I am attempting to cut a keyway in a drive wheel I am building for a belt sander, the keyway is 3/16" a couple inches long, the shaft is 5/8 "
I bought a 1/2" boring bar. it has a 45deg and 90 deg square 3/16 holes
I have tried both without much success, either the bar flexes or not much happens? I am using a 13x40 Lathe, the wheel is Aluminum so obviously my tool is not sharpened correctly I have tried several grinds, there again with not much sucess.
What angle should I be shooting for in either the 90 or 45 holes? I am only trying to take at the most a 0.02 cut? Using the carriage, I did shorten up the bar so that just enough is sticking out of the holder to make it through the pulley.
Any insight at all to this would be appreciated.
Obviously I am a newby.
Thanks in advance
