Would this work? Or do I need an extra 2-4 inches past the gas port.
Comments, picture edits or similar obsession of making ancient funs uglier and useless.
Just make it use a clockwork spring.
It works well with black powder, unlike a gas system design.
right so since I'm lazy and retarded I'll assume the cylinder gap closes on this revolver
so when it fires, the gas from the ignition should be enough to push that piston at the top back that transfers the energy to cock the hammer all the way back, under the lazy and retarded clause I'll also just assume that cocking the hammer also rotates the cylinder but the hammer has to make it all the way back before firing.
I dunno but I have a strange feeling this wouldn't work.
Don't have a picture but they also made a carbine version that was select fire and possibly held more than 6 shots.
dont be obsessed with a terrible idea anon, there is already semi automatic pistols that do this, for the same price and no effort.
it wouldnt be automatic
it wouldnt be worth it
The hammer spring would have to be modified as the hammer would have the extra mass of the gas piston and rods/linkage. Of course the arming of the hammer also rotates the cylinder as with all revolvers.
I'm obsessed with many things sometimes with several all at once...sometimes enough in fact i'll actually make them myself. (110 bar HPA bolt action 20mm shotgun, ball mill, 800lb capacity hand truck etc. diy projects.)
Actual firearms are beyond me legislatively and tooling wise, as I no longer have access to machining equipment.
I know there's a guy out there who's done exactly this. I saw pictures too, he made a gas operated SAA.
Of course now I can't find it, but I did find something similar:
Legal schmegal! Don't tell no one bub! Don't be a snitchy bitch.
No Anon, it would not be full auto.
I guess it would, i don't know how much gas is lost from the cylinder gap and if it would have enough but i can only assume it could.
You could make it aim Colt SAA Style with the sights on the top of the first arm and they line up when the hammer is back. But your sight height over bore would be ludicrous.
4/10 anon, there was an attempt
I don't get it. what's the point? this wouldn't make it full auto. it would still require you to pull the trigger every time, accomplishing literally nothing. except I guess it would be a nice SA trigger every time instead of DA?
I assume he means that if the trigger is held down, the gas will have enough power to rotate the cylinder and push back the hammer, which would automatically release due to the depressed trigger.
why not actually do research before posting? yes, fanning is bad for a gun. it's a great way to fuck up timing. You can modify a gun to be better for it if you so desire.
Sean Connery for size. This is an automatic revolver.
Jim March did this with his FrankenRuger experiment. The last time I saw an update it used a gas tube to cycle the cylinder, recock the hammer and eject the fired case. Once he had the ejection system working he fitted a magazine to reload the empty chambers as the cylinder indexed past.
Not true of the old Colt actions upon many SAA clones, including the Blackhawk, are based. These did not have rebounding hammers, so pulling back the hammer with the trigger held will index the cylinder to the next chamber.
Hells yeah, first thing I thought of when I saw OP's post.
Here's the vidya:
He also gives NRA funded talks to schoolkids in CA, so he's doubling down on God's work.
Forgot to answer OP's question. In most countries where full auto is controlled it specifically includes "any mechanism that produces automatic firing".
That's the one! I remembered the details incorrectly, it's not self-cocking but it is self-loading and self-ejecting by means of a gas system. End result is a nifty 14-shot 9mm revolver. Not practical but a darned neat bit of engineering.
He stated his cylinder was a custom deal from Bowen. I found his discussion of the project if you're interested in the specifics -
Even if the cylinder gap didn't take too much has out for the thing work, pushing the hammer back doesn't rotate the cylinder. You'd still have to pull the trigger to bring another round around. Might as well get a double action dude...
I'll try to find some....the main piston valve is pretty worn out. Something to do with the enormous acceleration forces it was subjected to when firing. I never got it to work as smoothly as I intended originally as the machine shop i did most of the parts closed down and i didn't want to spend the money to outsource the modifications. It ended up being a mule for my experimentations with different storage volumes, pressures and different valving. So its quite ugly.
Their rifle was a bit different (unless they also built carbines off the pistols, which they may have). But yes, similar mechanism and essentially Ye Olde Full Auto.
