Ok just about to jump into a pf swap to a beautiful reproduction pf that has been clear coated. Any better alternative then the threaded nails used to hold the pop bumpers in place. I just know as I tighten up the nut the nail head is going to bubble up the clear. you do want to get it tight so the head is flush but I fears a mess with the clear. Cant I just use a #6 machine screw (heavy threads) to anchor the pop bumper? Two of the pops, the nails are behind the drop targets but the two in the middle are not. On the old pf a platter was used to minimze the head area. Suggestions?

I can’t answer your question, but that playfield looks awesome.

Cut the clear completely away from where the pop threaded screw nail goes in using a fresh drill bit by hand. Don't pound it in, either, you're better off drawing it into the PF from tightening a nut. Get some extras because sometimes they snap when you do this.... downside of harder plywood ply on the repro playfields.

Non-flush screws won't work they'll interfere with the activation platter, and you'd have no way to tighten them anyway. You MIGHT be able to use a Gottlieb style base plate underneath, I haven't explored that option yet. That would avoid the somewhat annoying finned pop screw nails. Mata Hari is on my list swap as well, but there's a couple other games in front of it that I should finish, and a couple that need to be set up. (As well as a couple prep for sale, for whenever the next show might happen in 2021....)

Is this a CPR PF? I assume it is. I use a caliper and drill the hole slightly smaller than the nail. I use a counter sink drill bit and drill a hole about the size of the nail head. I do hammer it in and use flat punch slightly smaller than the nail head to drive it in flush. I've done about 10 of these and have never had a problem. Feel free to contact me if you have other questions. Good luck.

I use these diamond bits for a dremel. You can buy a kit from Ron Kruzman

Alright Im wimping out and will just use a #8 stainless sheet metal screw to mount the pops from the bottom. I just dont want to mess up the beautiful irreplaceable pf.

I hate to be negative, but they will probably fall out. I'd say that's why there are through-hole fasteners like the pop bumper screws to begin with

The diamond bits are easy, especially will a variable speed Dremel set to low speed.

ok pf was not cl coated after all, borrowed my neighbors coutersinking bits and countersunk until it equaled the size of the head. all good.
