Thanks for all the help!
Here's one (actually two) more questions: SDP/SI has 32DP 20° 24t pinion wire available in either brass or carbon steel. Which material would be preferable for a pinion? If carbon steel is preferable, would we be able to case harden it with either heat+
surface-hardening compound or oxyacetylene flame hardening? Is this needed? (I tried looking up the material properties, but "carbon steel" is pretty generic...) Searching revealed two
good posts from Dave on these heat-treating processes.
While machining press-fit pinions may be new for us this year, I'm sure we can have fully functional gearboxes sooner than the 5-10 business day delay -plus shipping- currently plaguing the P60 gearboxes.
