Ok, so I have a Porter Cable 270 Table saw, the model they carry at Lowes right now. I’ve had it for a while, and decided to check its alignment. Well, the miter slots are parallel to each other, and there is about .002” difference to the blade. The fence however is about 40 thou off from front to back, leaning to the left more in the back. I perused the manual and Internet, and cannot find how to adjust the fence independent of the front and rear rails. There are no adjustments that can be made of the rails either. Does anyone have any suggestions as to how to resolve this problem? Yes, my measurements are quite accurate, and it is both miter slots reading the same 40 thou. The section of the fence that spans the blade accounts for between 9 and 10 thou. Thank you for any suggestions! – Rich

Rich – If there are no adjustment screws on the fence, is it possible to shim the fence at the t-joint that contacts the rails? You could try shimming the rails too but I think it’d be easier to shim the fence. You could also add faces to the fence and shim the faces.

You might also consider selling the fence and adding a Delta T2 for ~ $155 shipped from Tools-plus. It’d be quite an upgrade IMO for not a ton of money…..and it’s fully adjustable.

Haha! Thank you Scott! I installed a sacrificial fence on my PC fence, and then shimmed it with masking tape until it was within specs. The best I could get was ~4 thou, but that is acceptable for my uses. I was able to rip a piece of 1x pine to exactly 5/8, as measured with a digital caliper. I can’t say thank you enough Scott! – Rich

I have the same saw I got when it was newish 2010 DEC , I have had to take it into the shop because the blade elevation wheel mechanism was slipping bad, a worm geat or trunion was stripped and had to be replaced under warrenty thank the Gods , now as I am tring to miter a box the bevel only goes to 44 degrees and that is not acceptable and I cant figure out how to adjust the stop , or fix it, it should have been adjusted at the service center when i had the part replaced grr, any ideas ?
