Stopped at Harbor Freight on the way home this evening and used my 25% Super Coupon, good only until Sunday. The dial indicator did not clamp tightly to the mag base arm, but I fashioned a couple washers from some gasket material. That allowed the dial indicator to be fastened to the arm without moving.
I measured the arbor flange run out about 3/32" to 1/8" from the outside edge of the flange. Super flat, less than .0002. Probably closer to .00012 ~ .00015. Hard to say with certainty as the dial indicator is marked only to .001.
The blade is a different story. I did the measurements just below the bottom of the gullets with the blade raised to its highest position. I picked a random spot, marked it and zeroed the dial. I was getting variations from + .003 to - .005~6. In my opinion that is way too much for an expensive blade. Still not as much variation as I am getting in the throat plate. Can this blade flex upon start up ? I bought the blade earlier this year at the Tampa wood show and it has a thirty day return policy. So no sending it back. Can the blade be straightened ? Is it worth the money for shipping both ways and the charge to fix it ? I guess I will call Ridge Carbide and see what they say.
I need to do the measurement on the teeth again. I was getting tired and sloppy, but the teeth edges are out also. Maybe due to the disk not being flat.
I also took a bit of tension off the drive belt, it was really tight. I will try loosening it a bit more, as I think it is still tight enough that it will not slip while cutting wood.
