I'd like to hear some ideas from the veterans on how to best overcome displays that are too close to the backglass, and are actually rubbing up against it.

On most of my solid states, there is a nice rubber gasket around the display, and there isn't this kind of wear. I am getting this action on a 1979 Williams Gorgar on displays 2,3, and 4. The lamp board itself is bowed with the center of the lampboard arch closest to the blackglass.

I moved the lock assembly back 1/4" into the backbox, and that helped bring the "edge" back, but unfortunately the lampboard isn't straight itself.

thanks,
mof

I was thinking of a few ideas, none of which I have yet tried, because they may not be the best ideas:

* sand down the yellow plastic spacers 1/8"
* install a wood rail horizontally onto the top of the lamp board that straightens out the lamp board and undoes the bowing, so when it locks in place, the left edge of the 2/3/4 displays doesn't touch.

I shaved 1/16" off each yellow plastic spacer off the left edge of each display, and that did the trick, took about 30 minutes to do 3 sets. This countered the angle of the bowing wood.

Still hoping to hear from some people how they've improved this situation. I would surely like to protect the BG. I wonder if I can throw a weather strip along the bottom edge of each display?

YES I CAN. I can finally put that accidental thin version of "beer foam" weather stripping I bought to good use. (Trust those ordering accidents you make!)

Now I feel safe once again to continue with the Backglass touchups, and not worry about them being rubbed off by the display glass...

Thanks. Still hoping to hear solutions from others in case there's a better way to move the hinge part back or something...
