Re: [RCSE] Mold Help?

[Larry Taylor]

Here is a trick that I learned from a world champ.  you take a long stick (8 
to 18 inches) and get some items that weigh the same ( Dimes, 
Quarter,Dollars coins)  Take 10 coins and put it in a little plastic cup. 
The cup has to be suspended by a wire loop going around and bent up to the 
long stick where you drill a hole and the hole thing pivots in..  The other 
end you do the same thing with a cup to hold the epoxy in.  . With nothing 
in the cups it should balance. If not make it balance exactly in the middle 
of the stick.  Now take the 10 coins put them on one side and put as much 
epoxy as you need in the other side and than find the balance point of the 
coins and epoxy. Add the 11th coin and pore in the catalyst in the Epoxy you 
will now have your 10 to 1 ratio. This is the same with 5 to 1 mix with 5 
coins. This is fast and accurate. I had forgot how to do this my self till I 
was shown. I use to put one washer on a balance beam and dump washer on the 
other side till it balanced and I would have 100  with out counting and it 
works!!  I counted it once just to make sure for myself

Hi All,
I know this is off topic but I need help with a mixture ratio for ACP's
tooling resin and thought someone here might know.  My digital scale
died and I can't find one locally.  The mixture ratio on the can is 10:1
by weight but no mention of mixing by volume.  Anyone else use their
tooling resin and have any idea what the mix by volume would be?
Snowing like crazy here and I'd like to lay up a mold while the weather
is bad.
Happy flying,
Jim
