Epoxolite
Ed Smega
epoxy based filler that I really liked. I don't usually use fillers but
this stuff made great wing fillets and I am about to start a project where I
may want to make wing fillets. I haven't seen epoxolite in many years, has
it disappeared entirely or have I just not looked in the right places?

SIG. Ain't he that child molester guy?

It was SIG. I think it was largely regular epoxy with lots and lots of
microballoons, although there may have been other fillers in there to
make it more thixotropic.
You can get microballoons, that may get you close enough.
If you don't mind the smell I once saw a version of Bondo that used
microballoons instead of talc as a filler.

have used it for fillets and all I had to do was wet my finger and
smooth it out..only took a bit of sanding when it set up.
Why not give Sig a call and see if they still sell it.
Sig doesn't have an up to date catalog..but their 2001 shows it as
available in 5 oz 8.75 oz and 2 quart (!!!) sizes at 9.95, 15.95 and
(get this..) 125.00.
Stock numbers:
SIGEP001, SIGEP002 and SIGEP003 respectively...
Good luck..

there's no way to sand it to shape afterwards. It's like concrete, only much
harder.

There is an aviation product made by Poly Fiber called "SuperFil". It's
mixed 2:1 and is very light -- specs say a full gallon would only weigh
3.68#, thought you buy it in smaller amounts!
Pot life is one hour; cures in 8 hours; cure to sand 12 hours.
It adheres to most anything, sands far easier than Sig, let alone
Micro-Balloons and Epoxy, and feathers wonderfully. I've used it for all the
filling necessary on my Bonanza as well as a FW-190, which has huge fillets.
Both had canopies/cabins that had to be faired into balsa. The Bonanza is
now 4 years old with no cracks showing.

I haven't seen that or Celastic in years. Probably victims of the EPA.

Ed, I have three sheets of Celastic in heavy and less-so.
I have to admit that I was an unimaginative modeler. I messed
with the chemicals since the fifth grade and I never knew a fellow
could get high on them...by accident..until about 1975 (I was only 41
then) and a fellow and I were building three Thornburg Top Cats in an
assembly line in my 12' x 24'.
The next task in the process fell to me and was to slather the
two pieces of 6" x 10" Celastic on the top and bottom of the wing
joint of each wing. I figured the fastest way to do this would be to
get a dining plate, fill it with thinner, and sop the stuff through
that.
This necessitated waving a saturated piece in the air in front
of my face, flopping it down on the wing joint (on the bench under my
nose) and mashing the goo into the wood with my fingers. I would have
to keep dipping my fingers in the thinner to keep them from sticking.
I had done this many times before...quickly on one wing, but
not three wings.
I was getting a little light-headed and sillier than normal
and when I started giggling, my friend said something about the fumes
getting strong and he looked at me, ran to the door, threw it open,
opened the windows and told me that I was white all around the mouth.
This, I must have thought hilarious, because I burst in to
near-hysterical laughter. He led me to the porch and sat me down on
the steps. This seemed childish to be led outside and made to sit on
the porch ("and don't go play in the street, young man!") and this
made me laugh all the harder.
Then I noticed that each hair on my arm had a little diamond
at the bottom of it...no...wait...it wasn't a diamond...it was a
droplet (a real neat one!) of sweat.
This, too, seemed funny. I had never seen sweat that
precisely placed before -- or since, I might add.
I remember leaning back on the porch real mellow like and
looking up at the birds in the trees -- the birds were unusually
colorful and their songs were near angelic.
Unfortunately, this wore off after awhile, I was aggravated
again that I let a guy talk me into building a model for him and I
knew he would just crash it...and the real world came back.
I learned then there were was much that could be said positive
about the stuff we toyed with. But I am glad I never discovered this
when young and a little more stupid.
I remember it took three days for the taste of plasticizer to
wear off.
I would like to see someone have that much fun with an ARF!

and the thing I particularly like about it is that nitrate dope gets a
strong bond to it, and the silk covering I use on sheeted fuselages will
not lift to shorten chord across the inside curve of the fillet. I
can't say that for epoxy and microballoons.
I never had any great trouble sanding it, except that it gums up the
paper a little; but then again, we're making airplanes here, not trying
to save sandpaper...
I'll have to check out superfil next time I get over to A/C Spruce,
although my Bonanza is aluminum, and don't need too much filling.

Yes, it is- a 1955 F35 bonanza, currently with a few radio
problems. After routinely replacing the battery every two years or
so for the last 16 years, I hooked it up backwards this time. It's easy
to do since the cables are long, unmarked, and the battery is not well
labeled either.
It started, and only after the smell of frying electronics filled the
air, and the failure of the radios to turn on, did I realize my error...
I fixed one of them, and fuses protected a couple more, but I gotta fix
or replace a couple still.
Talk about your bonehead maneuvers... -Paul

And are the cables _still_ unmarked, or do they now have callouts for
the unwary?

You sound as bad as me when I was in high school.
I used to assemble my control line models in my upstairs bedroom. The only
money that I had to work with was my school lunch money and whatever else I
could scrounge up by doing odd jobs, etc.
One Winter evening I had finally accumulated all of the parts needed to
assemble a Scientific Stunt Master kit. I had the kit, a brand new Fox .15X,
one 4 oz. bottle of black butyrate dope (Testor's), a single solitary paint
brush, some brass screws for mounting the engine and a couple of old razor
blades. No, not single edged razor blades, that would have been too easy.
I began work after I finished doing the dinner dishes (one of my family
chores) and worked and worked and worked. The paint and glue fumes (Ambroid)
made me lose track of the time. I had assembled the kit and just finished
painting when I glanced toward the window. One of the neighbors was leaving
for day shift at "The Plant". It was morning and I had school that day.
Where did the time go? Later that year, I flew the dickens out of that
model. It was the first model that I intentionally flew inverted.
Looking back on it, how did the Ambroid dry quickly enough to do all of that
work in one night? Not likely, is it? But that's how I remember it.

Celastic was dry strips of cloth that had been soaked in a kind of thick
binder, kind of like those old muffler bandages that you could buy to repair
car mufflers.
Instead of soaking it in water, as you did the muffler bandages, you soaked
this in dope thinner. Apply it to the surface that you wanted to join and
then let it dry. The stuff was kind of an early attempt at fiberglassing, I
suppose. It did have its uses.

vinyl adhesive base and sands well. Need to avoid high pressure on the
sanded surface to minimize heat build up so that you don't tear the surface
and get little gummy wads of stuff.

Paul,
Sorry you got bit by the reversed battery thing, that sort of thing has
always worried me. FYI, if you look at the connectors, the post size is
different for each pole, sort of a poor mans guide to systems not well
marked. I know it is closing the barn door after the horse is out, but
there you are.
I found out how and were to get a Celastic replacement...
Speak to your professional air conditioner folks, it is used to build and
repair air duct and air boxes around air handlers. Guess how *I* found out.
Cheap scum who built this place put the expensive systems in where we could
see them. The out of sight air handelers were the cheap garbage that
naturally failed in dramatically less than 10 years, as did the water
heaters, and several plumbing connections. Never do business with a man who
does not manage his own projects...
