Possible steps for temporary amateur Rube Goldberg repair:
1. Insert short pieces of rod (or something like finish nails) through the "oval" parallel to but on the outside of the bushing to restore the bushing to its proper shape and location.
2. Reinstall auger, and secure the filler pieces with furnace cement.
3. Say a lot of prayers to Saint Frederick of Altensteig (the patron saint of old EFM stokers).
4. Start plans for replacing the pot.
As always, should you or anybody else reading this actually follow such a plan, the secretary will deny any knowledge of your actions, the existence of this post, and even the existence of this forum. Unless it works.
