I got this off a craigslist add a few years ago.

It’s old school with oil bath bearings.

And tracking adjusters on both sides of the idler roller.

The disk sander table has a really terrible angle adjuster, a screw wedge, but it also has two support arms that help lock the table in position.

It has worked well for me although the belt has a tendency to drift.
The problem was pretty bad until the rubber sleeve on the idler roller disintegrated due to dry rot.
I decided to replace it with pieces of an old 3×21 belt sander belt that had come apart.

That has reduced the belt drift quite a bit, probably because the gap acts as a self-center.

I have seen these machines, they hold up very well. I wonder if a hose manufacture would be able to make and/or direct you to a good place to obtain one

-- Norman - I never never make a mistake, I just change the design.

Norm,
Thanks for the suggestion.
The sanding belt works great.
I miss-identified the roller in the initial post as the idler roller.
It was actually the drive roller that failed (see photos.)
When the idle roller dies I’m going to replace it with sander belt as well.

Looks like a pretty solid piece of machinery. I have a disk sander about 3 or 4 years old and the table adjustment isn’t that great on that one either, so I think you’ve gotten a good tool there Pete.

Thanks Stefang,
If my research is correct this was made in the ‘40s.

PASs, your machine is a dead ringer for mine, except for the blue color. Mine is a Sears & Roebuck (aka Craftsman) model 103-0803. I have a belt drift problem that started suddenly after many hours of operation.

I found the owner/operator manual and parts list here: https://www.manualslib.com/download/497423/Craftsman-103-0803.html

It was free, lots of places charge for these things. Trouble is, they recommend lubrication but don’t say where the lube goes in. Is it under the capscrews that sit at 45 degrees?

FarmerintheWoods. If you look at the second and third pictures you can see a couple of plugs with knurled tops. Unscrew those and put a couple drops of oil in the holes.
