I have excellent results machining the laygears using a diamond bit at high
speeds on the lathe. I can also bore out destroyed laygears and press in a
sleeve which I then machine to accept a pair of the caged roller bearings
B-1314. I have many of these modified laygears running for a number of
years.
Machinists a like doctors... there are always many opinions.
