Stop screw Empty
PostSubject: Stop screw   Stop screw EmptySat Oct 17, 2009 11:38 am

I don't remember my 7410 having one, or at least, I don't remember dealing with it. My 2410 and 2400 have one, however. I assume that it limits the trems action in some way, but how and how does it function?

Correct-a-mundo on all counts, Martin. The first Kahlers did come with a small stop screw that threaded downward through the back of the cam plate. It was meant to be adjusted to hit the bottom of the wood routing pocket in the body of the bass, so that the trem's return point could be controlled in that the screw prevented the cam from coming back beyond the point where the screw hit the wood. This way, you couldn't pull up on the arm, only down. This meant that the trem didn't float. It would only drop.

My first Kahler's had them, but they stopped putting them in after a while. Why they did, I have no idea, but I imagine that it had to do with the fact that the screws had a tendency to bend and break after a while from the pressures being exerted on them from the cam pressing them into the wood. I kept the one in my first Kahler for about six months before it started to bend, then I pulled it out, and never used them again.

That's the cam tension adjustment screw that sets how far forward/backwards the cam sits, as well as the amount of drop or upward pull the Kahler will travel, and every Kahler has one. But I think I can see the hole for the stop screw in your picture. Look on the right side of the flat portion of the back/bottom of the cam, located below the right arm hole. It's a really small thread. Either that's the hole for the screw, or it's a ding in the metal.

Stop screw Cpic001x-6

and yep, that stopscrew was digging into the wood for all those years, and yep it is also slightly bent. I'm gonna clean up the trem and the bass body a bit before I put it back together.
