Re: UHMW Fence question
Use the two screws in tandem to get the slop out of the fence, and then use them in opposition to adjust the toe-out on the fence. For example, if you're using the fence on the right side of the blade, and want toe-out, you'd loosen the right screw a smidgen and tighten the left screw a smidgen, and then check it. Make a tiny change and check it, and then make another tiny change. I found that a dial indicator works great for this. Harbor Freight has them for about $10, with an adjustable magnetic base for another $10. I used the magnet to stick it down to the miter bar on my incra miter guage and then slid the gauge in the miter slot to compare the front and back ends of the fence.
And as for adjusting it, Ive tried to get a little toe out, but once I have some, the set screws are so far in its hard to slide the fence. if I back them out to be able to slide it again, I lose the toe out.....and I also want the screws in more to prevent "slop" when sliding (when the fence is so loose on the track that it gets stuck between the front rail and the front rail bracket).
