Topic tags/keywords: table saw delta unisaw rockler

I currently own a 1987 Delta Unisaw I’m considering selling but I’m having a hard time finding one that is a 10” that has 7.5hp. It’s in really good condition with a biesemeyer fence and attached table. I have a 2 car garage that I have my shop set up in and I don’t think I need that big of sawesome, so I’m considering selling it…..but I’m having a hard time determining a value.

Does anyone have any knowledge on this saw? From what I know about it, it is a complete workhorse and a very sought-after saw.

Any advice is very much appreciated!

It varies by location, the best guide is to look through Craigslist and see what others are trying to get for theirs.

Tough call. 7.5 HP is a deterrence for a hobbyist. Also is it 3 phase ? That would make it even less desirable.
So your best bet would be to still find a commercial shop foolish enough to buy a used equipment. In my area commercial wood shops were all but phased out by low quality mass production so that is not easy too.

I would guess you cannot lift a 7.5 HP motor by yourself. When I bought my Unisaw I moved it myself by taking it apart. My Unisaw had one of the old Rockwell 3 HP motors built by Baldor. I think it weighed close to 100 pounds. I would not have been able to pull out a 7.5 HP motor by myself.

Wow… I don’t think I’ve ever seen a Unisaw with a 7.5HP motor, although they were pretty common on the RT-40’s and 12/14’s. Can you post some pictures? Also, are you referring to the saw being to big due to the motor or the physical size of the saw?

If it’s 7.5 HP, I’m thinking it’s probably a 12”
I’m looking for another table saw. If you do want to sell it I would like to see it.
Also would need to know where your at.

What do you plan to do that will require 7½hp on a 10” saw? I have a 5hp that I occasionally run big gnarly stuff through and it has never struggled even a little.

I doubt the bigger motor will increase the value of that saw. Could go the other way! If it is a 10 inch unisaw, price it like other 10 inch unisaw, and hope the prospective buyer can live with the monster motor.

Yes, it is a 3 phase and I double checked and it’s a 10” blade. Long story, but I ended up with this saw and I was going to wire my garage to handle this type of saw, but the more I thought about it the more I’m thinking it’s just too much of a saw for what I really need it for.

Jbay – Yes, I’m going to sell it, but I’m trying to figure out what price would be fair on this. I am located over in the Portland Oregon area. Are you anywhere close at all?

Three phase reduces the price, particularly if you have a 7.5hp. Post a picture or three of the saw, and maybe a picture of the motor data plate so the electrical requirements can be determined. Serial number badge would help as well.

I’m the type of person that might be foolish enough to spend money on a used Unisaw.

Around here the Craigslist prices seem to go from around $400 for a decent looking condition saw with no fence but a three phase motor to over $2,000 for a saw with lots of bells and whistles, single phase motor and in nice shape. Most seem to land in the $700-1,000 range with three phase because the people with single phase seem to keep them.

I would look to buy in that $400-700 range and hope that I can find something that is priced low because of an easy to fix problem or a seller that doesn’t know what they have.

Three phase is a problem. Very few people outside of industrial areas even have the option for three phase electric service so almost every buyer would have to budget for a 7.5 HP phase converter. I’m pretty sure that would be $$$. I bet that is a big reason why you want to sell.

If you wait long enough for the right buyer, you might get $1,500.

Alternatively, you could look in to a 3 HP single phase motor retrofit or part it out on eBay.

Have your say...
