I have a Delta-Rockwell 11" (#25-100) lathe and I'm looking for a

as a spindle nose protector. Anybody have any experience/advice
regrinding a #5MT to #4-1/2?

Yes, don't. According to Royal, the taper is actually a short 5MT.
Put prussian blue on your 5MT and check. I got a 5C adapter from
Royal that works well for mine (same model). The part number is
R184024. I made my own spindle nose protector and drawbar. See
http://www.metalworking.com/DropBox/...oj-5CParts.JPG

and others in that series. My homemade adapter sleeve sucked, and was
replaced by the Royal unit. The rest is in service.
