Hi again,
I tried again to work on the SMT. I loosened the 3 appropriate nuts on the SMT base. I had the front rail clamps in the locked position and solid. I had the rear clamps loose.
I have a question that I hope someone may be able to answer
The smt clamp assembly is made up of brackets, cams, and an aluminum u-channel that pushes against the larger rear rail to lock in place. When my rear SMT clamping assembly is loose, the whole clamping assembly has approximately 1/8" play if I wiggle it front to back (between the underneath u-channel and the larger front or rear rail--more so in the rear). I know there is some room necessary. Does this sound right. The reason I ask is that when I go to align the SMT base, the whole clamp assembly ends up moving along the larger rear rail before I get any movement on the smt base itself I am wondering if this excessive play is part of the problem. I would guess that with the rear clamps open and the front clamps locked, I can easily move the SMT base an inch left to right without putting any real pressure on it. Think of it as the rear of the SMT base "torquing" against the front clamps
I have not been able to figure out how to keep the clamp assembly from shifting while adjusting the smt base or while tightening it. The only way I can get the SMT base to move is by holding the clamp in place with pressure.
I wish I could post some pics, but I didn't have any luck with that. My words probably aren't very good descriptions on this, but they are the best I can do.
I can't tell you how frustrated this has made me
