I was working in the shop today on a little drop point, file work, meteorite bolsters and mammoth Ivory scales.
Problem #1
Once the bolsters were shaped they had to be etched on the edges before being pinned in place, no problem just etch with ferric chloride. However after the pins were peened they had to be filed flush and the surface was scuffed and had to be re etched.
Re etching a bolster already pinned on a mirror polished blade presents a problem as the ferric chloride will etch (frost) 440C stainless so the stainless had to be protected. I used heavy axle grease on the exposed 440C to protect it, worked like a charm.
Problem #2
Removal of epoxy from filework and etched bolster with out damaging filework handles and bolsters. I applied a coat of paste wax to areas to be protected, waited as epoxy hardened up fairly stiff and simply peeled off the excess epoxy. It allowed the crevices of the filework to come clean without use of solvents and needle to pick out the epoxy.
Paste wax is also handy to release epoxy from the front of wooden handles on wooden handled knives.
I guess that the heavy grease would do the same job but I didn't want to risk staining the ivory.
