High Vacuum Chamber for THIN FILM DEPOSITION Build

I built a physical deposition chamber, for now it's just evaporative deposition but I plan on adding a few other variants. The thin films created can be used in many ways. The chamber still has a ton of space leftover and I have some more equipment coming so hopefully I can do more interesting things. Sorry there's no footage of lathing the feedthroughs, they worked nice with a cut o-ring and some heat shrink. Make sure you cut a slot down the holding screw threads to vent behind em. The 2 copper feedthroughs allow (with a center tap) 2 tungsten boats with different metals so I can avoid opening the chamber in a multi layer coating. The pump down takes about 45 min. to get to 10e-5. I can use a small steel hemisphere with a kf40 hose on the top for use with a secondary high vacuum chamber. The shutter was aluminum flashing with some steel stuck on one side so a neodymium magnet on the outside of the bell jar could move it around without a feedthrough. This build was really fun I got everything from mcmaster, K.j lesker, ebay and what I already had This did cost a bit to make: diffusion pump- $160 mechanical pump-$140 plate- $270 (ouch!) valves- $90 gauges- $200 misc vacuum stuff -$120 bell jar - $140 (stupid) other stuff - maybe $100?
