I'm very envious. Working turbos _with_ matching controllers are almost impossible to come by.
Dozens of them were auctioned earlier this year after the bankruptcy of Mapper.
But I had no idea what to do with them so passed on them. Dont even know how to do metal disposition etc.
Is that something you can do at home ? Dont you need a cleanroom? What will you do with it?
However I bought a Edwards XDS35i industrial vacuum pump that already had 26000 hrs on it (found out later after pickup) still would go just over $900. New thry are in the $20k i believe. A simple gasket replacement set will set me back $700 so I hope it will last me a few years. It works but also had no caps on the input output.
I have to find some matching hose and adapters and a decent prefilter is necessary i believe. The thing can only go from room pressure to 10mbar five times an hour but can run all day long at 10 mbar , weird devices
I want to use that one for a diy p&p machine and vacuum table for my cnc mill, I know way overkill but fun.
