Enjoy the awkward silence of me shooting my ball valve musket.

It didn't show up on the camera but the gauge reads 260 psi, a good pressure for glass marbles but not amazing for steel and lead.

Very nice!

CO2 might not be the best idea though... you need to join the cheap-o Chinese HPA pump club!

+15c outside today instead of - so I got in the workshop for some BFG modification work.

Well it seems to work nicely. :D

Other ideas I have planned are a shut off for the reload cylinder so it needs to be loaded manually not semi-auto :idea:
Why? because I can and I might not want to leave a BB loaded. :shock:

Removable magazine, mainly to make it easier to store and to check if it is loaded or not, no way at the moment as everything is covered.

Box in the magazine and change the hoses to all black, just for looks 8)

They can only do harm!

Ahem,

why do you think I should switch to a pump? My little tire inflator charges me up to 400 psi in half a second, a hand pump would be a bigger hassle I would think. Co2 is a bit more expensive but until I get my paintball tank remote line working it'll have to suffice.

A nice three stage pump will take you to 400 psi in very little time, and air being less dense and temperature sensitive than CO2 is going to give you better and more consistent performance.

On the note of cheapo Chinese HPA pumps, my adaptors arrived yesterday, so I'm no longer relying on an improvised Schrader adaptor and I can pressurise things with abandon.

My brother has been quite adamant, however, that I'm not allowed to pressurise his bike shocks with it. (Oh, the days when we thought that shock pumps were high pressure).
Does that thing kinda look like a big cat to you?

Rag, do you mean your brother doesn't want hot, moist air in his oiled "shock absorbers".

41C in a couple of days here, so I might have to open a window in the shed!

Summer already? I had to clear a foot of snow at -25 yesterday morning :shock:

Possibly, but I also suspect he doesn't want them pressurised to 4000 psi.

I didn't know that about HPA, thanks for the info.

I'm considering converting my ball valve musket to a coaxial valve but I have to work within the design of the mechanism. Do you guys think this coaxial piston would work?

This would allow me to use the flintlock hammer I have on the gun to act as the impact force that pushes the piston back.

Edit: Oops, I forgot to add that a spring would be behind the piston to close it.

Look up quick dump valves on the search, that's essentially what you describe.

I tried casting an endplug 2.5" diameter in thin walled plastic pipe... heat from curing slumped the thin pipe... may try to cast again in layers so it doesn't get so hot.

In 1/8 thick 1.125" od polycarbonate the casting went well, a little heat and it slid right out
