When you set your blades make sure to set them proud of the out feed table and the planer top opening.

I was curious about this statement as it goes against the conventional wisdom of setting the blades level with the out feed table. So I decided to break out the dial indicator and do a little measuring :) What I noticed is that when the cutter head lock is in place, the blades are just slightly in front of TDC. I leveled the jointer blades like stated in the manual and double checked with the indicator. Sure enough, when locked and leveled in that fashion, the blades are dead level with the out feed table, but about 0.002” proud at TDC. I didn’t bother checking the planer blades and simply verified with the indicator that they were both exactly the same height (to within 0.0005”) after leveling.

I imagine that this would work well for new (or freshly sharpened) blades as the cutting edge will wear slightly after initial use. 0.002” of wear? I dunno.. I’ll check on them with the indicator every now and then after some use to see what they do. Just for grins, I also set them dead level at TDC to see if there was any difference in performance. None that I could detect, and the slightly lower blades produced just as straight an edge as the blades set a few thousandths higher. They also moved the leveling block forward about 1/8”, which is about a half of what the higher blades did at 1/4”.

And no, I don’t have the tool kit. For the leveling blocks, I’m using some oak blocks that I fabricated up myself and made sure were perfectly flat. I have to admit, this is about the easiest machine to set blades on that I have ever owned and so far has been a joy to use.

Cheers,
Brad
