I can't find the cross reference you seek, and am wondering if Penn State no longer makes or supports this planer. (Here's one archived review from 1996.) However, any reputable sharpening shop should be able to provide you with tool steel or carbide planer knives, or resharpen your existing knives. If the knives have specialized holes for mounting, etc, there may be a surcharge for drilling the steel to fit your planer, but I suspect with the economy the way it is most sharpening shops will be happy to undertake the task. If they balk, find someone who's qualified before you spend the money on new knives. What is important is the the thickness of the tool steel is comparable with your knives and the width is within the specs of adjustment for your planer. Usually normal tool steel will get sharper. whereas carbide is tougher to wear out.
If you can't find anyone local, I can wholeheartedly recommend Precision Sharpening in Albuquerque, N.M. They have quality grinders and do professional work.
If your knives are of the disposable type and your can't locate a substitute, try contacting Penn State Industries here.

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

Hello,
I am not familar with the Jet but have set up alot of planers.
-When you say cylinder do you mean "head" (a head is what holds the knives)?
-When you checked the head being parallel did it have the knives in it? If so it's most likely a knive problem.

-As far as the table being in a bind I don't know.

I would go to you tube and look up "planer set up" , I have viewed alot of there set up videos and they cover alot of the issues you are discussing. The wood whisper videos are a good place to start.

Hope this helps.

You mean you're getting speed bumps? Do you have the blade setting tools that came with the planer? You need them, it will be hard to do without them. It is a little C shaped jig that rides on the drum over the knife, you have your knife sharpened and set in the drum, snug, not tight,under the knife are adj screws, you run the knife setter around the drum and just scrap the top of the knife, do not pull the knife, just go over it barely scraping it, then snug it up, do not tighten anything yet, move on to the next screw, do the same thing, then the last screw, then go back to the first, still good? second, third, now, tighten them up, the setter doesn't pull the knife, just barely scrapes it, but it does hit it. Now do the other side. Both knives will be set the same, no more speed bumps, or uneven cuts. To move the knife back in, if you brought it out too far, use a block of wood to tap it down, make sure you put the elevation screw down first. Do not answer the fone while doing this. It is serious stuff, when those knives start flying. Hope this helps.

Surely you have some mounting screws for the Knives, don't you? You may have to loosen those and Re-set your Cutter Depth & Level. I use a "Step-Gauge" to do that with. In some Rare Cases you may have to shim to attain the desired results.
