We have a 1981 Rockwell 8" Jointer that has started to cut tapers. I have figured out the cause, it is the table adjusting screw and nut. To fix it, it requires a part that is no longer made by DeWalt. I talked to my superintendent about it and told him that we are trying to have one machined, but are unsure if it will work (it probably will work and will probably be better than the original). I told him that it was just a band-aid because I am not sure of the condition of the threads on the other table. I was told that if the machined part does not work, we will replace it now, otherwise we will wait until summer.
My question is, does anyone know where I could find the part to fix it or purchase a new one?
When I purchase a new one, does anyone have a suggestion? Our current jointer is 3 phase and I would like to replace it with the same size and phase. I am looking at a Powermatic PJ882H 8" with the helical head. Does anyone have any experience with this machine?

You might try posting on www.owwm.com. It is a wealth of information on old machines and repair. Lot of neat info on manufacturers and manuals. I guess a lot of us instructors are in the same boat with outdated and unrepairable equipment that we have managed to keep running over the years.

I too would try owwm. They have a great buy/sell forum called Bring out your dead. If you don't get the info you need within 48-72 hours then it isn't going to happen. The folks on that site are great.
I replace my powermatic jointer with a new one that has the Helical head. Its been great. It faces well and the edges perfect. There is some plastic crap that I removed because it wouldn't stand the test of kid time.
If you have other questions give me a call 541-318-9891, I'm here 7:00 to 3:30 PST

Well so far, I have not heard anything back from OWWM about my account so I can post a question. However, I got a call from my principal on Saturday. I was informed that he located a used jointer. He and the superintendent decided to purchase it sight unseen. I have to go pick it up today after school. I just hope that it is not a p.o.s. I am wondering if I have to do anything to it to get it operational.
All I know about it is that it is an 8", 3 phase Delta, and we are unsure of the year or the table length. I am hoping that I do not run into the same issue with not being able to purchase parts in a few years if and when it breaks down.

I had a Delta / Rockwell 8" jointer just like you have. I replaced it with the Powermatic 882HH with the same cutting head you want. I love the machine. It is easy to use and set up. I have had it for 2 years and have only needed to rotate the knifes once. It was simple... It is also about 1/2 a loud as the straight blades.
Let me know if you have any specific questions.

Where did you purchase the cutter head from? Ours is not all that noisy, but I would like to make it a little quieter though.

We installed a Byrd head into a Powermatic 180 planer and it was worth every dime. After running that head for a year, I tore the planer apart and completely rebuilt it. Milled the bed, replaced bearings, belts, and repainted to match the colors when it was built.
Now this 38 yearold planer out-performs any 18 inch planer on the market. (or so I have been told)
The other advantage is now it only takes 30 minutes to sharpen as opposed to 8 hours it took when the machine had the old stagger head.

Craig:
You might try swopping the infeed and outfeed table nuts. Once you have the outfeed table where it belongs, just lock it down. The outfeed nut should not be worn.

We had a new nut and shaft machined at the prison in town. I looked at it and it looks like it is perfect, works smooth, like it is brand new. Unfortunately, the jointer is now retired. My principal found a used one that is the same model, only a few years newer. I was told to go pick it up. When I got it back to the shop, I noticed that it was not a 3 phase like our old one, so I had to swap jointers. I took the newer one and put it on the old base with the old motor. Aside from the name plate, you could not tell that it is a different machine.

This is my first post. I have a very similar jointer (an old 8" Rockwell Delta not sure of the year or even how to tell) that is also having the same problem (cutting tapers along the face of the stock) but I don't have a clue on what to do to figure out the cause. I looked at my jointer and I'm not sure what part you are reffering to. Can someone please help me? My solution to the problem to this point has been to just reverse the board each pass to counter the taper. I realize this is an amatuer solution but I don't know what to do besides purchase a new jointer which at this point is NOT an option...

Welcome
Typically the cause is that the outfeed table is either too high or too low. There should be a stamped piece of steel that attaches to the head and holds it at the correct position for setting the knives. This is also helpful for getting the table correctly adjusted. (If you want I can take a picture of ours and send it to you. I inquired about a new one, and was told by Delta that it would be about $150.00 I passed because I was able to locate the old one.)
Under the tables, there are wheels that you would turn to raise or lower the table. Make sure that you unlock the outfeed table before trying to adjust it and that you securely lock it when you are finished.
