Recently I had a 98 bolt shortened to fit a Model B Kurz sporting action. The work was carried out by a reputable smith who has done excellent work for me in the past, including new bolt handles, as good as any I've seen. His approach to shorten the bolt was to cut the bolt between the rear lug and guide rib, and tig weld it. He had to re-harden the cocking cam.
I am currently discussing the result with him as although the bolt functions, it is not "slick" and appears to have the slighest bend/bow in it. The bow is apparent more by eye than measurement, a straight edge does show some waviness but nothing definitive.
I now want to have a go myself, I have some friends who are first class machinists who will do the actual work. My thoughts are to try cutting a bolt through the guide rib, index a socket joint from the inside of the bolt and silver solder the joint using the guide rib to ensure alighnment. We would ensure heat applied is minimal and does not reach the ends. I think I would have the bolt handle done first so the bolt doesn't have to get hot again after the shortening process.
I am interested in feedback and other ideas/approaches.
Thanks
