John B Posted November 5, 2015 Share Posted November 5, 2015 Held a toolmaking day at Westpoint Forge last week, explained basic heat treatment and how to do it in the forge. All items shown are in as forged finish, file and emery cloth to clean up for tempering Made a hot cut chisel from an old farriers rasp, annealed, forged to shape, and can be used as forged Hot punch from a coil spring, use as forged finish. Cold chisel as forged, Struck end being forged to a chamfer to help prevent spalling, Chisel's cutting end forged finish and lightly polished pre harden, then again after hardening so tempering colours can be seen, Centre punch as forged, struck end chamfered to help prevent spalling The picture of the centre punch I hope shows the tempering colour band Quote Link to comment Share on other sites More sharing options...
