Folks -
I had some "tinker time" available today, and was finally able to finish a
project! Several months ago, I ended up with an old craftsman 6 1/8"
jointer on a rickety homebuilt stand with an underpowered ~1/3 or maybe 1/2
horse motor. The thing would stall out edge jointing pine, for goshsakes...
Anyway, I had build a sturdier roll about stand a few months ago and had a
HUGE old General Electric R.I. 1HP motor laying around. I installed the
motor and rewired the connections to change the rotation and switch it to
220v operation... I finished up with all of that today, also having
installed new jointer blades and truing up the outfeed table so everything
was level and square.
I fired it up and the thing just puuuuurrrrrrrrs.... I let it run for about
15 minutes after a couple of "touch and goes" just in case it was going to
throw a knife... runs like a top!
I used a dial indicator to set the knives and all that, but was wondering if
there was a better way to do it. Finding TDC was a bit dodgy in putting the
point of the knife blade square with the tip of the dial indicator. I
*think* I have all the knife blades at the same height, but am getting a
small amount of scalloping in my jointed edge. Any ideas?

John,
Glad to hear you have tinker time finally. I'll e-mail soon, busy here.
I use the Magna-set for setting my jointer blades, quick and accurate.
Before I got that I used two magnets set on the outfeed table. Rotate the
blade til it's at it's high point then tighten. The magnets hold the knife
while tightening. Works for me. My 2 cents.

That's doubtful unless you have your knives ground all at
once "in the head". Not crapping on your technique. It's
just a fact of all things with non-fixed multiple cutters.

Slow your feed rate.

I lay a straight edge on the out feed table against the fence overhanging
the cutter head.. I rock the blade back and forth until the straight edge
does not lift the straight edge but I can feel the knife hit it. I then
repeat at the other side of the knife and then recheck the fence side. I can
change a set pretty fast like this. Trust your sense of feel.
