[GreenKeys] More 28 reperf hammer head

[Bruce Gentry]

I have an idea for getting the hammer made. Does anyone know if laser 
cutting is available for rubber?  The thought is to get a chunk of tread 
rubber from a discarded  tire, and get the rectangular slot cut into it 
with a laser. That is difficult part, the rest of the shaping can be 
done with a grinder and/or razor blade. 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.
