images named saw_shaft_repair 001, 002, 003, 005, 007 are photos of a damaged shaft 
repaired using TIG brazing with silicon bronze filler.
This shaft is the upper wheel shaft on my 20" Delta woodcutting bandsaw.
The inner race of one of the bearings was allowed to spin on the shaft, scoring it badly.
