    I have found that my zero drifts rather rapidly. I have determined that the problem is caused by slight vibrations on the bench causing the adjustment screw to change position.

    Any suggests about how to increase the friction on the threads while still allowing adjustments to be made without a lot of work?

    Thanks.

    Put the scale on a firm counter and zero it. Then dribble a little melted wax from a candle on the zero adjust screw so it doesn't move. If you need to change it, wipe the wax off.

    Are you weighing a charge and then seating the bullet in the case? Is that the source of your vibrations? If so, why not charge a group of cases before seating any bullets?

    You might consider "hickeying" just one thread, just a wee tad. This would increase the friction, but not make it hard to turn. Gotta be careful, of course.

    As for the idea of the candle wax, you could scrape some into the threads of the screw and see if that helps...

    Good luck,

    I'd call the good folks at R.C.B.S. about a replacement screw; it might also be worth your while to set the scale on a piece of wood or stiff cardboard on top of a piece of foam rubber to absorb vibration.

    A few wraps of teflon tape will remedy that problem. For about $0.29 you can get an entire roll that will last forever and work on many many gun related things. Look in the plumbing section at any hardware.

    I use teflon tape, too. The best remedy I found was to mount the scale on 16"x16" patio stepping stone, and place it on a separate stool that isn't connected to the bench in any way. The extra weight helps defy wind currents, floor vibrations from the stereo, and accidental bumps.
