Two more thoughts on creating a shallow popper cup:
- Sanding: Cut a 4" ring through 1.5" thick hardwood with a hole saw, mount it in the lathe and use the Vega template to shape the curve on the outer face of the ring (this would be like taking the middle slice of a 4" x 5" oval). This still requires attachment of sandpaper, some kind of jig to hold the popper, etc. Winter.
- Burning: For $20 (including shipping) I ordered a hollow stainless bearing, it's 3.5" in diameter. The hope here is I can place it in a vise, run a torch on it and press a popper face into it for an even shallower cup than the carriage bolt head. I might even risk squeezing it in the vise to deflect the shape into an oval. Probably my last popper cup experiment this spring.
