After several layout changes I'm going to try this setup, the chamber is split to give me room to get the barrel straight into the valve :idea:

Sounds like a plan, will you be making a wooden stock?

I've always been partial to the "W2000 custom rifle" look from Hitman 2

No, there is no stock really, all the workings will be at the back bullpup style

Had to come up with a new pneumatic circuit as it uses a double acting cylinder rather than a spring return like BFG. This seems to work, adding a EOS (end of stroke) sensor to the control valve seems to give me what I want.

If your inspiration is the WA2000, there's plenty of wood on it:

Will you be replicating it?

POLAND_SPUD would shed a tear of joy to see that :D

Your dedication to this painstaking form of construction is very admirable.

No jig saw available? Hacksaw blade? Working with what you got??? Sometimes I still have to wrap a blade with a rag and saw like crazy to get a job done...

Drilling holes and filing is my therapy.

10mm thick alluminum and tight corners not so jigsaw friendly, took me an hour to get that far :| Did a bit more today, made trigger and started to mount trigger valve.

Sort of got most of it worked out in my head, but anything can change, and usually does :idea: :idea:

Should look somewhat like this, still not 100% sure where the pilot valve is going, it's hiding behind the main 1/2" valve in the picture, the barrel will have a removable 300 mm extension.

Workshop is 50 feet away from the house, so it does :D no heating though so I don't do any work in the winter much :cry:

Control valve pretending to fit on RH side

How I make a split clamp for 1" PVC, about 33.5mm. Barrel goes through the 10mm hole and rail attaches to the top.

Drilled 2x 4.5mm (anything smaller tends to wander) down just beyond eventual cut line (split in clamp)
20170912_143341.jpg
Drilled down 3.3mm into 10mm barrel hole, then drilled down 4.2mm halfway so I tap M4 in the bottom of the hole then M5 in the top half
20170912_143433.jpg
Drilled 33mm hole with hole saw then polished out until PVC fit
20170913_123700.jpg
Cut in half, then used previous 4.5mm holes as starting point for 3.3mm holes, tapped M4. Cut off the top corners and polished a bit (this is old scrap material)

Finished
