Wonder if this device would be useful

[BigFoot]

Just stumbled upon this and thought it could be useful on damaged rubber etc. What you think?

Could only use it once maybe twice, even then I don’t think it would give same results

Meant to be absolutely horrendous

I believe Sorbo did a system like this. That's why their channels have 3-4 positions to set the rubber. It was horribly expensive though, and needed a stable table and a small beast of a machine only to save a few quid on rubbers. Looked into it 10 years ago so my memory might be spotty, but found it was not worth it at least.
