The DoAll 16" LHF Bandsaw, Part 4:
The only damage was the central shaft, which had a bronze bushing mating the input and output ends.
This had gotten moderately scored, as the gearbox had been run at least some time without any oil at all-
the roller bearings took the abuse easily, but the bronze plain bearing took some scoring.
It was a fairly
simple repair, starting by chucking up the shaft and indicating on the bearing boss.
I couldn't indicate on the outer stub of the shaft, as it turns out the shaft has been repaired before-
besides the rough file marks left on the OD for some reason, the bore had been sleeved
before having the bronze replaced.
But the bearing boss was true enough, and I was able to bore out the old bronze.
Turn the new chunk to a .0015" interference...
And press 'em together.
Bore to size (0.003" over the shaft size) and face to length.
And finish off the existing notches with a Woodruff cutter.
And done. Note the bright ring of the previous repair sleeve.
