John,
Have you considered getting an “adjustable”
epoxy pump? That’s what I got for the Jeffco epoxy I use on my Lancair
project. I do a calibration check every so often, just to make sure its still set
properly.

Gentlemen; Thanks for the input on the
epoxy. Yesterday I may have ended up with too much hardener. The
leftover material in the cup didn't do anything either. If there is only
a + or - 5 % window for the hardener, as Joe stated, it is really hard to mix
small amounts to this standard. Today I mixed another small batch very
carefully and it turned out okay. I guess another question would be, does
this material ever get hard or does it just stay in the leathery state as Joe
stated. I have covered the wood wings of the Wittman Tailwind with the
West System and those pumps are real handy for the West Ratio. JohnD
