said it actually works! LOL

A fellow for whom I've been doing a bit of airgun parts work told me about his Gamo pivot bolt seizing up so tight that it was pretty much destroyed by removing. As I understand, Gamo doesn't sell replacement parts, so I offered to attempt fabricating one just to see if I could do it. The issue is that the head of the Gamo pivot bolt has a 1 degree taper, as determined by measuring the bolt and laying it out on my CAD software. With such a shallow taper even relatively minor measuring/fabrication errors would make the bolt unuseable. are a few pics..........

Fabricated bolt and damaged factory bolt with sleeve.

It was a bit of a tedious project for a "seat of the pants" machinist like me with a bench top lathe and dial calipers, but it was also a fun project!
