Review on Boston Gear GA45 Change Pressure by Darion Wooten

Revainrating 5 out of 5

Suitable for Hardinge lathes!

These replacement gears mount directly onto the transmission shafts on your Hardinge lathe. However, note that they will NOT mate with standard Hardinge gears! Hardinge gears are 22/29 short teeth with a 20 degree pressure angle. Boston gears have a pitch of 20 and a pressure angle of 14.5 degrees.

Pros
  • Power Transmission Products
Cons
  • No Instructions
