Best way to secure trophy plate to cylindrical cup base??

[cobblers.keys]

What is the best way to secure a 4'' x 2'' trophy plate to a cylindrical bakelite cup base? The one I have come in the shop has got double sided tape sticking them together but it's "sprung off" one side. It needs to be engraved each year with next winners name and year etc.

Either screw it on or use long nails and fold them over on the inside

Thanks count, do you know what the long nails/pins are called so I can get some? Standard trophy pins aren't long enough.

[Count Muppet]

I don’t know

i thought they were just called trophy pins

maybe you can use the ones that you can get for sewing?

Good idea. I managed to use a Dremel drill bit due to small hole required and use  standard trophy pins.

B&Q sell frame fixers, one in each corner should sort the problem.

I usually bend around the long last, which over bends it and then it snaps into position
