Well, after fighting the ice that was everywhere, I made it to Lowe's. What a waste of time.

Even stopped at ACE hardware and the same story. I think I may try one of the local Hardware Stores that is not a chain and see what they have. Then there is TSC that is a farm supply store. Maybe something there. If not, I've built most everything for this oven, guess I can made the latch too.
Reworked the hinges today, as I didn't much care for the way the door was acting. It shuts better and more flat. Found I had a little bit of binding going on.
Tomorrow will be busy doing a three duce manifold and gas tank for another. Plus work on the oven as much as I can.
