This was my Dad's. It is a Craftsman King-Seeley probably around the 1950's anyway. Floor standing. It is good machine that I have used for a long time. However, it has never had the power that I think it should and I believe it is due to the belts. This has come to be a problem as I want to drill a 3 1/8th inch hole for a clock in a hunk of maple 1 1/2" thick. It just is taking forever. I don't really know how to work the belt system. There is no Sears part number on it that I can find, but it does have a 1/2hp motor.



Here are some pics:

If you have any idea what I do to minimize the belt slip, that would be great. Thank you.

This is the exact system with the belts I need:

Good find...I presume you saw the picture links I posted earlier...

Are you sure you really need new belts? They don't look worn in the
pictures; while old unless are glazed surfaces or obviously worn I'm
guessing they're not going to make much difference.

Since the press is pretty old and it mentions these are packed bearings,
have you checked all them for being well-packed w/ non-dried-out grease
and that the speed adjusting pulleys operate, etc., etc., etc., ... ?
What about the drill spindle bearings too?

On the belts themselves, I'm guessing the numbers are lengths in tenths
of inches -- Measure the width and depth; there are standard A, B, C,
.... cross sections for v-belts. A is 1/2", B = 21/32", etc. Automotive
belts use a NL nomenclature where N is 3,4,5,... and is in eighths of
inches. So a 4L is equivalent cross section to a standard industrial A.

If you think you really do need to replace them go to the best-stocked
NAPA or other automotive parts place you have and match them. They'll
have a belt-measuring device to make it simpler.

Not so likely the short lengths OP needs ime...on hand, anyway.
Undoubtedly they can get/match anything made but the auto supply tends
to do better for smaller stuff owing to all the configurations. Altho
w/ the advent of the serpentine perhaps not as much as in days of yore.

That's not to say don't try, of course--what is common in one location
ain't necessarily the same somewhere else. Probably greatly depends
also on the type of farming in an area--this is large grain production
country where stuff is on very large scale and not much if any small
producers or hobby farms that tend to have utility-sized stuff...

I'm sure it depends on the place but the one that I used to go to even came
up with a belt for a 1948 Singer sewing machine.

Yes, you're right, it would be quite location specific. The place that I was
talking about was in a place that had many small orchards hence small
machinery.

There's a place like that here, too, but it ain't one of the farm supply
places...
