I was shooting for a slip fit, but my measurements weren’t as accurate as they probably should have been on the sleeve.
I still find it hard to believe that leaving a full 2.5mm gap all around the new 90mm spindle would have been adequate.
I can’t imagine that the face of the spindle casing would be as good at supporting work load at the end of a bit, as having the full spindle body supported in a sleeve.
Thanks for the input, I don’t think I’ll press it out and redo it at this point, if I start having trouble with the bit being angled or bearing life appears to be effected, I’ll look at making another sleeve with more focus on the slip fit.
This is for my home shop, so I doubt either of those will be effected enough for me to spend the effort.
Thanks
