Gentlemen:
I have been watching the exchange regarding this question and I agree with
Chuck about re-wetting the cups. In general, the densities of the catalyst
and hardeners are close enough to consider them equal for the weighing
measurements. If you weigh the parts in separate cups before
Cole-Palmer Instrument Company sells many types of scales. I prefer the
mechanical Ohaus for its dependability and weight range.

West epoxy is good stuff, but highly overated in my opinion and
the mixing ratio is a pain.
My favorite is System Three, it has a 2 parts resin to 1 part hardener
ratio and 3 different hardeners.
I have also been using epoxy from CMI (1-800-522-2599)
I use the slow B-27 resin with A-40 hardener.

Came across Varathane (I think) water-soluble varnish in a spray can (both semi-gloss

of wiping/brushing on the traditional liquid version? Seems like it would be possible
to get a lighter coat; or am I
One of the problems of digital (electronic) gram scales is that they are
prone to interference. On mine, if I use a cordless phone near it, it
whigs out.

David you make a good point... perhaps you could check my math. West System
pumps are available in sets only, as I understand, one for resin and one for
hardener @ $8.30. Since I use two hardeners and one pump failed in the
middle of a lay-up... I used four sets for a total of $33.20. We
Hi Gang,
I am looking to buy a foamie warbird for the upcoming festivities at the MWSC
at Lake Wilson Kansas. My question is as follows, if you could only have one
warbird for both combat and foamie warbird racing which one would it be?
Also, if anyone has a foamie they are looking to sell
Eric,
The EH airfoils do well on deltas if you use a small amount of up
trim to make the pitching moment slightly more positive. The up trim
will be negligible when flying at high speed, but more substantial at
slower speeds. Inverted flight will not be a problem with an EH
section.

You guys must be some ham fisted bruts. Slow and easy on the pumps. Just
like a good woman. Everything will go smooth...
I haven't mentioned the
measured inaccuracies of the pumps
I haven't mentioned the

No, but please do! This type of pump has been around for decades and seems
to be adequate for chemists/biochemists and other applications requiring
better than the +/-10% of some resin systems, so it would be interesting to
