Milling table saw fence

Blade bodies can have a bunch of wiggle in them. If you want to check run out you need to get right up on the arbor flange.

Run Out of 0.011 is major excessive. You should be talking 0.002 or less. You either have a warped blade, bent arbor, or poorlly faced flange.

Some notes for your consideration:
1. Don’t touch the blade with anything other than the dial indicator when you are taking the measurements.

2. Find the high spot on the blade, and mark it with a felt tip pen.

3. Loosen the blade and rotate it 180 degrees from it’s original position, making sure the arbor doesn’t move.

4. Find the high spot on the blade again. If the high spot is where you marked the blade, then the variation is caused by the blade. If the change is nowhere near the original spot then the problem is in the arbor and/or flange.

Hi, woodbutcher,

I sell UHMW offcuts and I’ve worked with this stuff for years.

It’s perfectly safe to run your UHMW through a surface planer.

Just don’t take a really agressive cut until you’ve got a feel for how this handles. And plane one side, then the other to make sure that you don’t stress the plastic and get a curl on it.

It’s not unusual to see some variation in the surface of UHMW – up to 7% if the thickness variation is considered normal for this plastic.

Woodbutcher: If the variation is -.007, cutting a shim out of an aluminum soda can will probably even it up (place shim behind UMHW).
