Othmro Handwheel

If you have a Sieg SC4 these (M8 threads w/10mm bore) handwheels replace the factory knuckle breaker chrome handwheels perfectly. These are for the cross feed and compound dial handwheels. You remove the factory nut, chrome handwheel AND the thick spacer washer . Replace with this handwheel and the factory nut. Besure to line up the key-way on the shaft to the handwheel.I have 2 Little Machine Shop 8.5 x 20 , LMS 3540 or 7500.Also, the pics i posted makes it look like this handwheel is the same size as the carriage wheel...its not, these are smaller.

Used this for my home made bow press. It works perfectly. The only thing I latter considered , was a larger circumphrence would make it easier to turn under a load.
