OK.
Plastics polished edges.
Transparencies printed and backs painted white.
Plastics affixed to transparencies with varathane.
Will take a week of dry time before I can futz with them.
I am not going to drill out the holes as it is a pretty tight placement on my game depending on how your ramp is and the posts it sets on, so easier for each person to drill it out yourself for exact fit.
I suggest overdrilling slightly (helps to keep if from breaking it it has a little play) and drill from the frontside. Go slow with pressure but high speed rotation on drill (almost melting the hole as you drill); do it with the plastic firmly placed on a piece of paper on top of a piece of wood to keep from scratching off paint on backside and also for an optimal clean hole (everyone likes a clean hole).
I will post some photos after I get the camera charged.
