Jointer progress

Link to here:

Update to the jointer being rebuilt, picked up replacement bearings and pulleys this afternoon, now cosmetics will have to be finished for assembly . With the old motor being junk, a 110/220v Leeson motor will be used. It came with a small flat belt pulley, and the old cutterhead pulley was a dual with a piece missing, and keyed and screwed to the shaft.
Needing the cutterhead to turn at just under 4000rpms, the new compression hub pulleys are more secure, better balanced and with their increased weight will contribute to overall smoother operation. New offset bearings were sourced, 7052 and 7053s are common, but built in the 40s this unit used a slight offset. Shims could have been used, but OEM are always better.
