Rigid R4511 blade arbor wobble

This video shows the wobble issue at the blade stemming from an arbor which is out by a thou. on my new table saw. At the outer edge of the blade, that thou. translates to six thousandths. That low tolerance leaves a terribly rough cut, even with a brand new forrest woodworker II and Lee Valley blade stiffeners.

ill admit i have the same OCD in wanting to weed out every bit of intolerance on all my machines... but on my wood working machines, i do it for the challenge rather than thinking that if my blade wobbles a few mill that id ever even notice it in the cut... which a few mill, you wont

A new belt, not broken in, would throw off more vibration/imperfection than the tolerance fault on that arbor.

Seriously, cut some wood. Enjoy. If you want something better, you probably will have to shell out a few more thousand.

@NickC84 i read somewhere that phenolic is a very messy material to cut up, even if there's a vacuum system in place. thanks for the reply

@odmcarp I made my inserts out of 1/2 inch MDF and shimmed it a little. But you can use phenolic or any other kind of wood really. I just used what was around.

@NickC84 i agree .001" run out on any saw is unbelievable & .006 on a blade is even more impressive. i just got this saw at home depot today, and paid $299 plus tax. can't wait to start cutting. i had a sears craftsman table saw for over 20 years. so the difference should be like night and day. question, i want to install a zero clearance insert, what's the best material to use & how does it stay in place? i can do this on my own, but would like some ideas on what others are doing. thanks

You expect your blade to have less than .006" run out? I think you're in the wrong hobby. You arbor video shows that your arbor is off by .001" that is well within tolerance of a table saw arbor. I understand that you want the highest degree of accuracy but you have to understand nothing in the world is perfect. Cut some wood and enjoy your saw. It's a great machine.
