    One of my clamps on my alpha pioneer DC plus could use some tightening up. To lock the base, I have to turn the lever way to the other side. I would like to tighten it so I can lock and tighten the base easier.

    Does anyone know how this is done? the manual said to insert an alan wrench into a hole in the base and tighten, but I tried that and 1. It didn't seem to be entering into a socket for an alan wrench, so it was having no effect and 2. I wasn't sure if that was actually the method for making the locking mechanism tighter.

    Hi Hunter,

    You need to make sure the base is turned perpendicular to the rails otherwise the set screw will not be available to the Allen key .

    There was a thread here a while ago that had detailed photos of the clamps I also provided a response to that about the best way to tighten the bases.

    Let me know if you still have problems.
