End goal? Enjoyment, and functionality. It is a really interesting question though as sometimes the build is directed by what you can do, then as you get more confidence it changes. For example the latest one I made the breech myself and it has it's quirks, but on the next one I know better what to do.
I don't plan to change colour, but have wondered what home anodising would look like, but quite like that semi polished alu with black or walnut look. Giving them a polish seems to harden the surface a bit too and they don't mark as much as unpolished. They are both the same tank size and calibre. Latest has a shorter barrel. Yea, I will try the stock on them, as I am keen to see what they go like at longer distances too. I will put a rifle scope on also as the pistol scope is challenging to use.

looking good Pauly.
Like the breech on second. What's the size difference compared to original. 10 ft. Lb is a good amount of power for a bird gun. Fancy chucking a stock on one and testing it out to 30m? Be keen to see its accuracy when it streaches out a bit. Whats the end goal? Hunting pistol, target pistols? Decided on a finish for them or you they stay metal?

If it's anything like the last build, 2000 psi seems to be best for this unregulated setup. More pressure and the hammer can't hit the valve hard enough the way it is, and the first few shots are really slow until the tank drops in pressure, so it's a waste to go higher.
So I have now dissassembled it and have washed everything to get rid of any swarf and oils. It's amazing how much work goes into this. Each of the caphead screws that retain the valves has been turned down to perfectly fit the hole and countersunk hole in the valve blocks. This means no movement when the tank is pressurized and they all bear the load equally. There's more, but that'd get boring. All clean and dry awaiting refitting. |

Haha, yea, I have an old school note book that I write stuff in. Sometimes you have to draw it to figure out what you plan to do. And so that you don't forget it.

I completed the main part of the build tonight.
The bolt is spring loaded, so you pull it out then back to cock, and it'll lock back in when you push it forward. I made a steel plate for it to ride on rather than the stainless chewing away at the aluminium. I also cut dovetails into the top. I will be putting it onto a different trigger frame with walnut grips, but it doesn't look too bad like that and it functions. I still need to pull it all apart, polish and clean everything before I fill it. but I am really pleased, as I have basically made everything apart from the barrel and trigger frame. |
