I just installed a repro "Gold Strike" backglass into a game I'm bringing to the White Rose show. It didn't want to fit width-wise. I laid the new glass over the original one, and saw that it's about 1/4" wider. It is also thicker than the original one.
In order to make it fit, I began to chisel off the small wooden block in the backbox, which stops the glass from moving to the right. I must have tried fitting the glass at least four or five times after each round of chiseling, but it still wouldn't go. Finally, I removed the plastic stop on the left inside edge of the back box, which is held in by one screw. Now, the glass fit. I noticed that the plastic stop had a taper to it which corresponds with the taper of the wedge head lightbox. So, I slid the wedge down along the left edge of the backglass, until it rested snug again the glass. Then, I marked a new hole for the screw, removed the glass again, and reinstalled the plastic wedge slightly above where it was originally. Now the glass can't shift laterally, and luckily the alignment with the score reels is perfect.
As I said, the new glass is also thicker, so the lightbox insert fit very tightly against the glass when I swung it closed and locked it with the lever. I guess I could have used some washers behind the hinge brackets to give it a little more room, but I'll leave it snug.
Just thought I'd share this, and has anyone else here had problems fitting a repro backglass into a game?

Yes, I have had an issue with a reroduction BG before size-wise. Not for thickness. Who was the supplier of this repro backglass?

Well the good news is it didn't break in the fitting attempt.

Was this glass done by Ron Webb?

I've had this glass for a while, and am not really sure where I got it from.
I know I didn't order it from Ron or Shay, but I think I got it from a dealer or collector. I did bring it to the attention of Steve Young, and he said he's heard about this on repro "Gold Strike" glasses. Not to lay blame, but I believe it's a Shay repro. Also has haloing around the 100,000 and above the score reels. The original is pretty bad, so I'm not really complaining, just pointing out some QC issues which will hopefully be corrected in the future.

No, but I felt like I was pushing my luck every time I had to handle the glass! The fact that it's thicker than the original is actually a good thing, but keep in mind that it might need a little tweaking to get the insert to close without excessive pressure on the glass.

Sharing your feelings on handling a back glass.

I have had it happen with reproductive glasses, most recently with a Ron Webb Jacks Open glass. I removed the plastic piece and left it off. The fit is so snug I didn't think it was needed.

I find this too weird. Its not hard to measure to within a 1/16 th of an inch. How is it even possible that someone would spend the time to generate the art and cut the wrong size glass! Is it the case that originals vary substantially? Seems not unless they sat down with a pile of glass on the assembly line and sorted through until whichever one they picked up happened to work with the head on the production line. That seems unlikely....

So what gives? Amateur hour or expected variation? Just curious.

Amateur hour. The old carpenter saying of measure twice cut once applies here. I won't name names but one back glass make had to eat one because his contractor measured it incorrectly. And the art was on.

JR: have bad a couple games where glass fit tight due to thickness and in one case it scratched the glass. So put thin felt pads on glass where it was opaque. Protected the class well.
