Ran into an interesting issue with the lathe today, I can only get the power feed to feed in the reverse direction. The half nut appears to be engaging, but doesn't want to feed forward towards the chuck. It will feed all day in reverse, so not sure how to troubleshoot.

Any suggestions?

Yes I have suggestions: Is the leadscrew only turning in one direction or does it reverse properly? If it is not reversing then you must have a problem with the tumbler reverse gears.
If it is reversing, then there must be a problem with the half-nut assembly under the apron- worn or broken half-nuts or carrier

Whatever broke the half-nut lever (in your first posting) couldn't have been good for the mechanism behind it- the problem is likely there

The leadscrew is turning both directions, so the problem is in the apron...may end up pulling the apron again to inspect the half nut.
