SB-9A Banjo
« on: October 30, 2020, 08:43:21 AM »
The replacement banjo and idler gear I bought to repair my lathe were delivered yesterday evening.
The one difference I noticed between the new banjo and the old one was the old one had a set screw in it to help lock it in place.
After looking through the South Bend lathe parts manual copies I have, I didn't find a set screw listed for the banjo. Got to wondering if the set screw was an OEM piece or if a previous owner had installed it.
Anyone know if South Bend ever manufactured them this way ?

I'll be heading to the shop soon to put the new parts on. I'll take a picture of the old banjo and you can see where it cracked, right across the center of the set screw hole.
I plan on doing a repair to the old banjo, but wasn't sure if I should fill the set screw hole or re-drill and tap it.
