The pour

On March 27th 2014 Jeff Campbell, Roger Shull and Julia Land met in my garage for the babbit bearing pour. Jeff loaned us his turkey frying propane stove and Roger loaned us his cast iron pot to melt the babbit. This set up worked very well for melting the babbit. It only took about 15 minutes for it to be completely molten. Meanwhile, I used a torch to heat the frame of the gristmill in the region of the bearing journal.

I did the pour and the bearing filled up. I used a clay for damming up the ends of the journal to keep the babbit from running out. The clay and babbit did have an undesirable interaction but the effect was minimal and limited to some minor bubbling at each end of the bearing.
