I have a old UNION TOOL&CUTTER GRINDER and want to make a extended wheel adapter
for it .
The shaft on the motor is .500" 1/2" , The threads on it measure .497 so i am
taking it as 1/2" with a little wear on the thread points.
When i match up with a thread guage ,it says on the guage 1/2"- 9/16 Whit. .
This confuses me as don't know what tap to use for the internal thread on the
any advise would be helpful [IMG]
