no previous part Part 1 of Powermatic 66 Tear-down & Clean-up series no next part

Found this 1980’s era “Gold” Powermatic 66 on Craig’s list on December 30th, 2016. There were no pictures on Craig’s List. But I got a quick reply from my text to the seller. He emailed me a picture of the saw, and I told him I wanted to take a look at it. The selling price was listed at $525.00. The information in the ad said it was a 3HP single phase 230 volt.

I went to see the saw on New Years Day and while the saw looked a bit rough I knew I wanted it and it could be re-conditioned and become my favorite tool. The saw came with a 52” Biesemeyer fence but there was no miter gauge, and no motor cover (the 4 screws were there on the side of the cabinet so it may have had one once).

The cool part was the seller threw in a 14” band saw for $50.00 and he was willing to delivery the saws to my place which was over 45 minutes away. So I ended up gladly offering a total of $620.00 for the Gold PM 66 and the bandsaw delivered the same day.

Here is a picture of the 14” no-name bandsaw:

Next time I will post some more pictures of the Powermatic 66 and begin to document my progress in my re-conditioning and modernization of my 10” Cabinet Saw.

It looks pretty clean. nice find. Have you wired it up to see how it runs?

A friend of mine found a used one in poor condition for half that a couple of years ago. He had to disassemble it completely to get rid of all the rust, and then repaint it. I don’t think you’ll have that problem. (His was red, and only 20% of the gold paint left)

Most of the maintenance on those machines is pretty basic. clean and lube the trunnions, (use paste wax, the dust won’t stick in it) Check the belts. clean and wax the top. Check your top alignment to the blade. We had to replace the motor shaft in ours a couple of years ago, (generally it runs 4-5 hours a day 5 days a week. been that way for 30 years. I doubt yours will require this.) The blade height lock on ours hangs up sometimes. I need to take it apart and clean it up. (you know how it is, maintenance often takes second fiddle to production)

I wouldn’t worry too much about the motor cover. It just hides the top of the motor. the bottom is open so it doesn’t help the dust collector much.

The band saw; give it good once over. Check your blade guides and bearings, replace as necessary. check your wheel bearings and tires. make a new guard if it’s missing (I cant see) check your blade tensioner system, (it’s probably fine,) Then find a blade for it. Hopefully the new miter square for the table saw will work on it also.

-- nice recovery, They should pay extra for that mistake, Eric E.

Eric, Thanks for the nice comments. I never heard it run, it was in a barn and there was no way to check it out electrically.

In fact the motor starter swith device was not orginal – all that was there was an enclosure with a 60amp Square D breaker?

Not the ideal set up for a 3HP single Phase 230 volt.

With that in mind I am looking for a Single Phase 3HP Magnetic Motor Starter with on/off switch. What I found is this one (see photos) I think it is what i need, It may not be a heavy duty type, but then I will not be using the saw all that much. So it will not be switching on and off like in a cabinet shop.

If anyone has any other switches that they have used to replace the original one on a single phase 3HP please feel free to share that information. Thanks.

Meanwhile I am in the tear-down clean up stages. Happy New Year! RichmanNot

OKAY I have FOUND ANOTHER SWITCH… By chance does anyone have this switch on their PM66 3HP Single Phase saw?

It says it will work for the 3HP Single Phase? Does anyone know if it is a magnetic or manual switch? A magnetic type prevents the saw from starting back up if there is a power outage or interruption cycle. Thus it is more “safe”.

Description:
This on/off switch is an authentic OEM replacement part sourced directly from the manufacturer. It is compatible with multiple models of Powermatic saws. This switch contains the on/off function, overload, and mag starter in it for safety purposes. It is sold individually, and it requires a screwdriver.

I found this switch listed at this website: http://www.ereplacementparts.com/ono...-p-544687.html

It sells for $137.97. Perhaps this is is the switch I should get? COMMENTS PLEASE.

Thanks!

I am not familiar with that switch. I can’t answer whether it is magnetic or not. The one I work with doesn’t have one, but it has never been a problem. if you are on a budget (http://www.grizzly.com/products/Magnetic-Switch-Single-Phase-220V-Only-3HP-21-25A/T24101?utm_campaign=zPage&utm_source=grizzly.com) is magnetic and will work for about 45$ less.

Eric, I have had some great help from a member who knows his stuff about motor controllers and power saws. What I learned from him is that these switches are what are classified as IEC rated The best switches are NEMA rated. He has replaced many of the IEC types which nearly caused fires. The contacts in them are very inadequate for the long term and eventually cause issues even melting wires.

Therefore, I am going to go with a NEMA type of device and shy away from the lesser quality ones even though they take up less area and look nice.

I would agree with you about the NEMA rating. It has to do with dust control. Dust in the switch can cause many problems. We have 2 table saws in the shop. A Powermatic and a Delta, one tilts right the other tilts left. The Powermatic has the old style switch on it which almost never needs to be cleaned out. The Delta is newer with a magnetic switch and under similar use needs to be cleaned out every month or so.

Neither have a NEMA rating. Both are old enough that the rating didn’t exist when they were made. However If you are using it as a hobbyist I doubt that you will generate enough dust for it to matter. Even the ones with a NEMA rating can fill up with dust (I’ve seen it on a sander.) and they are a pain in the but to clean out.

I am sure that which ever one you choose will give a lifetime of pleasant woodworking fun, and that is the important part.

I consider this a great score!

I love rebuilding things, becoming “one” with the tool after finishing it (recently rebuilt a 1964 PM bandsaw and posted a blog ).

eReplacement has always provided top service when I needed the part and they were the only readily available source.
There prices are dear however, have a look at the PM website, they list parts for many things going way back and are cheaper in most cases.

Have your say...
