I made this set-up yesterday morning. The shop is intended to keep it at a moderate and uniform temperature before mixing. The pumps seemed neat but the hardener is too viscous to pump and the resin is pretty slow. $6 wasted. I pour from each bottle into a paper cup set on the balance. I hung a washer on the beam to balance the weight of the cup, or tare. I write down the weights and batch number. Works great.
This morning the epoxy is all pretty much set up. I put a few hundred watts of electric heat during the night and that may have been good for a few degrees above the 35 deg minimum atmospheric temp. I suspect it would have done pretty good without the heat but I need anything to speed up this process.
The cups were the recipients of yesterdays mixes arranged sequentially. Should a mix be bad, I could trace it to my record of weights to figure out how I goofed.
I have epoxied another panel this morning and only one more to go! Then several days of grinding, filling, and laying glass cloth, that I do not have yet.
