I measured the circumference for the belt and came up with 28", but now that I've read the ad, it's a 26 3/4" belt. Gonna have to dig to find some of those.....and I misspoke, it's a 3" belt an not a 4". I did get the oiler things figured out and found out that opening the ball port with a skinny scribe and drizzling 3 in 1 oil a drop at a time was a method to get the oil where it needed to be. The top roller wasn't too stiff, but the bottom front one was almost locked up, so I worked it gingerly and eventually butted it up against my long bench mounted belt sander and let it spin it at "working speed". Both bottom rollers have some sort of friction tape on them and I was wondering if that was factory, or some sort of grip or protection for the rollers? I'm also wondering if I should remove it. Took the gear cover off the other side and man, they really packed the grease in there on those drive gears. Would it be to may advantage to replace that grease after 60 years of use and dormancy.
It does have a previous owner's name engraved in it, so it's collector's vcalue isn't much, but it's still a really cool sander and it was great reading Sears' hype on why you should let go of a week's pay to own one.
NOw that all of the rollers are relatively freed up, it's time to find that oddball sized belt.
