I wasn't really trying to countersink the ends of the holes, just an attempt to "deburr" with a tiny edge break. 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.

This one of those things that were made back in the 1880's which someone took liberties with when they backwards engineered it. so some measurements have to be taken with a grain of salt, or as they say you may have to hand fit it. I was informed that even on the originals that they had to be hand fitted to make the parts work together. Plus I need something to do when the weathers cold and I'm tired of sanding on the bigger part of this project. DA

 Good one Darren, no it wasn't made by Kondia, don't think they were around when the originals were made,

David,
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. (11-24-2014, 10:13 PM)PixMan Wrote: David, naw post it where you think you need to, someone has to have an easy way to make the thing. Only way I could think of to make it was to silver solder a round bar onto the thin flat part then drill and thread it. David
