Hello from the old goat.
My Kearns borer is dead and I need a worm wheel made.
3.09" dia X 0.755 wide, 22 tooth, tooth depth 0.255"
To suit a 4 start worm of 2.427" dia, length 1.545" long, 1 turn in length, tooth depth 0.241" 20 deg PA.
Wheel to be of phospher bronze.
I can do the bore and keyway.
No Rush.
