Yes, it is possible to make your own flake tobacco. In December of 2022 I posted the following describing how I make mine:
"I made a simple rectangular poplar wood frame that was the same inside-length as a flake of Sliced Edgeworth. and the same inside-width as four Slices laid side-by-side. Its overall height was 5.5-inches, and its sides were each 1.5-inches thick. The sides were joined with wood-screws. I then cut two rectangular plates of the same wood, and that fit closely inside the frame (one at the bottom, the other at the top). Each plate was 3-inches thick. Note that the plates were not attached to the frame, but free to move within it.
The frame was lined with baker's parchment, and the plates were covered with same, this to prevent the wood from affecting the tobacco's aroma and flavor. The tobacco was placed between the plates inside of the frame, and pressure was applied via a heavy 6-inch c-clamp. It's amazing how much pressure the clamp can exert, and I tightened it daily as the tobacco compressed.
After two weeks I had a solid cake that could be sliced with a razor-knife.
I hope that you find this information to be useful.
