Blade Runout

[WestofLongBeach]

I am ripping 2x4 maple, a heavy task for my 3100, so needed a different blade, according to many who helped me with the issue 'round here.

I got a Freud Diablo 24-tooth ripping blade. It's handling the task much better than the native one. The blade is a bit wide, so the kerf is far from exquisitely small, but it was only $30 @ HD.

Now.

I noticed the first time I started it, that it has a bit of runout: about 1/32".

I couldn't find my **#)_@ ##!! feelers, which I used only two months ago, so couldn't be more accurate, but it is definitely between 1/32" and 1/16".

So. Do I need to be concerned? There was no runout with the original blade. Should I take it back to HD?

Thanks.

Don.

Don,
Loosen the arbor nut and rotate the blade about a quarter turn If this doesnt work, clean the blade and washer surfaces and retighted. If this doesnt work, exchange the blade.

Don't overtighten the Arbor nut. This can distort the blade. A little distortion at the center becomes a larger amount going out. Snug and about a 1/4 turn more is all it takes.

Wayne Hill and Lchien,

Thanks for replying. I'm sorry that I misled you. After writing (I no, I no, should have done it BEFORE I posted) I changed the blade.

Turns out that there's the same amount of runout with the original blade. When I first got the saw, it wasn't obvious to my new-to-table-saws eyes, I suppose. So. Is 1/32" acceptable (don't see how it could be) or what should I do?

Thanks.

did you clean the blade washers and blade spacers before reinstalling the blade, also rotating the blade, as Wayne suggested?
A small piece of grit or chip of wood (like 1/128") on the washer can make a much larger deviation (about 1/32) at the end of the blade.

Thanks, to both of you.

Since the runout seems to exist in both blades, I think it may be as was said, a small bit of something in the arbor somewhere.

I'll be out there later this week, and try to clean everything up. And, try rotating the blade to see how it sits. I'll report later. Hm. Possibly the runout wasn't there on first assembly, after all.

Does anybody know where I put my feeler gauges?
