Now that I've seen the mating parts and their function, I'll be far more careful. The engineering of the assembly leaves a lot to be desired, such as more finite detail on allowable corner radii and tolerances for such small features.

The lack of tolerances isn't a job killer for me because seeing how the parts fit each other is good enough. If I didn't have that info there would likely be a lot of "hand fitting", which I suspect is there anyhow.

Would it be willing to post the drawing of the long thin sight leaf in your thread in Gunsmithing section? I'd like to get input from experienced guys like Tom, Arvid and others who may have faced a similar challenge. It's not the long thin part of it which I find myself scratching my head about, rather the junction of the Ø 0.310 round with the 1/4-40 thread where it meets the 0.150" wide blade.

I have several ideas but would like others to see it so we can bounce some ideas around the collective here.
