Setting Jointer knives, tolerances?

[Alan Greene]

I am replacing, and setting my jointer knives for the first time. I am also setting the out feed table to the first knife and am going to set the rest of the knives in relation to this first knife. My question is are the following readings good.
Going from the outer edge towards the fence at each bolt the numbers are:

-.0025, -.003, -.0025, -.0025, -.0035

Also,how tight should the bolts be holding in the knives. They are not quite to the point where I feel the wrench my slip, if that makes sense.

Thanks in advance for the help:D

I have 4 hours in getting this knife set, hopefully with the lessons I learned from this one the rest will be a little quicker. You can read about it till your blue in the face, doing it is really the only way to learn, and it's more fun:eek:

Sounds like that One Thousandth of an inch from one end to the other What's that a 12" jointer?

I'd leave it alone.

Torque? Check the Grade of the bolds and consult any spec sheet such as these:

Check out this thread (http://www.sawmillcreek.org/showthread.php?t=20579&highlight=jointer). Scroll down to Per Swenson's post. It should help get you consistency throughout the knives and align it to the out feed table at the same time.

Randy, I had read Pers thread a couple of times. Call me "enter desired description" but I wanted to be able to do this without the benefit of the jigs one time so that I fully understand what I am doing when I do use them. I am going to make the glass jig for next time.

Cliff it is an 8" jointer. I have tightened the bolts so they feel the same as the ones I haven't touched using the elbow torquemeter.
