| Hardening or case hardening how too…. |

| Jasonb:
Your observations would seem right, the softer surface clamps start to gaul and the friction goes up, the hardened threads will slide against each other allowing more tightening force to be applied. If you really want teh DIY approach the old way was to use bone or leather rather than an off the shelf powder, the part was packed into a container (Large tube) with teh bone dust etc around it and backed in a fire at red heat, the carbon was absorbed into the metal.

Anthony can you cut a small area off heat it up and dunk in to something cold. See what happens with a file before and after? Dont worry about temering purely to see whether it hardens. It wont be anything precise far from it but at least you would know whether it would take to through hardening. If that is the case it could be trial and error diy, too hard or too soft etc bit too risky. If not case harden. |

Johnny. Great idea, I have plenty I will cut off a 2” slice and do as suggested. Going back to one original question I had, when you machine a piece to a tolerance like a thread ( male or female ) will the hardening/ heating process effect the fit? If so is there a rule to sizing?. Jason. I have access to a ton of bones where I live here on the farm , you have given me a little project to do to see if I can case harden that way, I will certainly record my results and let you know. Many thanks to all for your insights. Anthony. God bless |

Case hardening will add a minute amount to the surface, not really worth worrying about. For something like a clamp thread I would give it a bit of play rather than making it a dead tight fit. Jason |
