on 02024-09-02#Advanced-Tinkering #video about a homemade magnetron. Explains #vacuum considerations like vent holes for screw threads to prevent virtual leaks and face seals rather than radial seals (due to, he says, his inexperience). He used #3D-printing to make drill guides to transfer the precision of his 3-D printer to his drill and thence into stainless. He’s doing water cooling inside a copper plate in hard vacuum! But his water-cooling hoses aren’t exposed to vacuum. He’s powering it with the guts of a microwave and a half (one MOT and two oil caps) plugged into a variac. He got his metal parts machined by his video’s sponsor PCBWay. One of them cost him US$227, US$1170 for the entire magnetron assembly.
