Bob --- please email me the photos if possible.
I did manage - with some c- clamps to flatten the "tabs" a bit. Those "tabs" are a piece of metal about1/16" thick welded to angle iron of the fence that extends out to the edge where the set screws push against to adjust the fence parallel to the slots. So it's a bit of a process to try to flatten. But I did manage to get .040" flatter, so now my difference is .400-.360 = .040.
So total thickness of fence = 3.156" (open cam) - .040" (metal tab stick out) - .124" (new pad thickness) = 2.992", but my rail is 3.015 thick. And I probably really need 3.020 clearance, so I still need to find about .030".
I don't see any other way except to sand down the pads to .100", else my fence will never want to slide along the rail smoothly.
Sorry,
Got hung up this week and forgot about taking the pics for you. Will try to get to it tomorrow for you.
Got another storm moving in on us tonight - no fun...
