Gathering stuff for the first panels and other materials while waiting for the shop. I rescued a couple of seized 1/2 hp pumps from the dumpster. These were completely trashed with some kind of vapor that caused extensive rusting of the cast pump stators. The innards were really full of gritty rust, cementing the vanes in the rotor. In each case a pretty beefy 1/2 hp direct drive engine would not turn them!!! For my use I guess these will do, even if not perfect, as I don't need a micron level vacuum. I think the plan would be to debulk with a shopvac and turn these beauties loose on the infusion and bagging.
