Re: When a motor does overheat

Put a straight edge on the block and head individually going from opposite corners, try and pass feeler gauges underneath the straight edge.
You would have to check the book for what an acceptable measurement is, but if you can see light it is not a good thing.

As for what straight edge, I don’t think a framer’s square is quite true enough.

If it is off a little bit you can try lapping compound on a flat surface, try your local glass shop, they might be able to give you a drop for cheap. Try for 1/4" or thicker. Also talk to granite counter installers, they usually have to cut out a chunk for the sink
