Hi!
Im looking for additional info about Dave Cowden's high speed spindle.
I was reading about this design here:

Some more additional questions for Dave:
- How many pcbs are you making with it? So how durable is it?
- The cpu cooling fan can support this (high) speed? (50-90k) How the skate bearings are wearing out?
- Can you post some additional photo (from inside) or design drawings (or technical schematics) of the spindle?
- I dont really understand the tool holder, how are you changing the milling bit?
- How robust are the pvc tube? It does not affect the overall robustness or durability?
- Please post some photo/video of the overall machine when milling
Any more info is really appreciated!
