Most of the flashers are better for brightness after reflowing all of the solder on the fuse board. The cold solder issues on these games sure haven't been exaggerated. Still trying to figure out what is up with the teleporters. If anyone has any ideas I'd love to hear them.
No, I got it out of state.
As for how the dice were mounted, I'll have my husband explain, since he's the one that did it:
Found some sets of vintage dice on eBay (GameScience dice, to be exact). Newer dice are made of a much harder material, so no idea if this could be done with them*, but the terrible plastic used on the old dice is a bonus here, because it's soft enough to use the post to thread it, and the act of compression when threading will make it hard enough to stay on (I could not pull the die off by hand no matter how hard I pulled). After painting the numbers with white primer (I didn't have a crayon handy), I drilled a hole partway into each die one bit size smaller than the post (be warned, there can be air pockets in the die, so go slow and be careful), then using a fair amount of force threaded the die onto a post held in a pair of vice grips, then transferred it to the post on the playfield.
*and curiosity got the better of me. Tried drilling and threading three newer dice, pictured below. The two on the left worked perfectly. The one on the right was MUCH harder to drill, powdered as I drilled, and chipped a little when I threaded it, but stays securely on the post now, but I'm pretty sure an airball or two would take it off. Anyone want a few dice with holes in them?
