Topic tags/keywords: tablesaw motor question tablesaw

Hi everyone , I recently inherited an old delta uni-saw from my great uncle . Its in great shape except the motor died on me shortly after I got it . Do I buy a new motor or can I have it rebuilt ? The saw is dated around 1949 – 1954 , and it has a huge 1hp 230 volt motor . Does anyone know of any sites that deal with tablesaw restorations or motor rebuilds ?

Any motor shop should be able to rebuild teh motor or sell you a new one.

Yes get it rebuilt, just as good as new.

OWWM is my source for old tool restoration.

Unfortunately they do not have a lot of info about motor repair. They do show some details about disassembling motors to replace bearings, fix starter switches, etc.

Motors are hardy beasts, particularly older ones like yours. If they are capacitive start, the problem is most likely the centrifugal switch that removes the capacitor after start or the capacitor itself. These repairs are easy. If, however, a winding in the motor has opened up or become shorted to the case you best bet is to find a decent shop to rebuild it.

There is only 1 site.…....You can narrow down your saws born on date by going here

If your saw is in the date range that you have given , your motor is most likely an R/I, repulsion induction, motor. There is a lot of info and discussion on those motors at OWWM. There is also a discussion forum located at and a forum for parts as well. I do have to warn you though, the skope becomes very slippery.

I have a unisaw that was restored and the site was a great deal of help. Be prepared to post pics, they are a weird bunch and love pics.

Ditto on the OWWM site. I did run into one person there though that ruined it for me. I don’t go there except for info. I got into the forum but after being treated like I was I don’t go anymore. So be prepared for the people there. So ask questions but be careful with posting. I have rebuilt tools for over 30 years and prefer them to new.

Might pay to check with a Delta dealer in your area. If they don’t rebuild motors, odds are pretty good they can point you to local machine shop that can do the job.

My experience with OWWM is different from that of willy3486. I’m rebuilding a Delta 40-440 scroll saw and got to a point where I was pretty sure something wasn’t right but I didn’t want to break anything forcing the issue. I sent emails to several folks on the site that had rebuiilt similar saws. Within an hour, I got a call from a fellow in Canada that talked me through the issue and then demonstrated (via Skyp) on his own saw how this particuloar part of the saw worked. To say the least, I was extremely appreciative.

First congrats on the sweet saw! Second go to OWWM as many have suggested. You can also call Delta’s customer service with the serial numbers and they will have some info for you. They keep an extensive library on all their saws.

For the most part the OWWM site is good. There is one guy there that is really helpful, I think his name is Bob Vaughn. I ran into many that were as you said very good to deal with. But like I said I ran into one person who was very rude and I have not been back. That one person really burned me and the sad part is I have a lot of knowledge on these things and could offer it. I also have access to a lot of company info. I have found some of the members there that were good to deal with on other sites and I go there. That way I don’t have to deal with the ones I don’t want to. I wish the site well but I don’t go there myself. By all means if you need something check them out they have a lot of good info and many will help. But be aware there may be one or two that may burn you like they did me.

Have your say...
