RE: Building two under influence of ... (in reply to estebanana)

The table was rusted, it’s since cleaned up well. Now I’m engaged in rebuilding the motor. I pulled the three bearings off of the motor shaft and differential gearbox. The bearings were worn and clicky, screaming horribly with motor on. I hope new bearings quiet the motor and address the vibration. With the belt and the blade off the saw vibrates with just the motor, I think the wobble in the bearings is being amplified and is vibrating the frame.

It’s a diversion I can’t really afford, but then right now I can’t afford the brand new band saw I really want.

Nevertheless already into the next group of necks and new commissions- only sorry my original intent to compare the Conde design has become a lesser priority.

This one f-ing bearing is holding up the completion of this band saw refurbishment.

It’s 26mm by 12mm and the bore hole is 9.8 mm

Why on earth does this need to be a motor shaft that’s 9.4 mm ? What the F was wrong with 10mm?

You can get any non oddball bearing at a hardware store, but this bearing doesn’t even show up in a catalog database.

The manufacturer Koyo makes bearings for automobiles and electric motors and scientific equipment, but no they don’t make this one anymore. So I wrote to them and asked if there is a modern equivalent.

9.8 mm is vary close to 3/8" perhaps try to source dimensionally in US units?
