Taking this route for spindle

[Ross77]

First off,Ross...have you tried drawing with a mouse? :lol:

Yeah every day, the trick is to wrap its tail around you thumb then he cant get away

Anyway back to the spindle. Ok so a bit more info, but still need to know speeds and shaft diameters really.

Even with the 20mm plate you are never going to get both bearings concentric (let alone be able to preload them) unless they are machined in the same operation from one piece of metal, Fact. also how are you going to keep dirt out? 4 friction seals will just generate more heat and problems.......anyway with out knowing the speeds, bearing types and usage its all speculation

I'm not professing to be a spindle expert its just I have spent the last 2-3 weeks looking at every design conceivable and its usually the tried and test ones that work:whistling:
