Hello from BC.
I'm repairing a Kearns model S borer. The tower shaft worm wheel is wallered out. Cranky thing suits a 4 start worm pinion.
3" od X 0.755" wide, 22 tooth, tooth depth 0.255", helix angle 13 deg.
The steel pinion is 2.427" dia, length 1.545", 4 start, 1 turn in length, tooth depth 0.241, included angle 40 deg.
I need the worm wheel in phospher bronze.
The pinion is on the tower shaft and the worm wheel is on the counter shaft.
Any takers.
Regards
BC
