Actually, I don't remember off the top of my head what size the socket is. There's a brass bolt that goes through it, and a nut and washer secures it. I used an orphaned socket that just fit over the bolt.

A scrap piece of copper (left over from cutting my first breech barrel) was drilled, the bolt was inserted and the copper was hammered to fit neatly over the bolt head and contoured to fit around the coupler.

the scrap copper and brass bolt head were cleaned, fluxed, and clamped in place tightly, so it held the head of the bolt securely against the coupler. Next, I heated the whole mess with a torch and soldered the bolt and cover plate into place. Once cooled and cleaned up, I finished it off by sliding the socket over the bolt, and then secured it with a washer and nut. looks neat, doesn't it?

It's rock solid, btw. I wanted to do something a bit more permanent and attractive than the typical hose clamp thing. It was originally made for Kopperbess (my earlier build) and the breech slide was recycled and used on my current barrel. It seems to be holding up very well.

Next time I go into the garage, I'll check to see what size socket I used.

Looks very good !

And probably makes a better handle for that, than just some piece of pipe or something.

No need to find what size it is.

I was just surprised because I thought I was the only one willing to sacrifice a deepwall socket for something like that. LOL

If you can't fix it, you don't own it.

And it's not like I can't use the socket ever again, I just need to unscrew the bolt and take it off. I was actually thinking of putting a brass knob or a wooden piece on there eventually, the socket was going to be temporary, but it just sort of stuck. :D

I find many of the users on spudfiles to be very creative in terms of their solutions to design issues, I've seen a lot of innovative soldering on launchers in here.

Sorry to ask, But what are 20mm brass nipples and an flat end cap rated to(from bunnings). Would the steel malleable end cap and nipples be rated higher.

Thanks Jazzman56
