Sight Parts

It’s been a while since I’ve had the ambition or the free time to apply towards building a sight but necessity tends to bring forth the ambition and desires.  I have a rifle that is mostly completed – enough that I’ve been shooting it a little and the idea that maybe I’d try it on some real distant targets inspired me to make another staff that will get me there.  The staff I have on it gets me to just about 1350 yards according to the app, but the target in mind sits about 1750 yards- according to the app now - it says I need to add about an inch and a half to the height.  The design of the sight I originally made is a simple slider, no screws, no rack and pinion, just a real simple design.  I dug around and found another piece of Damascus similar to what I made the first staff out of.   I’m changing the lug design a little but the slider design (simple) is going to remain, this way I can simply swap the block and eyepiece and continue without any issues.

To add a little humor to this story though, I was seeing a client a while back and I’d noticed a couple of fairly large nuts lying on the apron in front of their shop.  I’d commented that they looked a little rough and they’d be a fun project to tackle – making some new ones…  not missing a beat, the customer said they in fact looked a little rough around the edges and even with a small chunk of the thread missing they’d work fine for few more years.  So, the subject was dropped.  A few days following though, I got a call asking if I would entertain either repairing the lock slots on these nuts, or indexing and cutting new ones.  Not what a guy really wants but it is good work.  Anyway, I shared a picture of these little guys with a friend and the old story of some of the builds and different projects that transpire because of finding a part led to a project, like a screw that fit a Ballard and how it led to actually building a Ballard around that screw…  Was there something going to come of this??? Like a sight for a real bench gun?  I think these are a tiny bit larger than any gun I’m in the mood for but they did get me motivated.   Grin Grin

Greg,

You've got some real nuts!

I like your new idea for the staff lug.  Better looking, stronger, and maybe easier than butt soldering the staff to the lug  I may steal the idea.

Still looking for a range report on the striker Ballard.

Stay cool, John

I was thinking you were going to tell us the radius on them big nuts was about right for the curvature of the Ballard trigger plates?  Huh

Fun stuff GT... looking forward to hearing the range report!

Cheers!

Here's targets from Sunday evening just before darkness Sad  Striker Ballard, 40-70SS, GM barrel, a half wit jerking the trigger. (road weary at the time but using that as an excuse to get some trigger time)

Temps were 68°, humidity was 5% and the wind was from 11 o'clock or nearly straight on at 12mph.  Shooting off sticks at 200 yards, cheating a little because I mounted the Unertl Programmer on it.  Load that gave me the best average was 5744 pushing the 455 gr close to 1200 fps, with a single digit SD    The second load was a similar powder charge behind a 400 gr Accurate - this gave me a single digit SD but the wind seemed to play havoc on the strings.  Measured strings were 15 shots each and groups shown were fairly consistent.
If the afternoon thundershowers make it past before dark today, I have some more loads to go burn up - different bullets and different alloys to try.

Managed a few shots last night before dark and before getting  thoroughly soaked - this country has been dry so what is this all about???   
As for a range report, not much to ponder on, the Hoch 390 gr out performed the Saeco 410 gr with the 18-24mph winds I was fighting.  I moved back to the neighbor's place and shot at 500+ yards with the same loads but the conditions dampened efforts... 
 
In and amongst the sight staff build, I did a small run on Damascus eyepieces too.  I saw an oversize eyepiece one time so I thought I ought to attempt one of these also.  To the few folks that have seen this piece, only a couple of folks have asked if it’s a satellite dish for my cell phone… Grin It does make the sight arrangement a bit “clunky” and it definitely adds mass to the sight staff – heavy recoil puts the staff in motion.   It almost doubles as an eye cover for the other eye when shooting.  Wink

Nice Greg!
Is that a vernier scale I see on the rear eyepiece locking nut? Love the Damascus you got ahold of...

Looks like you're getting the .40-70SS dialed in!

What alloy 16:1 or 20:1 for the bullets??

That’s funny Bruce.  I was going to say something but decided to leave Greg alone on it!

Always fun to see what Greg is up to!

Jeff, still working on the loads - 16:1 wasn't doing as well as I hoped, recovering the bullets pointed to some issues so I'm back to a 20:1 and things look better. I'm not using a card at the bullet base and with the 20:1 the recovered bullets look better and the velocities are higher - SD's have been considerably lower Huh  - no explanation that I can really think of. 
Bruce, I think even when I get the screws in, (I'm doing them next) I'll still leave the inner tube bands on for pictures Grin  I like the mileage I'm getting from them.  Gives me some grip shooting offhand and it's distracting to others Smiley   

I did cut the vernier on the staff tonight, I'm contemplating trying something a little different on the graduations - I have the means to do small electroplating operations, all I have on hand though is nickle and silver solution, gold would look good and be easier for old eyes - may see what I can do.

Noticed the patented forearm assembly process but was disappointed to see conventional scope mounts and not a hybrid rubber band frond and u-bolt scope mount system...  Grin

The only reason I've graduated to conventional scope mounts - I got the new barrel from JerryH and he already had it drilled and tapped.  Grin   Quite a concept for me, but from this point forward I may d&t my barrels, unfortunately the scope may become a part of my shooting more and more.  Wink

Had some more time as there is an upcoming event, made some more eyepieces ready for the etching process - then call it stupidity - I started another rack and pinion sight staff - out of Damascus.  I annealed this piece three different times and thought it was cutting fairly well, the tool being in the heat of the battle, let me know otherwise.  I'm in the  process of making and grinding new tooling to finish this one... hopefully it will come together before next month???
