I just purchased a new Grizzly G0715P and after reading various reviews I was inspired to use a veritas level, feeler gauges, created a couple jigs for my dial indicator and off I went. Following are my measurements:
Table top flatness—.004 variance with a dip around the blade opening
runout on arbor itself—less than .001
Miter slot to blade alignment— .0025, adjust to less than .001
Miter slot to fence alignment— adjusted to .006, there is some wavyness on the plastic fence face that is the culprit.
fence deflection—.006, used what I thought was a realistic amount of pressure
measured from the center the blade it moved out .006 from 2.5” above the table (had stabilizer on blade and any higher and it interferes with the cut) to as low as I could measure as it was lowered and raised.
Keep in mind I am measuring off of my forest woodworker blade and there is room for human error, but do you guys think these variations are acceptable? If you think I should be concerned about any of these measurements please share your opinion. Thanks you.

Personally, I’d be real happy with stats like that. My only concern would be the fence,
and a minor concern at that. Which fence did you get with it ?

It comes with Grizzly’s Beisimers knock off. It has a thick white plastic face that is attached to the fence that appears to be the problem.

Lots2Learn,
Have you contacted Grizzly about the fence ?
If the fence is problematic when cutting I’m sure they’d appreciate
the opportunity to help you correct that.
I can’t say that I’ve heard glowing reviews about the stock Grizzly
fence, but I can’t say I’ve heard much bad about it. They do offer
several upgrades over the stock fence…
Looking at the 2011 catalog I have to say that’s a lot of saw for the
money, and a good looking one at that. Nice buy.

None of those numbers would concern me. Wood can move a lot more than that on any given day. The day a deviation of 0.006” on my saw is the main cause of a project not coming out as planned, I’ll be a happy camper!

Most of the lateral pressure on the fence occurs just before the blade, so your real world deflection should be even lower than what you measured. It might be possible to shim the faces flat, or flatten them on a jointer if you think that’s a concern. Make some cuts, measure them, and let them be your indicator of precision…that’s really what matters.

Fences that clamp at both ends aren’t without other potential issues, as they tend to be prone to skewing out of parallel if you’re not careful when you set them. Deflection from use on a good t-square fence that locks on the front rail only should be miniscule.
