In Response To: Epoxy: Beginner question- epoxy pumps (aikijay)

I use pumps. West says that when (they say if, but if you keep your pumps a long time it will be "when") they clog, heat them with warm water and the goop will liquefy and you can get rid of it. Kind of like adding warm saline to a crusty nose, and close to the same color, too... shove some chenille pipe cleaners up there. I do that a couple of times, then I just get new pumps.

As for pumping the right amount- follow the instructions. They will tell you how many times to pump (usually one pump for resin, one for hardener to get the right amount. West uses different size caps on the products so you can't mix them up), and they will all tell you pump resin, then hardener, resin, then hardener, for however many pumps you need. You will never "forget" how many of anything you need. If you're standing in front of your resin you need hardener. If you're standing in front of your hardener, you're good.

I use pumps for metering small amounts as well, but I use them to pump epoxy into cups and do the measuring with a scale. For really tiny amounts of epoxy like I frequently use (epoxy is expensive and not that environmentally friendly, so I don't waste it if I can help it) I got a scale that measures in tenths of a gram/oz. I got it from Harbor Freight, under $10, and to test it I measured the same object 10 times and got the same weight each time, and that's all the accuracy I need. when it gets gooped up, I'll just buy another one. My first scale was fancier, but it didn't measure in tenths, and was a lot more expensive.
