Just picked this up at an auction for $50. I swore to myself no more machinery til I get the garage electrical remodel (waiting for electrical buddy to look over my work before calling inspector). But I could not pass this up. I did need a disc/belt sander. Was really leaning towards the $200 Ryobi oscillating sander. But this called my name out loud. I love the black cast iron, no plastic anywhere. I’ll have to get a motor for it. 1/4? 1/2HP? More HP = less slow bog down, right?
According to vintage machinery, this is early 1940’s Sears-Roebuck 103.0803. Gotta clean it up and make it all perty

what motor do you have on it? I was thinking of “sharing” my 220v Jointer motor (a poor man’s version of a Shopsmith). But then, I never bought motors before so am at a loss at what motor for what machine.

Holbs, I picked up a slightly more recent version of your sander. 6×48 with a 9” disk, right? Mine had a 3/4 hp motor and I’m happy with that but I wouldn’t want anything smaller.

Oh, and it’s 3500 rpm with what looks like about a 1:1 pulley ratio.

when you say 6×72… are you meaning 6”wide by 72”long?
oh no… not this thing. more like 6”wide 24”-32” long.

I mean that would be the belt size you’d need. My belt bed is about 22 inches long but it takes a 48 inch belt.

mule… if you have something similiar… do you find it better than the $100 delta shopmaster china made stuff?
that is my hope in this: cast iron, metal EVERYTHING, with a robust foundation.

snowy: this reminds me of my great grandmother’s SINGER sewing machine :) the cast iron black (in spots that i see under the rust) look… beautiful. ancient history in that there iron

Oh yeah! I’m really pleased with it. I got it on a fluke for 30 bucks. I’d looked at the plastic crap at HomeDepot and then quality stuff that ran about $400. I didn’t think the cheap stuff would satisfy me and I couldn’t pull the trigger on $400.

I have a table saw, jointer, planer – all solid cast iron veterans.

that link you sent…. you look to have something nearly identical to my workbench. and yea, our sander’s look to be the same dimensions. does your sander bog down?

I can bog it down if I bear down on the workpiece but for my normal uses I couldn’t ask it to perform better. I thought yours looked about the same as mine. Measure axle to axle on the belt drums – if it’s 20 inches you’ll take a 48 inch belt.

I wish that work bench was mine. That’s one the gal I got the sander from had advertised on Craigs List for $100. Of course by the time I got there it was gone. The table saw in the picture is the same as mine except I have a upgraded fence. She was selling that for 75 bucks. I would have bought it for one of my son-in-laws but of course it was gone also. What I was after was the scroll saw which I later learned was a premium saw, 50 bucks for a saw that probably lists for 500+. Missed that by about 30 minutes. The sander was balm to my disappointments.
