In Response To: Epoxy: getting good mixes *PIC* (Paul G. Jacobson)

: Pumps are great for dispensing, but I don't trust their accuracy
: for measuring. Pump your materials into measuring cups. I use
: inexpensive disposable 7 ounce to 9 ounce, translucent (not the
: clear styrene) cups, and mark them for how much I need. To keep
: the marks consistent from batch to batch I made a jig from
: another cup. Stack a fresh cup in the jig, mark a line on it,
: and pour or pump the resin or hardener into the cup up to the
: line. Go no more than halfway in any cup and you can dump the
: contents of one cup into the other, stir to mix, and away you
: go. Dump it after use. Cups at any grocery store for about three
: cents apiece.

: Here is a picture of how I make the jig.

: If you want to check your pumps, use them and put 2 or three pumps
: into a cup, mark the height of the liquid, and transfer that
: line to a master, or jig. Do the same for the hardener. Mix and
: use whatever you pumped out. Later, you can mark up fresh mixing
: cups and pump into them. If you get any air bubbles, or short
: strokes, the amount you pump will not come up to the line, and
: you'll know something is off before you mix. It is a good way to
: doublecheck your mixes and maintain consistency.

: Hope this helps.

Ive used those pumps for many many years and the only failure we've had even with the classes was from way below normal temperatues, thanks to the person who owned the shop we were using. I've yet to see a problem using these pumps, been at this for something like 25 years btw.
