Topic tags/keywords: tablesaw powermatic is it worth it

I am selling my chainsaw (Husq 394xp) and the accompanying milling attachment in order to get some money for a new table saw or planer (I currently have crappy versions of both). One guy has contacted me with an offer to trade for a PM72 that is reportedly in great condition if I am willing to also throw in $200, which seems like a fair price if I compare it to other PM72’s on craigslist.

I would love to have such an awesome saw, even if it is overkill for my skills and the kind of projects that I am doing. My issue is that I would have to throw in $200 and then buy a phase converter, VFD, or new motor. So I am looking at being out my chainsaw and ~$500 before I even get to consider new bearings or riving knife or whatever it may need.

What are your thoughts on tool overkill and value of the PM72?

I had one along with the Delta version. It is a really good saw. Keep in mind it has a 1” arbor, blades will cost a bit more but, the solid nature of the machine about 900lbs and 12” blades makes for some nice sawing, 5” depth with a 14” blade. The one I had was 3phase 5hp, I ran it off a rotary phase converter that I run my other heavier then consumer machines. The 72a was left tilt, right tilt works better for me, so I kept the Delta 12-14.

Yes… 900 lb. I think I would definitely be borrowing a truck and trailer in order to get it here. The motor on this one is also 3 phase 5hp.
Do you know if it would it be difficult to find a single phase motor that I could fit onto the mount? Also, in your opinion, does it need 5hp to drive a 12” blade, or would it be feasible to use a ~3hp motor in order to lessen the draw on the shop circuit?

Id do it. The deal I made for my unisaw was horrible compared to what you’re getting.

It appears the saw was available 3hp single phase. The motor is a face mount type, so yes another motor could be installed, but it would be better and less costly to use some type of converter and use the original motor and control.
I so far haven’t used a VFD, folks on the OWWM forum have used a 3hp VFD to run the 3phase 5hp motors in these saws, I think it was said the cost was around $150….I would poke around there for more info, such as power requirement….seems a 30amp 220v is needed.
The saw itself is well built, and easy to work on and adjust.

Thanks, Bob. I looked at VFDs, but I was looking at 5hp versions, which got pretty expensive. I’ll do some research on OWWM.

On a fairly recent post on the Delta 12-14 “OWWM”, one of the members named the 3hp VFD he has been using.
Table saws don’t have much start load, so the lower hp VD appears to work well.
There is one thing to consider on the larger saws, the distance to the blade on the PM is 17” from the front edge. Some folks that are shorter may have a harder time reaching that increased distance. Myself, 6’ with longish arms, its just right, but my saw is sitting on the floor. With a mobile base, the height is a bit too high for me, reducing reach….On that, I never place myself in front of the blade, so I need to have the reach.

Just got the pictures… yeah, I think I’m going to go for it.

You won’t regret it my friend. You’ll just need to remove that inverted channel from the wing and go to work. (That was likely supporting a Brett guard). That machine is worthy of installing a single phase motor for sure. You will be able to use the existing controls with it. Don’t get too caught up in the Mickey Mouse stuff like a Irving knife,etc. Just learn how to use it . You’ll never need another ! Enjoy! jB

The deal is done! I traded the chainsaw, milling attachment, and $100 cash for a powermatic 72, manufactured in the USA in 1980. It came with a 5hp 3phase motor, 48” beismeyer fence with 80” rails, the original splitters, and legs for an extension table.

I’ll need to get a new motor or a phase converter, but considering that this cost me $700 (counting what I originally paid for the chainsaw and mill) I think I’ll be able to get it all done.

Sweet deal! Great fence! Great Price!
Ha Ha! Look at what $700 will buy in a new saw…..Not even a hybrid poodle saw!
