kjohn: I have been well received here. I have found that when you broach the territories of so called "experts," feathers will be ruffled. I just left. I was actually chided for "Arrogant Backchat!" I did not know that such a thing existed? oh well,,, live and learn.
RRco: The gun is working very well with the new trigger pull and the rear sight. My Cast Boolit loads are not performing as well as expected so more work to be done there. The rear sight answers inputs exactly at 100 yards IE; 1" needed movement Equals 1MOA on sight exactly. I was very impressed with that, as other sights on my guns don't always work that way.
The thing is a joy to shoot and all I have to do is get it to deliver Cast Boolits in something resembling a group. I just ordered some Prvi-Partisan 150gr Factory ammo and will see how it shoots with jacketed bullets. If it shoots jacketed bullets it will shoot cast as well, just a matter of finding what it likes.
On the Enfield's 29" sight radius, a movement of either the Front or Rear Sight of .008 Equals 1 MOA at 100 yards. So any Screw Thread Pitch that is divisible by 8 or 2 is very easy to translate into a predictable move. A 20 pitch thread would have yielded about 1MOA per flat, and I felt this was too coarse. 40 threads per inch would have been 1/2MOA per flat and nearly ideal. Unfortunately there aren't any common thread sizes with 40 threads per inch that are big enough diameter to be practical for this application. The 1/4-28 thread pitch yielding 3/4 MOA per flat was the best choice for this application. IE: commonly available screw. I also used a Thread Forming Tap as opposed to a Thread Cutting Tap so the threads would be stronger.
The tool is being looked at by Brownell's as we speak, and they sound enthusiastic about it. I will also be making a spanner driver for the grub screw on some of the Enfield #4 Front Sight Bases so a guy with one of those can have a decent tool to loosen and tighten that screw properly. So far the feed back I have gotten on the product has been all positive and no one has had to make more than one move to achieve their desired result. The whole idea from the beginning was to make this tool as simple as possible to get good results from.
I will probably make some small cosmetic changes to the production tools like laser engraving the company Logo and maybe a reference hash mark, and a note stating 3/4 MOA per Flat.
You should put your original tool in a safe place so it doesn't get hurt, and use one of these instead.
