Circle mill headblock/blade clearance?
« on: July 05, 2012, 04:30:40 PM »
I've looked through all the reference manuals that I have and can't seem to find an answer to my question. What is the recommended clearance between the edge of the headblock and blade? I'm ready to fabricate the beams that will tie the track frame to the husk. The only missing dimension is the blade/headblock clearance. I'm thinking it's something like 1/2" or so but I want to be sure before I cut and weld the beam. Thanks guys!

1/2" is mentioned in Stan Lunstrum's Circular sawbook.

Might have to do with how thin you want to go with your dog board, and how close the dogs will set to the knees.

   I like to be able to saw down to a 1" dog board, so 1/2" will likely allow you to do this without to much danger of the board falling off the knees. I have mine set to clear by about 3/8" while at speed.

I'm right in there with Alan. That is exactly how mine is set up.

I always keep an eye on the saw guide clearance to the blade. Make sure the guide won't allow the blade to run out enough to hit.

Thanks guys. I'll set up the frame to allow the clearance to be adjustable from 1/4" up to 3/4" so I can dial it in once the mill is up and running.
