Topic tags/keywords: jointer table adjustment

So here’s the gig … bought a jointer off CL, derusted, painted,lubed, and put back together. Now heres the part im a little confused on. The tables are out of whack a little bit .. not a ton but theres a noticable bow from out feed to infeed with the cutter head being the high point. I check with a level (i know its not a real straight edge but its what i gots)

The jointer is a rockwell 37-220 6” with 44” of table. There are 4 allen head set screws at the rear of both the infeed and outfeed table. 3 of the 4 appear to push on the dovetail slide. When i tighten them up snug the tables dont want to raise or lower.

I watch the wood whisperers jointer set up vid, and while it was super informative he was asjusting an 8” powermatic which has completely different adjustments. Am i going to have to shim the dovetails or am i missing something?

Whatcha folks think?

If you have access to Fine Woodworking, I used http://www.finewoodworking.com/FWNPDF/011142038.pdf to tune up my jointer. It works perfect albeit the dull blades.

You have to tighten the screws differently. The one closest is the tightest while the farthest one is the most loose.

what do you mean as far as “bow”?.... is your table smiling at you or are your tables (in-feed & out-feed) co-planer? more info on where exactly its bowing would be nice.

If your cutter head is your high point, there is your first problem. Your cutter head, at its apex, should be at the same hight as your out-feed table.

Is there any way for you to take a picture of the whole jointer?
On the outfeed table, what’s the circle for? It looks like where the guard goes.

sean .. its frowning at me basically. Seems like infeed and outfeed tables have sagged at their respective ends. Ive got the outfeed table a scosh higher than the blades i just didnt want to nick a knife with the level. See pic below.

Tyrone – its the back of the jointer i honestly have no good idea what that circle in the rear is for. Ive got a parts breakdown, manual, advertisements .. all the goodies … decorative i presume. Or maybe there was originally a rod to hold the outfeed table when angled?

I now understand what your saying. If you can loosen that allens. you might have to pull on the circle knob in the rear to release your adjustment. If anything sticks hit it with wd-40, or my personally favorite PB Blaster(its like wd-40 on steroids). I’m not sure if that knob is a release on your rockwell, but thats how my 6 inch powermatic tables come off/adjust. I’d try cleaning it real good after that, reassemble and see what you have.

You may be forced to shim…. thats if your your castings are flat, and the bow is product of the way the tables are sitting on the machine base, causing a splay.

If there are bows in the castings themselves, you may have to have a machine shop mill them flat.

When i put a smaller straightedge on the outfeed table only its dead on flat and the same for the infeed table, dead flat. But when i lay a longer straightedge across both surfaces i get the frown. I dont like frowns. Ive cleaned and lubed this hog up with everything i got. Ill give it a tug and see what happens (that was bad). All the allens move nice n free.

Hey Chris, The 3 screws you are referring to are the gib screws. The gib is the small piece of metal that slipped into the dovetail of the ways. The ways are the dovetailed parts which the infeed and outfeed tables ride on. The gib screws will not level the tables. They are there to keep the tables aligned and to eliminate slack between the table ways and the ways on the bed of the planer.They are tightened only enough to allow the tables to be moved up and down in a smooth manner. But with no side to side movement.

The wear is normally on the infeed table because the outfeed table is set to the height of the cutterhead and left there. The infeed table is the one moved to set depth of cut. So it sees the greatest wear.

yeah,
you might have to shim. I’d try to get away with only shimming your out-feed table, mainly because it is typically never adjusted after your machine is dialed in.

maybe someone else might come up with a better solution, but thats the best I can personally think of at the moment.

good luck

Thanks for the explanation kutter, its not only my first refurb itll be my first jointer as well, hopefully i can get it into workable condition. I know that currently some are tight some are loose so ill look into whats really going on there. Im also yet to adjust and set the knives.

I just reread your posts and I would suggest removing the blades until you have everything else setup and aligned. The blades would be the last thing to install. Less chance of an accident. Both to the blades and to your knuckles.

That way you can remove the cutterhead guard and get it out of your way.

I have read what the other LJ’s are saying and I think they are dead on. I believe you will not need to do anything to the outfeed table. I know it seems to be sagging now but if you raise the back end of the infeed table far enough I think it will line up with the outfeed table. If not then you might need to adjust or shim it also. They are absolutely correct when they say the knives should be the exact same level as the outfeed table. If not it will not cut the board straight. the infeed is most likely the problem. Like they said it is adjusted all the time and it gets the wear. Good luck on this thing. It can be done.
