I have to make a taper pin reamer for my Induma Power Feed Project. I looked at buying them but $60 for a tool I'll use twice is a little excessive. The pins are metric 5mm taper pins (got them from mcmaster-carr) I purchased some 1/4" A-2 Drill rod to make it from. I planned on turning a matching taper on the rod but make it extra long (so I can use it for more than 1 size). Then I plan on using my smallest carbide end mill to cut a flute (maybe 2) in the taper. Then I'm going to red-neck harden it and draw it back with a map gas torch. Hopefully I can ream out 2 holes to take the taper pins!
Any thoughts or pointers?
