« Part 8: Father's Day Tool Gloat..... Part 9 of 3 Girls & A Woodworker series Part 10: Which should i buy »

Hello everyone, i’m really hoping someone can shed some light on this problem for me. I have an older craftsman Jointer/Planer that is in great working condition, however it has one major problem. Even though the infeed and outfeed tables are parallel when i push a board through it raises up off the outfeed table. Hopefully the pictures below will help…...

To me the table look very parallel weather the depth is set to 1/8” or zero. Now time to put a board through…..

So as you can see it begins to raise up more and more the further i push it through the jointer. I have to keep that back end held down really well or it’ll teeder and no long cut. I have no clue what i’m doing wrong here, i’m really hoping that it’s just a user error. The tables are flat and parallel in my opinion.

I really look forward to any responces you all might have,
Thank you

John G.

Does the outfield table line up with the cutter head? It looks in the picture that the cutter might be a little low

it’s actually dead on. I thought it might be high since it teeders and it might be doing it on that. when i put my framing square on and spin the head (manually) it’s just at the framing square but not moving it…..

this is an issue with some of the craftsman jointers. If i remeber correctly you can shim the mounts to level it up.

ahhh now i see why u think that, in that one picture i have the cutter head turned between blades so it looks low, if i had stood a blade verticle it might have been a better picture…..

Gary K. wrote a blog about many of the questions you’re asking. He had some simple ways to set the tables.

Ahh ok.. just wanted to make sure. If the head was low compared to the outfeed table, it might do what you described

@Don W. Yes i can adjust the infeed table at both ends but then it’s not parallel. Should they not be parallel??

@devann: i’ll try looking or that….

are you putting pressure on the lumber on the infeed table side? you shouldn’t. (sorry if this is obvious but from your post I cannot tell how you operate the jointer so there might be user error here as far as I can tell).

you should feed the lumber until it passes the cutter head enough that you can then apply LIGHT pressure against the outfeed table. the infeed table is below the cutterhead so any pressure put on that side will tend to lift the lumber off of the outfeed side which is what you don’t want happening.

as long as the outfeed and the cutterhead are leveled you shouldn’t have this problem as long as you operate the jointer properly.

i usually put alot of pressure on the infeed table. It’s the only way i can get it to keep cutting, when i put pressure on the outfeed it seems to life it off the blades. I wonder if my blades are to low…..

but it seems to me that if the tables are parallel, the cutterhead is even with the outfeed, then u can put the same pressure on both sides and it won’t make a difference.

Ofcourse that is unless you have a bowed board then it would be curving up away from the outfeed…. hmmmmmm wonder if that my problem wonder if i’m jointing a curved face so it’ll never sit flat. I may have to try that pressure on the outfeed table.

No need for apologies Purplev i have never used it successfully so i’m guessing i’ve been wrong this whole time….

fair enough – I would strongly recommend getting a book, or at least checking some online videos on jointer use…

consider this – you are trying to take a twisted board and flatten it. on the infeed side of the jointer you will always have an unflat/twisted board that is subjected to move around in relation to the cutterhead (tilt etc). putting pressure on that side is pretty much guaranteeing that you’ll have an unflat board coming off the jointer.

the only part that is true and flat is what passes the cutterhead, and that is on the outfeed table side. keeping the pressure there maintains alignment between the now-flat board and the cutterhead which allows the cutterhead to cut the rest of the not-flat board in relation to the flat part of the board (on the outfeed side).

more than that it’s about safety as well – putting pressure before the cutterhead, and having the board snap/break/burst/ pull under your hands puts your hands at risk from being pulled into the cutterhead (remember you are pushing toward the cutterhead) on the other hand – pushing beyond the cutterhead leaves your hands clear of the danger zone.

one more thing – if you need to put a lot of pressure on the board in order to joint it – something is WRONG in your setup!!!! STOP ! it’s probably unsafe.

the pressure on the board when using a jointer is merely to keep it from lifting up, but is really a rather light pressure against the outfeed table (once the board passes the cutterhead that is).

I would recommend getting familiar with jointer operation and setup, you’ll find that the jointer will be much easier to use, and will provide much better results, without the added risk.

good luck

John if I am reading this correctly the out feed table should be even with the zenith of the cutter head and the infeed table should be lower than the out feed by the depth of cut.

John, I suspect that they are NOT parallel, no matter what the pictures above are saying. Just for grins, do you have one of those Wixie angle boxes for measuring the tilt of your TS blade? Or can you borrow one? Put it on one table, zero it, then put it on the other table. Also measure it at different places on both tables. Another thing you can do that is a little more costly is to use a good dial indicator to check between the two tables. Sorry, but that’s the best I can do for advice.

I think purplelev has nailed the problem. I would only add that you should joint the “frowning” [concave] side of the board and not the “smiley” [convex] side or you will make it more convex with every pass. Dont ask how I learned this! It appears your jointer is set up properly.
