Of course, I don't rebuild spindles so take this with a grain of salt, but in my view, it seems the two most important things that must be on the money, would be the type/amount of grease in the bearings, and the perfect amount of bearing preload. I think the rest of it would be standard disassembly, cleaning, cleaning, cleaning, and inspection. I believe Fadal documents their recommended preload procedures if I remember correctly.

The video of Global Spindle Reman made me cringe several times.

I always wondered how they remanned spindles. Now I know that I would never want a Renan built by them. Jeeslus that video had tons of cringe in it for high dollar spindles. If I had time and needed an new spindle I’d probably try to do it myself.
