent
wood with these but they work on metal without a problem. One
other kind of hammer that can come in handy is a deadblow hammer.
If you plan on forming metal parts such as fairing this is what
you use. they have a plastic head but have a mass inside that
when you contact something the hammer doesn't bounce.
- RULER
- You might be wondeing why I'm about to drone on about rulers.
Well there is a big difference between that chunk of wood with
marks on it and a steel rule. A good steel rule will make the
differnce in how well your Starlet fits together. Here's a little
test for you to do ( I'd really take the time and try this it
will open your eyes). Go get your tape measure, a yard/meter
stick and a ruler
- and a pencil. Take a peice of paper and make a mark 6nches
or 15cm with each. along the edge. Measure from the same corner
- and try to get the mark exactly 6".Ignore the other
marks when you do this and just concentrate on the markings what
your measuring with. After you've made all theree marks look
at the edge. Is there just one single mark or three? If there's
more than one mark which one is right? Well the simple answer
is probably none of them but not to worry. What I would do is
first take that tape measure and put it away until you build
a house. I'd take the wood ruler and give it back to the kids.
If the steel rule is well marked then I'd use it. Tape measures
don't have any excuse to be used around an airplane structures.
Generally they are inaccurate for a couple of reasons one is
they are inexpensive and the accuracy they are capable of is
fine for a house. Even a steel tape will stretch just by being
pulled on and then there is tempurature effects. Unless your
building your work table keep these in the drawer. Wood rulers
can be affected by wear, poor markings and humidity and tempurature.
They are inexpensive
- and that does show up when you are tyring to be accurate.
Steel rules come in a couple of grades. One is construction grade
- and isn't marked in small increments. I've been using a steel
draftsmen rule. This is fairly accurate and well marked. This
is what I would reccomend you purchase. It really is the one
place where I'd spend the money and get the best you can find.
It more than pays for itself afterwards (don't let anyone borrow
it....). Steel is stable, isn't affected by tempuratures or humidity
so it doesn't change length. The markings are really an indication
of price, constructin grade will have thick easy to see markings
and these can be bigger than your measurement. It's hard to measure
to 1/64th of an inch when the mark is an 1/8th thick. So you
go out and buy a good steel rule but the measurements still don't
jive on the paper. There are a couple of things to do. One is
to purchase other rules from the same brand. For example the
steel ruler I have is made in 30cm and 1m lengths. I purchased
both and the markings when compared are exactly the same. I know
I can use either one and retain accuracy. Any measurements I
make are made with just those two rules. As long I continue to
use them or refer to them I know the parts are measured the same.
That really is the key thing to follow throughout your building.
Get a good rules and then use it from start to finish.
- SPIRIT AND BUBBLE LEVELS
- The two types of levels you will use are a buble level and
a spirit level. The bubble levels are the same ones you see used
in carpentry. I don't think there is a need to buy an expensive
one, the accuracy comes from the length not the material. The
spirit level is basically a tube filled with water. This gets
used to measure differences in height over long distances such
as wing tip to wing tip. These are easy to make from common materials.
Clear hose is all you need. You fill the hose with liquid and
compare
- levels. Some people put food coloring in the water to make
it easier to see, one french design suggests using red wine.
I wonder if red wine has a milspec ?
- PENCILS MARKERS
- There are several types of markers you want to have handy.
The type pf marker you use depends on the material you are marking.
For example a pencil is good for marking on wood parts but is
a no-no on aluminum. A felt pen will work on clean aluminum but
will not give sharp marks on wood. Pencils with soft and semi
hard leads, sharp of course. The cheap mechanical pencils work
well. Felt pens with fine tips for marking on metal. These are
called "sharpies". I've also used roller ball pens
on wood but I'm not sure they will last too long that way. You
really do want to watch what marker you use on what material
as it can cause problems down the road. For example a pencil
can make marks on aluminum but it also contaminates the surface
with graphite and can put a scratch line in the surface which
could lead to corrosion or a stress crack down the road. A felt
used on wood tends to bleed out and you get a fuzzy line not
the sharp one you need, it also acts as a stain and is hard to
hide. When your working on an airplane don't even think of using
a metal scribe, thats for making gutters and furnace duct's not
airplane parts. (scratchs can lead to stress risers and cracking)
- Clamps
- What else can be said about these other than you can never
have enough. That might sound like a bit of a joke but it's not.
If you see someone working on a project and the part seems to
consist of more clamps than wood, I'd ask if they had enough
clamps. I'll bet money the builder will say he could use a couple
more. If you know someone who hasn't read the part of this page
that warns about not loaning out tools, go to thier house and
borrow all thier clamps. There are a couple of different types
of clamps, each works slightly differently. The ones you will
work with might be C-Clamps, strap or ribbon clamps, pipe clamps,
spring clamps. I'm not going to go into how each works here,
you will find you will use them in more ways than the way they
work best.
