I think he meant no conventional hybrids or anything else conventional for that matter.


You know me too well.

I dislike burstdiscs, having to replace it every shot.
A piston hybrid has more appeal to me.

But if I'd have to make an ignitionsystem...I don't know...
It feels like re-inventing the BP gun but a lot more complex...just to stay within SF rules...

A waste of my time..

I really only like pneumatics...this is just an extra

I know what you mean, imagine how easy this hybrid cartridge lark would have been if I had been using solid propellants!

well...I got the basic idea done.
The exact location and angle of both the dieselpump and catch will be determined during the build.In the schematic, the dieselpump is not even close to being in the right location.It will be at the very start of the stroke.

I want to tuck them in as much as possible.So I might put them lower or higher up on the sides.

the barrel/pistonhousing assembly breaks open and an arm connected to the stock drives the piston to the catch.

The barrel is prevented from breaking open by a bolt type lock that also minimises dead space.

I'll try and figure out if I can " automate" the cocking of the hammer and the dieselpump by synchronising them with the breakbarrel action.
If I feel up to it I might add a mag in this cycle.

The catch is released by a rod, wich gets struck ( indirectly) by the hammer. I'll make the rod float as a safety.

Depending on the force needed to cock it I might leave out the shoulderstock.
Anyway...here's the basic scheme:
( lot of work and lots of welding!! :D )

A hammer valved spring piston, everything but everything I've heard about the Dutch is true!

Looks good, but really since you're releasing a catch, why a hammer as opposed to a lever?

The hammer and floating rod together will form the safety.
My idea is it won't work without cocking the hammer..


but..
You are right...it's not really neccesary..
Hmm..I'm just a sucker for hammers I guess...


It might save me some work to leave it out...and it might look cleaner without...but ...a hammer is still pretty darn cool...
