OK, so I get excited and even gloat about our CL finds. I still heavily support acquiring old iron off of CL. But one trade off to employing a 25 year old piece of heavy equipment, in this case an 80’s model Grizzly 3 hp cabinet saw, is that you might have to purchase a motor like I did today.

So my motor burned up, I went to my motor guy, he confirmed as much. The closest he could come to replacement was a Leeson motor used for the Unisaw TS. But at the cost he quoted me, 550.00, I opted to go to Grizzly to get the replacement motor, which is 340.00 shipped to our home. My guy could have completely rebuilt the old motor for 475.00 but I figured if the Grizzly motor lasted 25 years, then the replacement grizzly motor should outlast me :).

A question though, I noticed the motor does not have a thermal overload reset on it. Is this common for a motor on a table saw. I installed a brand new Dayton motor in my 20” Powermatic bandsaw this last winter and it does have a thermal overload on the motor. I would have preferred the thermal overload feature, but not complaining at all at the small price of 340.00.

So, I now have 640.00 invested in this saw. Paid 300 for the saw, now the new motor cost of 340.00. Previous owner stated he put new arbor bearings in the saw. It is actually a great saw, a real pleasure to use, well except for when the motor burned out :)

So now our shop is down to just the Unisaw and we also have a job site table saw we have set up.

Goes with the territory Jerry. Sadley it never happens at a good time! Hope you get it up and going quickly. How’s that shaper doing ? Shouldn’t have to worry about that one for a few years. JB

Hey JB, hows things going, hope your staying busy. Yeah break downs never happen at good times. I was hoping it was just a bad switch. But now with having the new motor there will be some added durability.

The shaper does great, just hums and is a real smooth running shaper. It is set up to run all of our stick and it does a great job. We can sure knock out some doors for sure. We enjoy it.

About the ts though, it was so unexpected. No signs of wear until it burned out. Wife just turned the saw on, it blew the breaker, lights flickered, she said she smelled a bad smell from the motor.

I was looking on eBay, there is a 3hp leeson sold as a replacement for unisaw, the cost is 360.00. Seems that would be a better buy to me, but I would have to cancel my order with grizzly, which was probably already shipped.

my PM66 has a new 3HP baldor and it has an overload on the motor. I personally would have gone for the rebuild. A local motor shop has the ability to put in the good stuff. Even though the old one lasted 25 years the new one probably isn’t built as good as the old one. Like I said I would go for the rebuild at the price quoted. My next choice would be a baldor, then leeson. Also if you go local you have someone to talk to if the are any problems. Grizzly you get an operator who probably doesn’t understand any thing they don’t read from the screen.

Shawn, you have good points. I’m considering cancelling the order and going with the 3 HP leeson. It is on eBay at http://item.mobileweb.ebay.com/viewitem?itemId=350687158471&cmd=VIDESC

But I would be hurting if it was somehow slightly different and did not fit the saw.

The actual grizzly replacement motor is found here, looks exactly same as unisaw motor. http://www.grizzly.com/products/Motor-3-HP-Single-Phase-3450-RPM-220V-For-G1023Z/H5387

I noticed the motor does not have a thermal overload reset on it.

Take a look at the nameplate. It will say if it is thermally protected. It maybe b e an auto reset without a push button. That is not a good idea for a saw. It could start unannounced!

Jerry, the Leeson motor you linked to states it has NO overload protection.

Funny you just posted this since i just found a Grizzly 1023s that i could get for $75. It has the motor with it but someone wrote on it that it needs a rebuild and had no fence or rails. I’m contemplating getting it and weighing the costs of getting it useable. Everything else seems to be ok.

After sleeping on it you could take some measurement of where the mounts are. Then grind them off the motor and weld them back on any sealed motor. Just a thought

If i had a welder i could maybe attempt to do that if i knew how to weld.

Hey Shawn, just an update, but I cancelled the order with grizzly and ordered a 4hp lesson online. I have a unisaw and the two saws are near identical, in fact only difference in the 2 motors is the unisaw motor has 3/4” shaft and the grizzly motor has 7/8” shaft. So I also bought a new motor pulley I was able to pick up for 34.00 from the source selling us the lesson motor. Well, I think it will work out great, got a better motor and upgraded to 4 hp. No thermal overload reset but mag switches offer a safety net.

I would buy it. I will let u know how the lesson motor works out, I’m sure it will fit. The 3hp lesson is 362.00 plus shipping and u also need to buy. New motor pulley for 35.00. I went with the 4 hp motor for 392.00 for the extra power. A fence can be an expense, 150-250. Let me know what u decide.

I been thinking of building my own clone of the beis so that might not be too much cost unless i just go with the supercooltools guy’s version since i dont weld. I do have a bunch of aluminum but would it be strong enough for the forces subjected to it?

Could not tell you much about building your own fence. I know Delta offers a decent 30” fence in the 150 range, the shop fox fence seems good at 250. But if you can make your own that might work out good at less cost. I know a good fence can make the experience with your saw a very positive one, if the fence is not so good then of course TS operations might not be nearly as enjoyable.

One thing about renovating your saw is the pride you would gain from restoring some old iron :)

I am excited to see how the new motor works with the table saw. Maybe it will be like using a brand new saw. Maybe I will have to look at building a clone of the beis then we will really have a like new saw.

And going with the 4 hp motor was really not needed, a 3 hp motor would have been more then adequate. I just figured for an additional 30.00 the extra power would not hurt.

I guess it depends on the circuit breaker amperage whether or not the extra power would hurt. Don’t want to pull to many amps and keep tripping it.
I’ve already restored a 10” delta band saw and i have a 4” jointer also delta milwaukee to restore too. I do like to do the restorations but they aren’t as complicated and expensive as a cabinet saw. Also wondering if my wife will be upset if she sees another machine that doesnt work yet in the shop. :/

sorry, welding was a second career path for me since my dad was a union pipe fitter. I have been certified for steel up to 2”, aluminium up to 3/4”, and stainless steel up to 1 1/2” since I was 20. but I decided to be a union carpenter instead. there was always something about houses and interior final finish that gave me great pride
