Hi Everyone,
I have a fairly new powermatic 54HH that i have barely used, but it is now out of warranty. When i finally tried using it, i noticed that when i go to run a board over the blades to take off a 16th or less of an inch, the board bangs into the outfeed table. Powermatic rep says i need to readjust the outfeed table. There are no specific instructions for that in the manual. There are four or five gibs in the back of the outfeed table and i have no clue how to adjust them. Has anyone ever had to do this? Or can someone stear me to a location on the web that shows how?

Thanks in advance,

Bryan

There should be a single lever or knob that adjusts the height of the outfield table. Just make sure your outfeed table is at the same height as your cutter inserts when they are at TDC (top dead center).

The manual will definitely have a section on adjusting the outfeed table. Check again.

here the manual: http://content.powermatic.com/assets/manuals/1791279DXK_man_EN.pdf

This is an easy adjustment, will take you about 2 minutes.

1) Loosen the ‘gib screw lock’ (fig. 22, p. 17)

2) Turn the ‘outfield table hand handwheel’ until the outfield table is level with the cutters at TDC (fig. 21, p16). To check this, take a heavy straight edge (the base from a combination square works well) and extend it from the outfield table over the cutters and carefully spin the cutter head by hand while adjusting the outfield table height (unplugged first!). When you find the point where the cutter just barely kisses the base of the combo square, you are level with the cutters. you should see the square lift/move ever so slightly as the cutter passes under it.

3) Tighten the gib screw lock.

(EDIT: Gib adjustment is only if your tables are not co-planer with each other or the cutters- no need to mess with them)

(DOUBLE EDIT: If you find the outfield table is properly adjusted, the problem may be technique. If you are not experienced using a jointer, you might not know that you should be putting all of your pressure on the outfield table as you feed the board through, not the infeed table.)

Thanks guys (except nothanks to Robert…...must be awesome to never have had a simple thing stump you.)

My main concern when i looked at the manual was that it didn’t spell out if i had spiral cutters instead of the knives. Also its a bit confusing that the wood goes over the cutters fine when the infeed table height is 0 but then gets hung up on the outfeed table when i adjust it up for a cut. And my straight edge shows no gaps when laid on any spot on the table. But will look at it all again and make the adjustment and see how it cuts then.

I am stumped thats for sure!
Here are the facts behind my comment:-
1. The machine has a 5/2 year warranty,
2. You signed up signed up 01-26-2016 01:32 and
3. In that time you have made nothing?
4. And now specifically after reading your reply above regarding being confused,

I say again,

Sell it! no doubt a great tool in the wrong hands.

atlas227,

I agree that if the outfeed table stops the jointing on range of boards including those that are relatively flat with a relatively straight edge, the outfeed table may be too high relative to the cutters. But it is fairly easy to adjust the outfeed table down too much, making it lower than the cutters. If this over-adjustment occurs, snipe is often found on the trailing edge of the board.

However, even with properly aligned cutters relative to the outfeed table, a badly behaving board can be stopped by the outfeed table. For example a bowed edge that only offers two points of contact with the infeed table can drop as leading edge is cut away, causing the leading end to contact and be stopped by the outfeed table. When the stock is removed from the jointer and the cut restarted, it more often than not passes onto the outfeed table without getting hung up.

Here is a jointer troubleshooting article that addresses technique and setup problems…

I’ve had to adjust a few jointers but the only kind of adjustments i usually do on the outfeed side are raising and lowering. If I do any adjustments for coplaner, it’s to the infeed table to make it match the outfeed.

For me, it’s easier to set the outfeed at whatever plane it’s on to the knives. Once that’s done, then it’s setting the infeed to match the outfeed.

Have your say...
