Every fusor and fusion system seems to need a vacuum. This area is for detailed discussion of vacuum systems, materials, gauging, etc. related to fusor or fusion research.

$200 for the correct set of pre greased bearings sounds very reasonable. A pair of the inexpensive bearings and 20ml of Kluber asonic ghy72 will run about $50. A chance at saving $150 is probably not worth your worry.
Many good tips are in the high-speed spindle bearing rebuild video. Clean is extremely important but honestly it is not all that difficult if you have good mechanical skills.

The TURBOTRONIK NT10 I have does not check very much. As I recall just the spin up time must be under 2minutes?? I think Jerry Biehler posted a schematic awhile back. Have fun.

Hello Hans,

Yes i was succesful, but i made a terrible work 😅 so i would not be showing such horrific things here.
The pump works great though, i just finished the dirver, im still programming it.
I opened another thread for that too.
