Here is my Chess Pawn experiment.
1. Got the flashback controller and decided which pieces might work
2. Tried each of them on the disc and discovered the pawn was the perfect size.
3. Removed the felt from the bottom of the Pawn, set it in a small pool off goof off to remove the residue. After 5 minutes i wiped it off. Then i took the pawn and raked the bottom across 60 grit sand paper to give it a surface to grip on to.
4. Took a heat gun after the removed disc. Heat gun caused it to curl in very little time. Removed it to reveal a clean surface. Put goof off on it, let it sit and then wiped it clean ( had to do this 3 times to get all the goo off). I then took 60 grit after the clean disc, again to give it a rough surface.
5. Took the two tubes or original JB weld, mixed them and applied to the bottom of the pawn.
6. Applied the pawn to the disc and set in a plate with a paper towel because the disc can not lay flat.
7 After 24 hours i reinstalled it to the controller and played about an hour of games.
The stick takes a bit of getting used to if you grew up on the old controller. But all in all this will be a good solution for those wanting a disc.
You will notice the disc still shows signs of scuffing outside of the bottom of the chess piece. I may take some glossy model paint and touch it up to match. Its just a cosmetic thing.
