Help!!! Mallory Zb distributor housing weld repair

[Bored&Stroked]

The other thing the lathe gives you is the ability to put a dial-indicator and check to see if the end bushing bore is in alignment with the housing OD.

In almost all cases (even with proper setup) welding distorts/moves things. You may need to over-bore the end bushing in the housing and make a new custom bushing to ensure the bushings are running true to the same center axis.
