They have it listed at $600.

Looks to be an early 80’s model, and is surprisingly complete – only appears to be missing the blade guard and motor cover. Depending on what motor is in there, $600 is certainly reasonable, and hopefully that roller outfeed table comes with it. Figure on another $100 or so for bearings/belts and perhaps new wiring.

Cheers,
Brad

The older Unisaws were great saws. I also thing newer Unisaws aren’t half bad either (but others would probably disagree). I agree that $600 is fair, but you might see if they will bite at $500. And if the rollers aren’t already included, get them to throw them in for the price of $600.

I was just curious, it seemed like a good deal to me. But a saw like that would be well out of my price range. If anyone in the Virginia area would be interested in it, here is the listing:

Is it single phase? If it’s three phase, $600 is steep. If single phase, $600 isn’t bad. I’m not a huge fan of the round fence rails, but they’re certainly serviceable.

3hp single phase per the listing…. would be a good price in my area (not the same area as the sale)

Our machines looks quite similar. I got it for $600 too.

Mine has smaller motor (2HP single phase), but came with magnetic switch and 52” biesemeyer.

Looks identical to mine, except I have a 54 inch rip capacity and extension table.

Mine has a shop made motor cover (plywood) courtesy of the prior owner. I had new arbor bearings put in mine when I bought it over 20 years ago. It’s been flawless since. Mine has the blade brake. It stops just a few seconds after shutting it off, which IMO is a huge benefit.

I think I paid $900 for mine from a local dealer—was a trade-in. A lot of money back then—1995? They put the new bearings in it for me.

I’d pay $600 in a heartbeat for that machine.

600$ is good. Less is even better of course.

I just picked up a ‘59 complete but miter gauge for 450$. A steal around here 3ph or not. Vfd was 80$. You can get a Chinese vfd for 100$.

THE blade brake. The motor stops the blade in under 5 seconds after turning the motor off.

Then it is a well kept secret by Delta :)

Now… if you have a 3 phase motor and VFD, that’s a different story!
I would love to hear more about this blade brake you have.

Electric motor brakes are available. I’m
not aware of that being a stock item on
a unisaw but I’ve seen them installed on
industrial saws in auction listings a few
times.

Some newer saws like Felder have electric
brakes standard.

Yup… they are out there – typically DC injection on a single phase motor, but as you mention, not a stock item. The reason I inquired is a lot of people hear the centrifugal switch closing, which does slow the motor down, and believe it’s a brake.

Cheers,
Brad

PS: 5 to 7 seconds is a pretty typical stop time on a table saw.

Looks like a solid machine for a fair price.

I think belt drive table saws stop a lot
faster than old direct drive ones. I have
a Tannewitz that spins big blades and
it takes a long time to come to a stop.

OK, I said it was a blade brake. The blade stops very quickly, within a couple seconds. I can’t say for certain that there is an actual brake as I’ve never looked for it. Maybe I should have said motor brake, not an actual BLADE brake, though the effect is the same. I hear a thump a second after shutting power off and then the blade stops. It’s 3 hp, single phase. What ever it is, it acts like a brake.

I’ve had direct drive and belt drive saws before. They all took much longer to come to a stop.

My saw did that for awhile, and then I realized the bearing was on it’s way out. Never made the bad bearing noises, but stopped pretty quick. That might the what’s happening. Rotate the blade by hand to feel for any resistance. ... Jerry (in Tucson)

Mine has brand new arbor bearings and the blade still stops within 5 seconds or even faster. I think it’s the belts that absorb the energy. The less belt I install the longer it keeps spinning after switched off.

One thing I noticed when I replaced the start capacitor last week. With the old capacitor my saw ran fine, just a bit slower to start, and the motor kept spinning like forever after switched off (belt removed). After installing a new capacitor the start up is no longer sluggish, and the spin down is also a lot faster almost like there’s a brake in the motor. I don’t understand why.

New bearings. Been acting this way for 20 years. I suppose it could be the belts absorbing energy as they flex around the pulleys. It has 3 belts.
