Way to read the tread...
This entire thread is about his amazing hammer valve that he made, and is implementing...

From the getting place...
Hammer valves are not exactly easy to buy, hence he made his own. Hence everyone makes their own. I think many paintball guns may use hammer valves, but they are designed for crazy pressures, and small volume.
Look around at every other post here related to hammer valves, and you will see that they really aren't that hard to make.

Steampunk fits like a glove.Bolt action and flintlock don't mix historically.


And I had that exact Back to the Future scope in the back of my mind hahaha. :D


I'll try to not overdo it...kay?

All ornaments are attached with either brass screws or brass nails.

Still need to do a lot of stuff, but I'm slowly getting there.

Hammer and trigger are functional now.Trigger has a counterspring, so it automatically locks the hammer.

Chamber and barrel are both sleeved in brass..

Oh lord, that is such a beauty!!!
I can almost see the zeppelins approaching over the horizon, and I think the man next to me is wearing a monocle...

All it needs is that giant scope and a big brass pressure gauge on the chamber.

Good work.

That is a magnificent rifle (can i call it a rifle yet?).

Your attention to detail is impressive, it looks almost nothing like a spud gun, and has already been stated, but more like a colonial weapon.

I'd ask for damage pics, but we don't need them, the gun is impressive enough without them.

You have quite a talent BTB

Looking great in the last pic BTB!!!

Take jeans diagram (pg.3) and use a co2 airsoft or bb pistol (dummy co2 cart, PB hose or other piping) where the hammer trigger and exhaust are shown.
Then a brass blowforward bolt added is what I've been obssesed with lately. :)

I love brass.
Got into it when I noticed the prices at second hand stores are sometimes lower than the scrap per pound rates.
I got one brass candlestick where the handle would make a perfect trigger gaurd, And a 1/2 inch brass nipple fit perfectly where the candle goes. Another candlestick with solid handle shaped base too.
I had some round brass ash trays with cool designs so started thinking of an all brass pepperbox burst disk design(high pressure).

I've put that on hold for now while designing a brass high pressure blow forward bolt. (finally solved the riddle how everything will fit yesterday!!!).

Brass fittings are awesome because there are male thread or female thread of same parts, reducer bushings OR couplings, interchangeable with galvanised mostly ,and nearly all high pressure.
(Except for some cast brass fittings and garden hose pieces).
But they're expensive so a lot of thought is needed or bit of $$$.

I spent about an hour in Home depot in "design mode" For example the male threaded brass "T" could double as the mag opening (for round shot)and front etc. etc....

I was stuck on the pin to block the loader tube, ( my design will have a piston larger than the back of the blow forward bolt and least restriction possible)...
I finally came up with using a reducer coupling or bushing and threading the smaller BFB casing INSIDE a larger pipe (internal side of coupling) so the blocker pin will be centered (grooves cut into back of BFB case and pin attached"-" to a "+" center. The piston seat could be larger than the BFB tube and between the external larger pipe filled with epoxy.
(To create the piston seat).

Hope any of that makes a little sense...I'm just excited about this design I finally think I solved. (hopefully a post soon) :D

BTW, Seems like you could use a few different parts and go higher than 600psi(?)

I hope to see yours soon! Good luck on it.Take your time, if you use wood, get a plane...and a chissel.They really help.

BTW, Seems like you could use a few different parts and go higher than 600psi(?)


With a heavier hammer I could go as far as 900 right now.Perhaps I could already..
I'm just not that sure the QEV will last that way.
Plus...600 psi is plenty as we have seen in other showcases.
I'll keep a safety factor.

Lacker is drying as we speak, Looks like it really brings out the wood.

THis weekend I'll reassemble the gun.I still need a triggerguard, a barrelsupport, and some general finishing touches.

For now I won't put a mag on.
It might ruin the look.I'll think about a removable one some more..

SO, FEEL LIKE WATCHING PAINT DRY??