- I think there are only a couple of things to watch when using
clamps, one is to have something to protect the part you are
working on from damage from the clamp itself. What can happen
is that you clamp a part and the metal part of the clamps will
dig into
- the wood or aluminum. The way to avoid this is to put a peice
of scrap inbetween the clamp and the part being clamped. This
way the scrap takes all the abuse and your part comes out without
a mark. The other thign to watch for is not to overclamp a joint.
Some older glues needed to have lots of pressure to get a proper
glue joint, newer ones such as epoxy just need to have the parts
more or less in the same location for a good joint. If you clamp
too tight you can squeeze the glue out and get a dry joint. Other
options if you havn't been able to borrow enough clamps are fairly
simple. You can use nails, screws, or homemade clamps made of
string and a stick.
- If its the right kind of joint even those weights from your
unused dumbells will work. Remember the whole idea of clamps
is simply to keep the parts being glued close enough untill the
glue dries. After that the glue does all the work.
- Utility Knifes
- You will use a couple of these for cutting and trimming.
The extending razor knife is cheap and you can replace the blades
with a new one. These are the knives that the blades slide out
and you can break off the dull end to get a new sharp blade.
The handles are plastic and have a lock to stop the blade from
moving. You might want to get a couple of these in different
sizes. The small ones won't give a straight line as easily on
large parts, the blade flex's a bit more and the handle doesn't
give you enough of a grip. These knives work very well if you
use them as they are intended to.
- They are meant to be drawn or pulled at an angle with light
to moderate pressue. The blades in these knives are flexible
so if you put too much pressure they flex and your cut can go
off the mark. Because they have score marks on the side of the
blade to help snap off the dull bits, pushing too hard can also
result in the blade snapping off.
- Disposable Brushes
- There are two types of disposable brushes, one is the foam
brush and the other is a bristal brush. The foam brush works
well and holds a lot of material. They will work for finish work
as well as general use. A lot of people who finish furniture
use these to brush on finish's as they don't leave brush marks.
The downside to these brushes are that the foam will crumble
after after a few uses, and you need to make sure that you check
that the foam is compatable with any solvents you use. The other
type of dispoasable brush is a bristal type. The bristal's look
like straw and the handle is plain wood. These brushes are good
for fiberglass work, they tend to shed the bristals so I wouldn't
use then on any finish work.
- Misc Containers for parts, solvents, glues
- These can be anything from old paint buckets to plastic or
metal containers. For example I use an old coffee tin full
of solvent to clean brushes. It's a handy size for painting as
its easily moved and handled as you crawl around the airplane.
Old margerine containers with lids are great for sorting out
nuts and bolts and other bits.
- Unwaxed paper cups or plastic cups
- If you are using epoxy glue you want to mix it in unwaxed
cup. Generally you won't be mixing more than an ounce at a time
so a cup size or smaller is plenty. The reason you want unwaxed
cups or plastic is that the wax can be scraped off the side of
the cup when mixing and get into the epoxy. Ths can cotaminate
the bond or make it fail. Parting compounds used in composites
are generally a form of wax.
- Stir sticks or tounge depressor
- These are cheap and clean. I use them to mix up the epoxy
and then apply it to the joints. You can find these at any hardware
or crafts store.
- Sandpaper
- There are several types and grades of sandpaper, aluminum
oxide paper, garnette oxide paper,silicon oxide wet and dry and
emery cloth. The biggest difference between these types is how
the grit is formed and attached and the backing media.
- The paper backed types are for dry use only, if you get these
wet the abrasive materil will slide right off the paper. These
are fine for sanding wood metal or plastic prior to finish coats.
Don't buy the cheapest paper you can get as these will tend to
leave grit on what you are sanding. There are foam sanding blocks
and steel wools you can use as well. The foam blocks cost more
than paper but work quite well. Steel wool acts like very fine
sandpaper.
- VICE
- This is one object that you will use a lot. You can work
without one but it comes in handy. There are a whole array of
different styles and sizes. A good vice will set you back at
least $50 at a store (can you say garage sale boys and girls?
I knew that you could) You will want a vice that has at least
a 4inch/100mm opening. After you have a big enough vice the most
important thing is that its securly attached to something.
- The whole idea of a vice is to hold something in place while
you work on things, theres no sense having one when its attached
to a table that moves around when you work.
- DISPOSABLE LATEX GLOVES
- These are the surgical gloves you see every where. They are
cheap and available in various sizes. I purchased 100 large pairs
for $10 from the local plastics supply store. I've seen them
in a few colours so if your into fashion staements in the shop
(I don't think there is any difference in material or intended
use btw) you can get white, blue or green.
- COTTON GLOVES
- A lot of people develop allergies to epoxies from contact,
and some develop allergies to the latex gloves they wore to protect
them from the epoxy. My solution is to get a pair of thin cotton
gloves and wear these, then put the latex gloves over those.
I found this had a few additional benefits such as I used fewer
latex gloves and I could work longer. My hands didn't sweat so
my comfort level was up and I could wear them longer. Instead
of using up two or three pairs of latex gloves I could keep one
pair on for the entire job. Before that I would glue up a few
parts and then shuck the gloves off as fast as I could because
they were so uncomfortable. Needless to say more than a few pairs
got wasted this way.
