Well, I've been working with these chucks now for a few weeks, and I must say... I'm not impressed!
I can no longer get a straight up and down cut, it always comes out at an angle.
When I set the table angle to be 90 to the blade, what happens is the cut ALWAYS comes out at an angle. I've used 3 methods to confirm the 90: cut a notch into a piece of wood and flip it around to see if the cut fits from behind, a magnetic digital angle gauge, and a small carpenters square.
IMO there is way too much adjustment right/left in the chuck adjustment screws and I am unable to get the correct angle to cut a straight up and down cut.Consequently all my puzzle cuts are garbage as they can only be aligned from one side!
I have adjusted these heads for hours now and I've given up on them.
I put my old heads back on the saw, problem fixed but the noise is back LOL
I won't be buying another set!
