Quote EdK:
Usually soft jaws are used with two piece jaws...
Unquote.
That was my thought, too - hard jaw bases to engage the scroll, with ANSI keyways and soft jaw tops... Then I could make up 'disposable' jaw tops as required...
But what material would be dimensionally stable enough for the bases? I can see how to mill the scroll in the bases (although with some care and a complex set-up[1])!, but after hardening I suspect all might be less than accurate, thanks to distortion - less so if the scroll jaws were case hardened?

[1] surprisingly simple geometry giving a 'teardrop' shaped tooth to engage the scroll... Bugger to set up though! May need a jig / fixture... OK, *will* need...
