Thanks Bas, really appreciate this. I'm trying to get up the courage to set up my new/old grizzly jointer for the first time..... :BangHead: I think now I'm gonna have to put if off a few more weeks.... :swoon:
Don't let Bas fool you...he's sticking with the argument he used to justify that new J/P! :gar-La; :gar-La;
Setting straight blade jointer knives is not rocket science. I don't like doing it but it's something that needs to be done every now and then.
I use the stick method now.

I have used a dial indicator but find the stick to be close enough to work very well. I always bump the outfeed down slightly before starting then tap it back up to set final table reference after completion. ie, once all knives are adjusted, edge joint a stick.
Lay the jointed edge down on you flat jointer table and look at the end of the stick - the last part to pass over the cutterhead. If there is a raised area then raise the outfeed table. Repeat until the gap is minimal.
Some would say make the knives dead even with the top plane of the outfeed table but this will give you fits trying to joint long, heavy stock. Set the blade height just a smidge above the outfeed. If the stock appears to be hanging as you feed it across the blades then the outfeed table is too high and should be adjusted down a little. Once set it shouldn't need to be moved until you replace the knives again.
Now, if you're in the camp that argues over the need to have jointer table top surfaces flat to within .ooo1 inches then you can buy a gauge/jig to help you set the knives.
I like your thinking on the big jointer. Really I wish I had a 12 inch jointer, mine is 8. I have a 15 inch planer and it suits my needs just fine. The 12 inch jointer has long, wide tables that help support LONG stock...very nice.
All this is not meant to advocate flat blades. I wish I had a Byrd style head in my jointer and one day I just might. They are well worth the cash... if you have the cash. Not because they are easier to set blades but because of superior performance and reduced tearout.
