Older PM 66

Hello,

I am in the market for a new-to-me Table Saw.

There is one for sale near me that has peaked my interest. Its a 5HP 3-phase PM66. The seller claims he can start it up in his garage to show me it works so I'm assuming it comes with a VFD and that would save me $2-300.

From the seller: "5hp, 3 phase cabinet saw in excellent running condition. Extended outfeed table and fence system. Not pictured is the safety attachment and vac arm. Multiple table inserts, incra miter sled, dado blade set and extra 10" blades included in price. Everything works as it should with no issues, noises or vibrations."

How old is a dark green PM 66? I've not seen the plate yet. I'm supposed to look at it next Wednesday.

Thank you kindly for your time,

The phase converter might not come with it.

Powermatic went from green to gold sometime around 1986/87. I believe the green models were made for 20 years previous to that. That is a very nice saw.

Way I look at older PM or Unisaws is " I have an old Camero,its 67" what I am saying is if no casting are broken and no issues with the tilt or up/down movement then your good to go. The motor can be replace,starter(if still in place) can also be replace so if price is right go for it.
Todays saws can't hang with the vintage saws,all made over sea's or most of the parts are made over sea's and to much plastic.

Old WoodWorking Machines is the source I go to with questions about these sorts of old machines. They have forums for woodworking and metal working machines. Their main rules for discussion are 1) no asian tools and/or 2) over 20 years old or no longer in production.

I have a 1960 PM 140 bandsaw that is that color green. I also have a 1954 floor model Delta drill press and a 1943 bench model drill press. I once had a 1990s Delta Unisaw table saw. I got all kinds of help there. Just last December, I was able to source an original drive pulley for the 1943 DP there.

My 1941 Rivett 1020 metal lathe, which is my avatar photo, was once featured in their annual woodworking machines "Calender", highlighting unique and outstanding restorations and machines. I had done some wood turning on it, but they were so impressed with its restoration that they waived the rule that year that machines in the calender had to be for woodworking.

Do you NEED a 5 hp machine? If not why go to the expense of owning one. I have been perfectly happy with my 1 1/2 hp machine for the past 35 years.

As George says, whether it is sitting in the next town, next door or the store; nobody "Needs" a 5 HP table saw. But when it is sitting in your garage or shop it is nice to have a 5 HP saw.

If it were me, I would replace the motor with a 3 HP, single phase motor. For everything that we do in home workshops, I've never noticed the need for the two additional horses. I will admit that when I bought my UniSaw, I would have bought a 5 HP model but the marketing deals were only on the 3 HP version at the time. A 5 HP model would have cost me almost double what the 3 HP did.

And like George, I built a lot of cabinets using a 1 HP Jet contractor model.

I can say this about the Power Matic saws. They are very solid and top quality. At school I used a PM that was in the 25 to 30 year old range. Absolutely NOTHING wrong with the saw. It had been serving students well for all those years. It seemed that the PM was a bit clunky when compared to the UniSaws. It is hard to describe but it was the longevity that was designed in to take the abuse of students.

I bought a PM66 new in 1990 with 3HP single phase motor and it's a great saw. I cut 8/4 Walnut and Maple in one pass without the motor giving even a hint that it's cutting something hard and thick.

I heard from the seller last night and he apparently does not want to sell.

I had seen the ad for weeks as he was asking $1,350. I thought it was a little high. He lowered the price to $1,200 so I contacted him and I was supposed to meet today, Wednesday 4/1.

He texted last night that he does not want to sell because he wants a sportbike (?).

I went back online to see hes now asking $2,000 or trade for a bike.

Best of luck to him. :/

At least he was up front about his bait and switch reasoning.

got my dream saw!

Well well well ... I got a different PM66 saw. Its on the back of my truck. I'm just waiting for my neighbor to get home so we can unload it. My wife wasn't able to help.

It's a 1989, PM66 5HP 3-phase Baldor motor, 52" fence. And I got it for under $1k ($990 to be exact since we had $10/lunch on the way to pick it up).

I'll be doing research on phase converters. Calling different phase converter manufacturers and I'll update this post as this information may be valuable for future woodworkers.

The saw comes from a cabinet shop that closed its doors. It was lightly used for a few years as the shop did not make money and they shut it down.

Pretty excited right about now.

I've been using TECO FM50s on my vertical mill and metal lathes for 15 yrs. Never had one fail or give me any trouble. Easy to wire. I've only been using smaller HP ones, 240V input. TECO doesn't appear to make the FM in 5 HP, or their product line has changed to not look the same. Here is a link to one supplier that offers quite a range of makes.

The one I've been using can be wired without external controls or with. I've been running external ON/OFF and with a potentiometer, speed control, from 0 rpm to overclocked 120 cycles (double the nominal AC 60 cycles. I have also installed installed these TECOs on friend's machines and my "source" has five or six in his shop that he's been running for more than 15 yrs. He leaves his on all the time. I don't like that, so turn mine off when not in use.

You may not need/want the variable speed control, so the external controls may not be of interest. These generally do not like to be controlled by the machines ON/OFF switch, but rather one that works connected to the terminals on its circuit board. In the case of these TECOs, that external switch is a very common single poll toggle switch, low DC voltage. Look into that aspect when you are searching. In my applications, I'm using double pole ON/OFF/ON for Forward/OFF/Reverse, which you will likely not want.
