Topic tags/keywords: question tablesaw craftsman

We inherited a fair number of tools from my husband’s aunt that had been sitting for years and years. One of them was a Craftsman 113.12171 contractor table saw. I’ve been told that belt driven saws are the best you can get, so we were hesitantly excited to bring this one home. We thought we checked it over carefully before we fired it up, but I guess we weren’t careful enough, because by about the 3rd board the motor quit. We found a replacement motor for a small fortune on Grainger, a couple of used ones for ~$100+ on eBay, or a new Ryobi/Harbor Freight saw for around $200.

Should we get a new/used motor for this saw? Or just junk it and buy a cheap saw from HD/HF? We’re not hardcore cabinet makers or anything, we mostly just build stuff for around the house and do home projects. I liked how smooth and quiet this saw was for the whole 10 minutes we used it, but not sure if it’s worth trying to save for the long haul.

I suppose I should also mention that the fence is terrible, the top is kind of rusty (but I think it can be buffed out), and we’re going to need a different stand, but if it’s a great saw that’ll run forever we don’t mind. :-)

I’m attaching a picture of the motor, for whatever help that might be.

Thanks!

You might find a local shop that will repair the motor. You can also do a Google search on a 1 Hp 3450 rpm motor.

I wouldnt bother fixing a saw that is in sorry shape and you don’t even really like. Look for something else on Craigslist. You can probably get a newer Craftsman 113/315 on craigslist, with a modern fence, for $150-200. Or look for an older Delta contractor saw.

If the motor didn’t start smoking then it’s more than likely another problem. Cap, centrifugal switch, or start switch.

A razor blade scraper will remove more crap from the top than you might think possible. Then a scotchbrite pad to get the dips and miter slot, clean up with a solvent (mineral spirits, etc) and wax it or put on whatever rust preventive coating you like. Do worry about getting to bare cast iron. Leave the patina. It’ll help protect against corrosion.

if the motor ends up being good then just find a new or used fence to put on it.

I’m finding a few with a “56 frame”, but my current one says that it’s a G56Z frame. Are they interchangeable?

How did it ‘quit’? Did you try to turn it on and it just hummed? Did it quit in the middle of a cut? Is there any indication that it is trying to run at all? Most motor problems can be attributed to fairly simple problems to fix… you just need to figure out what it might be. Unless it needs to be rewound (rare), it should be salvageable. Given that it was running previously, it most likely is still good. You didn’t let out the magic smoke did you? :)

I was thinking something along these lines for refurbishing the top, but it’s always nice to have someone else reinforce your thinking. Thanks!

My husband thinks the bearings went out. Mid board, the blade suddenly stopped, but the motor still hums. No smoke.

If it can’t be fixed, I will keep this in mind—I never think of Craigslist for anything, but maybe that’s just because I’ve never found anything I’m looking for on there (yet!). Thanks!

And yeah, the old Delta contractor saw I borrowed from an old contractor friend was pretty awesome—that’s what made us so excited when DH’s aunt said she had this one. :-)

Bearings are a pretty simple fix if that is what it is. Certainly a possibility given the age of the motor and the fact that it has not been used in a very long time. Try taking off the belt and spinning the motor by hand, as that will give you a pretty good indication if they are seized or not. Since you have already basically written the motor off, it certainly won’t hurt anything to open it up and see what is going on. Give it a good cleaning out, check the bearings, clean up the contacts on the centrifugal switch, etc… also, grab a multimeter and test the capacitor while you are at it. Can’t tell from the data plate, but does it have one (start) or two (start + run) capacitors?

Chances are, you are looking at just a few dollars to fix, rather than several hundred to replace.

Cheers,
Brad

I will have my husband take it apart when he gets home, because that would be pretty awesome if it was fixable. The trick might be finding parts.

Thanks!

The only parts you would probably need is bearings and/or capacitors… both are off the shelf items that can be found easily at numerous places (other than Sears :)

Simple test: take the pulley off. Try the motor…..shaft turning? May be it is a pulley problem. They are held on with two set screws, and a keyway piece. IF one screw was missing, the other gets loose, and the key stock wanders out of the pulley. Check BOTH pulleys while you are at it.

I can’t tell from the plate itself about the capacitors, there’s certainly enough space for it to have had the word “run” in there at one point, but the sticker has peeled off and turned black in that spot. Sorry.

You guys are awesome! I’ll have DH check this stuff when he gets home and we’ll see what our options are. In the meantime, I suppose I should probably get back to the stuff they pay me the big buck…erm that I get lots of prestig…well, you know. ;-)

56 frame is pretty much a run of the mill standard motor. I’d be willing to bet just about any motor with a 56 base should work. This I only know because of minimal research and in passing while changing motors and looking for replacements.
