Porter Cable 4212

I have problems with the PC 4212 dovetail jig. Specifically cutting the PIN boards. I can cut both TAIL boards on the left side of the jig and they will be perfectly lined up. To cut the PIN boards I need to use both the left and right side of the jig and therein lies the problem. The two metal adjustment plates (left and right) must be aligned perfectly. My right plate was off 1/50 of an inch and that is enough to make the joints uneven. My problem is when I tighten the hold down screw with the supplied Allen wrench the plate moves just enough to move the plate.
Please do not reply unless you are a user of the PC 4212. I can't afford the more expensive jigs.

Thank you, dkt
