Hello everyone I'm new to this forum and need some help. I'm a welding major at the local community college in Honolulu. We have 3 projects to do in our shop and hand tools class. The first was make a cold chisel out of 1" diameter round stock, shape it harden it and temper it. That went fine for me. Now for the second one with a 1/2" diameter round stock shape a center punch the problem is after shaping it with the point on the end then heating to a bright orange and quenching it in cold water fast the using 400 grit sandpaper to make it shinny, then heating it again watching the color band move towards the point when it gets to a blue color then cooling it in oil. Then the test pound it on a 1" piece of steel the point just flattens out to a blunt point and leaves no make on the plate. What am I doing wrong? Thanks
