I'm concerned that there's no 'stop' and I'll crush the plastic. The plastic
parts are vacuum-formed and will already have a fair bit of work on them
before adding the metal parts, so I don't want many failures.

Make your own rivets. Turn them with a shoulder the same length as the
parts they have to hold together plus an allowance for clearance using a
washer with the same bore as the diameter of the rivet up to the shoulder
riveting all three (plus) parts together.

Why not use a pop rivet, I can help you with 200 and lend a tool if
needed.

I've got a pop riveter, thanks, but these want to be shiny pan-head
rivets for appearance as they're highly visible. Pop rivets just
aren't the same.

Hello Adrian this type of rivet used to be called burfacated rivets
and they used to be used on brake shoes for holding the linings on
they used to spin rivet them using a high speed rotary tool with
pressure applied downwards such as on a drill press I have used these
many years ago but you need to try different sections on the rotary
tool but in principal in section the tool looked like a inverted 'W'
hope you get the job sorted Cheers Colin
