Gday all, The job at hand, sharpen a miners pick.
The work sofar:- made a set of hammer-eye tongs with a ring to hold the pick head while working on it(I can supply a pic if you want one). Drawn out the points on the pick so both are longer and sharpish - its not a surgical instrument, so it don't have to have a fine edge. Hardened both points with an oil quench - I didn't want it to be too hard and brittle.
Ok, so now the question. What colour should I temper the points too?? I've looked in my selection of smithing books and can't find an answer. Has anyone here done this job before? What colour did you use and how did the tool hold up after tempering?
Kind regards Rusty_iron
