Could you determine and post specification data for the Gear-to-square bar(shaft) torque capacity, and gear tooth load limit as well?
**Based on our experiments, the gear teeth will fail under the following shaft load torques.
12-tooth, 40 inlbs
36-tooth, 120 inlbs
60-tooth, 200 in*lbs
The Square Broach will fail under a load of approximately 33 in*lbs of load torque.**
