Hi, I recently changed blades on my old Boice-Crane 6” jointer. While I borrowed a jointer pal device from a friend and followed the instructions, I’m getting snipe about 1.5-2” at the end of the board. Thus it seems my knives are set a tad too high relative to the outfeed table.

Should I look to lower the knife height or raise the outfeed table? I tried making a DIY jointer pal using magnets glued to a p;iece of wood but am skeptical it is accurate/flat enough (I did sand it with a sheet of sandpaper on a cast iron flat table saw top).

As far as raising/lowering the outfeed table, I’m not sure how to do that. There is a knob very similar to the infeed table knob (which works very smoothly), but this knob seemingly just loosens/tightens a bolt and doesn’t actually move the outfeed table. Is the idea to loosen this knob and manipulate outfeed table height with dead blows from a mallet or something?

There’s a reason why outfeed tables are adjustable :-D

If your outfeed table isn’t adjusting with the knob, I’d be looking for gib screws on the outfeed side. They may be tightened down too much to allow movement (though I don’t see any in the photo).

No… the adjustment knob for the outfeed table works exactly the same as it does for the infeed table. Here are what they look like with the tables removed:

If yours isn’t moving the table, then something is wrong and you need to get under there and look to see if you can figure out why.

Cheers,
Brad

What Dustin said. Check for allen head bolts on the rear of the outfeed table.

What brad said about getting a dial indicator to set knifes.

My preference is a non magnetic so I can easily slide it across the table.

Yes, and that foot is broad enough to turn the head back and forth to see top dead center. The blade just glides across it. I have the same gauge and it’s a perfect example of a situation where a dial indicator beats digital hands-down.

Thank you all. The outfeed table now moves after I got some WD-40 in there. Turns out it is in the max height position and the blades are bottomed out…because the new blades (6” x 5/8×1/8) I ordered are a wee bit too tall. Guess I’ll take them to the grinder and see if I can shorten them up a tad.

That is the correct size knives, so you may want to investigate a bit further. The Freud C350 set fits perfect without any modifications necessary, and IIRC, there was still plenty of travel up/down on the outfeed table.

Brad

To investigate further implies I should figure out how to get the outfeed table removed. Should I be able to keep turning that knob counterclockwise lowering until the table just comes off? It lowers quite a bit and then stops. Not obvious how to remove the knob.

The table is held in place by one bolt, as I showed in your thread over at the OWWM site (and posted again here below). Remove it and the table will come right off. Give the ways a good cleaning and then wax or otherwise lubricate them so they slide easily. The table should be able to raise well above and below the cutterhead.

Cheers,
Brad

Ah, the bolt was on the bottom. Oops!

I figured it out. The spacers on the knob were on the wrong side. Thanks! This is a nice little jointer I scored for $50 a couple years ago.

They are nice little jointers and built rock solid. I got mine as a package deal along with a Delta 14” band saw for $170 – so figure $85 if you split the cost in half. Although mine also came with the original flare leg stand, motor and wiring. They do clean up nice:

Just for grins, here is what one looks like exploded :)

So now my outfeed table goes up and down easily, but it won’t stay set in a position. It gradually lowers with use. Hmm…

I didn’t look but I’m willing to bet it should have gib locks
