As the Enco 1024 is an import it is almost certain that you have
module [metric] gears and not P.D. [inch] gears.

See Law's book on gear cutting for indepth discussion of P.D. v
module. see http://www.powells.com/biblio/66-0852429118-1

I have this book and find it to be a valuable reference in
addition to telling you how to cut both involute and cycloid
gearing. Powell's is good to deal with.

I'm trying to replace some crashed spur gears in the QC box on an Enco
1024. Enco is no help. I downloaded a Martin Gear Catalog and am
trying to figure out what to order.

I'm measuring a Pitch Diameter = .773
How do I determine what the pressure angle is?

The valley between each tooth is radiused. Martin calls that a
Shaper-cut profile. Is that significant?

The guy a Purvis Bearing talked like this is rocket science.
Is there a better way to do this?
