I am progressing on rehabing my old Craftsman table saw. The cast iron table was pretty easy to clean up. Next, I would like to clean and lubricate the moving parts that need lubricating. The blade spins but it feels like there is some dried grease or oil binding the shaft a bit. Does this mechanism have sealed bearings by chance? Also it is not obvious how to hold the blade or shaft when changing blades. There is a dual belt pulley on the shaft that turns the blade but no place to hold the shaft with a wrench that I see.

I cleaned the fence and lubricated the the adjustment parts. The fence seems to lock down OK and appears to be square to the blade but I noticed that the non-adjustable end of the fence may be missing something. There is a small piece of metal that swivels that has a hole in the middle that may have held some material to help lock the fence. Or maybe it was designed for a metal to metal fit. I still have not located a serial number.

Any comments are certainly appreciated. Thanks

Hi Bigbird

I have a 1938 Craftsman table saw that sounds like it had the same issues as yours before I restored it. The bearing in it were sealed bearings, but there was a lot of crud that got into the mandrel and was causing it to bind up a bit. I had the same problem on changing the blades. I use a vise grip on a towel over the blade, with the junction of the blade and the vice grip resting across a piece of wood across the table top. My thoughts were to do that so that there wouldn’t be any offset force against the blade. The only force the blade is subjected to is circumferential. I only use it now for dadoes as I have a new 10” Hitachi.

Do you have a picture you can post? I had another Craftsman saw that was 50-s vintage that belonged to my dad but my brother has it now.

Hello Sam,
I am going to take some pictures this week-end hopefully. Maybe someone can identify the model. Since the shaft that turns the blade has a dual pully and the old electric motor has a single pulley, I may have a “parts” saw, i.e. parts from several saws. No matter, I think it will be the ticket for what I need for the current project.

I found a manual reprint that shows a block of wood being used to render the blade stationary for removing and replacing the blade. Makes sense.

Here is a picture of the model of the Craftsman saw I have. This is a photo I found on the web not my actual saw. This one looks like the on /off switch was converted to a single pole type. would this be from the 1930’s or so?

Even if the bearings are worn, these are easy enough to change. Like Bill commented, when you have it working good, it is a keeper.

If that pic is a likeness to yours, it exactly like mine. A 1954! It works just fine, clean it up and you won’t be disappointed.

Does anyone know where the serial number would be on the 1954 model? Do you know if this saw was originally made for an 8” blade? It seems to work fine with a 7 1/4” blade which is big enough to rip standard 2” finished lumber. It did a good job on some Costa Rican Christobal 1” x 6” tonge and groove paneling. I’m happy!

Craftsman saws from that era did not have serial numbers, but the model # plate was attached to the lower left hand corner of the base when looking from teh rear of the saw. I also beleive that your saw is meant to be an 8” saw.
