Homemade Vacuum Pump

[Toolmaker51]

"...vacuum between galaxies..." lol, pretty severe description of nonexistent atmosphere. The jar is still boxed, unused, from a distinguished federal manufacturing plant. No other bidders. The carpet remnant is a better solution than race blanket, especially with a layer of wire mesh.
The mention of Veeco brought back memories building HFET's literally by the score, from wirebonding, belt soldering the lids, vacuum leak and PIND tests.
Us toolmakers get around, but no Beach Boy's song about it
