I can't remember how I formed the recess in the middle...
yeah the rubber backing pad is still in place, its been a while since I used it and the heat build up wasnt an issue, the disc didnt get warm, but that could be because Im not the worlds fastest workerThis would work: put the flat disk over the end of a piece of pipe, bowling ball or something with a convex end on top, apply hammer.
It is not so clear from yours, but is the rubber backing pad still in place? Does the heat affect it at all?

I do that , but they smell ,,,I made mine out of a piece if 1.2mm stainless steel
I cant remember how I formed the recess in the middle, it wasnt anything complicated and I dont have a press. the shrinking surface was dome done with hammer/dollies/slapper.
people have also used fibre sanding discs the wrong way round (using the backing face against the metal) to create the heat.
I like the big one but it is scary as it goes on a 9” grinder. I used the small one to take a load of tin canning out on a roof that had been sand blasted so works but is just slower to build up the heat. You’d manage both jobs with the smaller one and is probably better to learn with. I welded in a rear arch and a large patch in a rear quarter and I put a bit too much stress in the panel when fitting it so it was high in one area at the top so I used the big disc to shrink it back down, took longer than expected but I got it lovely. Good tool to have.@Burdekin which would you use more? I've two areas that I'd like to use it on; the rear light panel has an 'outey', presumably from something sharp in the boot hitting it, and the quarter panel has a bit of oil canning above the wheelarch (and area about 6-8 inches wide). Worst case scenario I can knock the first one in and fill it.
The second is a low area that will need to be knocked out before I can do anything and access is restricted. Anyway, I'm babbling....
Polishing mop to convert?i think a 6 inch one would be mighty handy , and a good reason to but a 6 inch grinder on its own , although I have one six inch flap disc I was given ten years ago ,,,,, not quite enough reason to buy a nice high power vari speed six inch grinder ,,,,,
but now its looking like I need both ,,,, its been mentioned before but this place gets expensive ,,,,
Stakesy’s are out of stock, and I’d stay making my own would be outside of my skill set…
I might cut my losses and start again but in fairness it didn't take long so it's no big deal.
