Rockytime Posted April 5, 2019 Report Share Posted April 5, 2019 This is not exactly a problem for me but more of a curiosity. The saw cuts well but prior to starting the cut I can see my blade moving slightly in a left to right movement. Very slight but enough yo recognizw. I don't have a problem but then I don't do real fret work. Is this unusual for the Hawk? And how do I correct it if it is?

fredfret Posted April 5, 2019 Report Share Posted April 5, 2019 Mine does the same thing. About +/-3 thousandth goes away when the blade starts to cut. OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
Scrappile Posted April 5, 2019 Report Share Posted April 5, 2019 Same here on both my Seyco and Hegner.... I never worried about it... Keep scrolling. OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
OCtoolguy Posted April 5, 2019 Report Share Posted April 5, 2019 I'll bet the top and bottom blade clamps aren't in sync with each other. It only takes a fraction for this to happen. If you do any 3-D scrolling you'll know really quick. The blade has to be at a perfect 90º to the table. It requires moving the set screw on both blade clamps so the blade is perfectly vertical. If you have already done that, something else is amiss. Possibly a bent arm or worn bearings/bushings. Quote Link to comment Share on other sites More sharing options...

Very easy to check. Lay a machinist square next to the blade and move the arm up and down and watch the space between. Also take a block of wood and draw a straight line on it and place behind the blade and again move the arm up and down and watch the blade. These are the basic checks for all saws. If they are out move the table or move the set screws. Most likely the table got bumped. Most tables pivot on a single point so easy to move out of alignment.

Ray, I think you nailed it. The screws in the clamps could definitely be adjusted to make micro movements to reduce the movement. It is so minor I think I will not bother.

I like to have stuff "spot" on. Sort of like working on a clock. Quote Link to comment Share on other sites More sharing options...
Rockytime Posted April 7, 2019 Author Report Share Posted April 7, 2019 Spoiler I could do that. The top clamp would be unchanged and my four bottom clamps would have to be adjusted to be in sync with the top clamp. I think I'm not quite ready to do that.
