I have a broken 6/32 tap, about 1/2" deep in a thru hole, material is O1 tool steel. I understand that if it were a bronze, or similar, I could toss it in Alum and eat it out. Any ideas for getting it out, poormans homebrew edm, acid, or ??? It is a part for a model steam locomotive, Stevenson valve link. I would really like to save it, as I have a lot of time in it already. :bang: Any thoughts, or help, would be appreciated. |

carbon steel or HSS tap if HSS you are in deep do do ddm is possible if its carbon steel tap heat the part to red heat and let it cool ( if you have a BBQ light it up and toss in the part leave it online till next day ( i.e. cool very slowly in the ashes ) and you may be lucky and it will have softened enough t drill out with a carbide drill for lightly loaded threads try using less thread depth ( bigger drill by about 0.1 mm bigger btw how big is a 6/32 tap anyway Stuart |
