You do excellent work sir. As for the shroud, breech, tube mods... that's way above my pay/skill grade but you made an incredible shooter there.
Nicely done and I really love that black walnut.

Its a little to late now but you could have just used a Prod end cap and saved some time drilling for the Prod breech by only having to drill the valve or could have used a prod valve and just had to drill the tube but it looks real good and MAN that stock is awesome and actually thought it was a custom made Boyds stock.

You could make some extra cash in woodworking with art like that as its almost to nice looking to actually handle to shoot but we already know that aint going to happen. LOL

Kudos on the build and hope you get the magic number of 825 plus you are seeking as I am sure it will happen with some more time and tuning.

thank you buldawg. we will keep poking at it. gotta make some more SSG's for our other guns. im sure my bro will want one too.

Buldawg76 · « **Reply #110 on:** March 13, 2016, 03:05:54 AM »

Yep we never can be caught up with our projects since we would not know what to do with the free time or well at least have to think what we would do with it. LOL

I to was a mechanic for 45 years as well and if my hands are idle I don't know what to do with my self.

Beautiful stock and nice looking compact SSG. Well done.

David
Does your SSG stay completely inside the rear end cap of the tube and just compress the spring on the guide so that it free floats when fired between the end cap and hammer as I cannot see where you have a hole drilled in the rear end cap for adjustment or to contain the SSG from free floating inside the tube.

If that how it works I like that idea so while it may take more to adjust for tuning once set you don't have any guide or nuts sticking out the rear of the gun. is that a 1/4 -20 bolt for the guide and if so how long is it and what spring are you using I.E. wire size and diameter and length with how much preload.

David
Just reread the thread and saw where you stated the spring size and preload on it so would like to know the bolt size you used for the guide.

Mike

David Mccann · « **Reply #116 on:** March 13, 2016, 07:42:45 PM »

yes sir, it is a 1/4 -20 x 3".. i had to tap a few more threads to get my preload tight enough, still needs a little more. the nut was threaded onto the bolt and turned round, instead of leaving it hex shape. my rear cap required boring inside with an end mill in the tailstock of the lathe. i bored it .030 larger than the now rounded nut, and deep enough so that a .040 "rattle" gap was created when all was assembled,rear cap in place, and uncocked. i then found a soft oring that would take up that gap ,dropped it into the rear cap, reassembled, leaving no gap, but i could push the hammer-ssg assembly rearward and compress the oring to create the small gap. the gun is soooooooo quiet. this is a reggd setup. oh yea, turning the nut round removed the material holding the nylon lock, so now its not a locknut. i used the disc sander to make 2 flats on each side of the nut and the end of the rod that hits the valve, so it could be gripped with open end wrench to tighten together. i removed all excess thread to the nut. because i had to cut a few more threads, the nut was screwed all the way to the unthreaded shoulder, so no threads for the spring to interact with , so the movement of the spring- hammer- ssg rod, all move very smoothly and consistently. applied blue loctite before final assy. hope this helps. cheers ,david

David Mccann · « **Reply #117 on:** March 13, 2016, 08:30:42 PM »

it stays completely inside. the hammer just slides along the ssg rod, as the rod passes thru it

oldpro · « **Reply #118 on:** March 13, 2016, 09:39:18 PM »

The only way to do it as far as im concerned. Safe and effective.

Dairyboy · « **Reply #119 on:** March 13, 2016, 09:43:53 PM »

Yeah I'm going to try to make an internal ssg for mine as well. I bought the WAR SSG for my Mrod and being one of the first ones mine came with a strong and weak spring. I figure that weak spring should work just fine on a .177 disco.
