I have a powermatic 66. When you tilt the blade and straighten it up it moves about 1/16 of an inch to the right. The set screw on top of the shaft is as tight as it can be. What can I do?

    I cannot see another set screw. The plans that I have do not show another set screw. These are the plans that came with saw when I bought it.

I am not interested in payment for this suggestion so you can refuse to pay.

I would FIRST check the endshake of the arbor shaft. It is possible the shaft shifts sideways if the bearings are not shimmed correctely. Using the saw at a tilt sideloads the bearings and the arbor may move sideways and then return when tilted back to normal.

Grab ahold of the arbor and see if it will move sideways. If it does, you need to put shims in the bearings to take out the slop.

Hello. Remove that set screw all together. I believe you will find that there is a 2nd set screw as well. If either set screw is flattened on the end replace it. Set screws are available at most hardware stores. J.

How do I adjust the worm gear on my table saw?


I believe that that model of Powermatic has a lock for the blade angle that also extends and retracts the casters for moving the saw. You may have unlock or change the handle position to allow for blade angle adjustment. You can get a manual or information at the Powermatic website to show you how to change the settings on the saw. Hope that helps.

I have a powermatic 66 table saw. I removed the motor, to move the saw. when i reinstalled the motor, the blade has moved 5/16'' towards the fence.


Check to make sure the arbor set screw is not loose. The bearings may have shifted when you moved it. I recently rebuilt an old 66. Repositioning the bearings and tightening the set screw could be all it needs.

Blade out of alignment with miter grooves in casting top. how can I realign?


Do an online search for "table saw tune up" and sort through the articles to find one that gives detailed instructions on how to check for blade runout and how to test blade alignment with the table top. Here's one that covers the basics quickly and concisely, but there are many to choose from. Compare them with information from your powermtic user's guide.
It's a laborious process that will take a day or two and you need to loosen the bolts that fasten the saw trunnions/ mechanism to the cast top, and physically shift the alignment of the saw arbor relative to the mitre slots, then recheck it for alignment, etc. until you get it right. Sometimes you can loosen several corners and leave one kind of tight to shift the saw in the direction you want to move. Download the online manual from powermatic here by choosing your model and you'll have onhand a detailed parts diagram to guide you. If you're not up to a gruelling process, and don't have the appropriate tools, I recommend you re-check your blade to ensure it's not at fault and see if you can't live with it as is.
Otherwise, good luck and be patient. It's worth it to have it right, but wood is only wood, and at some point you have to just do the woodworking.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

I am thinking that you have mistakenly crossed 2 or more wires, hopefully you wrote yourself a wiring diagram or there is one inside the motor cover. I don't know if I can find a wiring schematic for this tool. If you still have the owners manual look in there for initial setup and see if they provided one. If you need more help let me know and I will do what I can.

My Powermatic 66 tablesaw has a 3 phase 230 Vac motor on it but I cannot tell if it is a 3 hp or 5 hp. All the tags are gone from the motor. Is there any way to tell from the serial number? 8666-1008.


There will be a tag on the motor that will give the specs. Sometimes they are hard to see from the underside and its not easy to remove the top see them. Try lowering the motor (with blade removed) all the way and use a digital camera to reach up into the cabinet and photoqraph the top of the motor. I had to take several since your shooting blind to get a picture of mine.

How to adjust my til tof my 10


When you are facing the saw as if you would be operating, there are two adjustment wheel on the front and right hand sides of the saw cabinet. The front wheel adjusts the blade height, the wheel on the right side of the cabinet adjusts tilt. Each of these wheels are equipped with a locking nut, a smaller wheel in the center. this must be loosened before any adjustments can be made and should be tightened before operation. If there is significant resistance while trying to adjust either of these it may be a result of misaligned gear or excessive buildup of dust and shavings on the gearing.

Your saw motor is equipped with a two speed internal start switch. Over time saw dust will get into the contacts and cause the points to burn. You can pull the end off of the motor and take some 400 grit sandpaper to the contacts to clean them( there are two sets of contacts one works in the out position the other in the in position) it will be the set in the in position that is the problem. Gentle clean them, reassemble the motor end cap and it will work fine. I have to do this about once a year to my saws. I use my saws about 25 hours a week. I have been doing this to one of my Powermatic saws for 31 yrs. now.
