It was a frustrating day tinkering. I learned silver soldering is not as easy as it looks. Clean appears to be very very important. Temperature also. I was able to solder the guide in place and it appeared quite Stout after a couple of tries. I purchased the correct thread bolts in different lengths to use temporarily as a clamp screw and gave up trying to make one considering there is one very close available for purchase. Unfortunately I had gauged diameter and thread incorrectly. The trick was, that a bolt long enough will bottom out in apear to be quite solid. Thus I incorrectly judged the 10x24 as correct for both diameter and pitch. I'm pretty sure the pitch is correct but both old and new bolts 'wobble' in the thread if they are not bottomed out and move when clamped down on a flint.
The problem is that one has to use the top of the clamp screw to cock the rather stoudt hammer spring. If the clamp screw is solid there isn't a problem. But when the clamp screw can move the force needed to cock the hammer is transferred to the upper clamp that is held in position by guide (the one I just soldered in place). That rather considerable force on the 'wobbling' clamp screw is transferred through the upper clamp to the guide with enough force to break my rather meager attempts at silver soldering the guide back on. So I'm back to where I started yesterday. Broken guide and an illfitting clamp screw.
Being there is a suitable replacement clamp screw in 10x24, I wonder if there is a 10x24 heli-coil that i could install?
