[GreenKeys] More 28 reperf hammer head

> The other possibility would be to get a small piece of uncured tread rubber from a retreading shop, shape it around a correctly sized piece of metal to form the slot, enclose it in a small sheet metal mold, and then bake it to complete the vulcanization. It could then be worked to shape and size with a razor blade or grinder. I think tire tread rubber would stand up to the job quite well.<
Could uncured rubber be forced through an extruder, to make hollow rectangular rubber noodles that could be cut to length & cured??  For that matter, I wonder if there's some business that does custom extruded material like that economically.
