RE: [bolger] Re: Questions on Foam
Lincoln,
I used R-guard for the Pointy Skiff flotation. Don't know about its
resistance to fuel and the effect epoxy has on it but I plan to find out
soon. I'll let everyone know. I cut mine with my trusty sabre saw followed
by clean up with my trusty shop vac. No fumes, fires, hot wires, etc.

Aircraft Spruce and Specialty used to have a cheap kit for a hot wire
cutter that works fine. Maybe they still carry it. I'm sure you can
surf and find them.
If you want to play now, get a 12V battery, a charger or maybe another
battery, some .020" steel wire (maybe stranded steel fishing stuff,
tho music wire works ok). Make a bow about 3 or 4 feet long to hold
the wire in tension (10 or 20 lbs????), plus wrap some wire in a
spiral around something like a brick that won't burn or conduct.
connect the two voltage sources in series and to one end of the bow.
Connect a wire from the other end of the voltage source to one end of
the spiral. Clip a wire from the spiral to the opposite end of the
bow. Adjust position of clip on spiral to adjust current. Should
slowly and easily cut through styrofoam if current is right. DON'T cut
urethane as apparently it kicks off really nasty fumes. You will want
some ventilation anyway. Be careful that you don't have anything
tremendously flammable about, particularly if you mess up momentarily
and the wire gets red hot. This is an easy, non-critical process. Just
make sure you have some extra wire as you may break some. Don't use
copper wire. Proper size guitar string will work if you're really in a
hurry. Works on expanded bead foam just as well as styrofoam.

My experience with this foam is based on model a/c and homebuilt a/c but
this is what I think. ( free advice is worth what you pay for it!)
1. It ought to be just fine for floatation.
2. gasoline will melt it as soon as it touches it.
3. It is very easy to make a hot wire cutter, and it is the easiest and
neatest way
to cut it. If you search under hot wire foam cutting you should find
plenty of
info on how to. If you need further info, I can tell you how to make a
simple
one.
4. I think that the best adhesive is epoxy. It will not harm it, and it
will keep
gasoline from harming it. Do not use polyester resin, it will eat it
up.
5. Epoxy.

Soon the decision on foam buoyancy for the Diablo has to be made.
Locally I can get the white styrofoam called "R-Guard" in two inch
thick sheets. A few questions, does anyone know;
1. Is this stuff OK?
2. Is it fuel resistant?
3. How do you cut it? I seem to recall any saw produces tons of small
particles that fly around and stick everywhere. Someone told me craft
people use a "Hotwire" cutter, anyone know what and where about that?
4. Is there a perfered glue to hold the pieces together to make a
block ? I was told epoxy disolves it.
5. Is there a coating, -paint,varnish, something else?- that will
give it a little protection?
Boatshop shutdown until Saturday am, but still building in my head.
Thanks for any and all thoughts,
Rick
