    Is there anyone out there who can take my melonite(salt bath nitride) bolt and cut the knob off and thread for a badger knob?

    Thanks

    Which action? Being melonited is not an issue so anybody that can thread bolts can thread it

    Kelblys told me that nitride takes surface metal to a Rockwell 60 hardness if I remember correctly. I tried to use a new, sharp deburring tool on an action once, it put grooves into the deburring blade, and didnt touch the action.

    You can cut it with carbide, but if you get aggressive you may shatter it too. I think to thread a bolt handle knob, you'd have to grind the surface coating off before trying to thread it. Maybe the average machinist may know these things, but I know kelblys cautioned me about it.

    Not saying it cant be done. Just making sure the warning is understood.

    Melonite is case hardening of about .0003" thick. Get below it and you're good to go.

    My bolt handle on my HS Precision rifle had the bolt melonited And when the gunsmith tried to thread it on the lathe it broke of the bolt. Had to be brazed back or soldered. Threading the handle had to be done on a endmill. Gunsmith did tell me that HS bolts are hardened.

    Ive threaded melonite barrels, fluted them, rechambered them, fluted bolts, opened up dies and all sorts of other operations on melonite. Been messing with it since it hit the scene and joel kendrick ran the first batch of barrels. Trust me youll never know its there when machining. Like butch said its not even a half thou thick. If somebody had issues with it- it wasnt the melonite that did it. Send it on over to carlsbad- he knows the secret to machining it too. We dont know which action it is yet but if he has the fixture itll take the exact amount of time it would if it was in the white. Its for wear resistance and its a surface case hardening. It doesnt transform the steel to a super metal.

    Victor, I sure wish that you had it micro-tigged instead of braze-solder.

    Hate to call a guy out but the bolt wasn't fixtured correctly if the handle was broken off. Indeed, it is hard to hold a bolt if you don't have the right fixture. I don't have a fixture for right angle bolts and I turn down those requests. A better option would be to remove the handle and solder on a threaded handle from PTG. You can adjust your extraction to perfection while doing it.

    Tig welding the handle on is not the answer.
