This thread is VERY relevant to my needs.
I have a High Standard Military HD for which I bought a lot of replacement parts from Brownells and the new High Standard such as springs and specifically a new extractor. Once I actually got to shoot it I discovered it became a jam-o-matic. Seems the new High-Standard extractor is oversized on the inboard and outboard sides and has deformed the chamber wall adjacent to the extractor cutout. It has also created a bulge on the side of the slide but I think that can be gently tapped back into place. I will file down the offending proud extractor material but I still need to push the chamber wall metal back out so rounds will chamber once again. But apparently the Menck chamber iron tool is no longer produced. So, I would also really like to rent, beg, borrow or outright purchase this tool so my HD can be a shooter once again. Thanks in advance, Eric |

Made a number of them over the years.
Likely they are still lurking in a box in the shop. A piece of oil hardening tool steel rod and lathe lets you do a lot of things. I put a taper on them based on the divot size and length of chamber. Harden after machining and polishing. Gently tap in, put brass rod up barrel and tap back out. Check burr. Repeat if required. |

@eric10mm
A gentleman on CastBoolits let me borrow his. I emailed him a shipping label and promptly returned it, after usage. @brickeyee I was going to make one, but I've never needed it and don't see myself needing it again (the burr came w/ the used gun  )
If, in the future, I have a need, I'll turn one out. |

If you have a lathe, or any machine, you should have a machinery handbook. In it will be hardening techniques.

Make sure you have a decent hardening technique. What can I do at home? I have a MAPP torch but no oxy/acet. |

Quoted: Make sure you have a decent hardening technique. You need to know what quenching medium the steel is made for. Water, oil, air. The air never seems to get as hard as I want it though. Water and oil usually come out well. You can increase the odds by putting it in a gas oven at the highest temp you can before hitting it with a torch. IIRC I did not then temper it. Used it as hard as I could get. It should not need all than much hammering to set back a chamber divot in a .22 RF. I used a 16 oz dead blow and a few taps. If it has a smooth polished finish, some lube, and a gentle taper it is easy. Pop it out with a brass rod from the muzzle. |
