[PSUBS-MAILIST] Press Fit

[Jon Wallace via Personal_Submersibles]

Alan,
Search the internet for press fit, bore, shaft...something like that...I found a tooling handbook that had a chart describing how large a bore to produce different levels of "press fit", from kinda-loose to needing a hydraulic press for insertion.  Wish I had book marked that web page now.

Hi, 
I'm wanting to press fit a bearing in to my aluminium thruster housing
& wondering if I could make a tool slightly less in diameter than my bearing,
fit it in the lathes tail stock, & wind it in to force the bearing in to the press fit.
  I have heard figures like 500lb force being used for press fitting, which I
won't get winding the tail stock, & probably don't require as there is not a 
lot of dynamic force on the bearing. 
  I imagine there will be a lot of trial & error involved getting the bore to
the right diameter, & this method will allow me to keep the work in the chuck
& keep doing fine passes until I get it to the right diameter.
Any thoughts or experience with this thanks.
Alan
