Re: Milkor MGL drum mechanism...

Dear god, it's gas-operated?! I would have never guessed that... The other disassembly video i watched didn't show the X-ray part, thanks a lot! It seems that there is a small spring loaded piston at the start of the barrel that uses the gasses of a shell being fired to disengage a ratchet mechanism...

Milkor MGL drum mechanism...

How on earth does this thing work? I have quite some knowledge of firearms in general, and cylinder fed guns with pre cut grooves such as the Pancor Jackhammer, Webley-Fosbery and even the Solar Eclipse launcher make a huge amount of sense to me. But this thing (and the lack of cut-away pictures) ju...

Re: Short question topic

Thanks! I knew these existed, but i would have never thought of using them in this clever way... Just ordered one hehe.

Re: Short question topic

Two non related questions here: I was recently successful in filling my cannon from a scuba tank using a paintball fill station adapter and some 6mm pliable copper line by just opening the main valve at a VERY SLOW pace (i only needed 50-60bars). But turns out, i only had like 70bars left in the tan...

Re: Using a pneumatic cylinder as a recoil buffer?

Oh certainly! Thats what i wanted to use the special x-frame aluminum profile for in the near future. But because this was just a test at less then 4 meters i just went for the most simple thing that i could shoot ;) The washers are supposedly the same diameter as the barrel (25mm), but in reality t...

Re: Using a pneumatic cylinder as a recoil buffer?

Ooh, i scored a non-sideways hit! This one was without using the particle board backstop.

Re: Using a pneumatic cylinder as a recoil buffer?

Did a few test shots at 40 bars on an old aircon radiator. rsz_img_0725.jpg rsz_img_0723.jpg The particle board i used as a backstop is about 38mm thick. I also took a shot at the board without the radiator and it went clean through even tho the projectile impacted sideways. The projectile is made o...

Re: Using a pneumatic cylinder as a recoil buffer?

Some progress:

The cylinder is not yet attached to either the cannon or the stock, and the stock itself still needs some reinforcement, but it's a nice indication of what i'm trying to make :)

Re: Using a pneumatic cylinder as a recoil buffer?

So if comparing it with car suspension, the hydraulic buffer would be the shock absorber and the pneumatic part would be the spring? In a crude way at least. Reading all of this makes my kinda think i overestimated the recoil that my cannon would create... But heck if the cylinder can make the canno...

Re: Using a pneumatic cylinder as a recoil buffer?

Wow that looks very similar to what i'm building actually. I would assume a hydraulic buffer would be a bit stiffer than a pneumatic one, but if it's too light i could always attach a shrader valve to one of the ports and give it a pump or two. But i need to be careful now not to build too much of t...

Re: Using a pneumatic cylinder as a recoil buffer?

Hmm i used the edit function to fix a typo in the title but it seems like it created a new thread somehow? Guess the other one can be deleted.

Using a pneumatic cylinder as a recoil buffer?

I've finally revived my old "anti tank" lookalike cannon idea. The cannon itself has been in firing condition for quite some time now, the main issues it had were leaks, a trigger mech, a reliable way to pressure her and some kind of "stock" that would allow me to shoulder fire her without too much ...

Re: Is spudding dead?

Same here... I live in a somewhat quiet rural village, 5 years ago you could pretty much fire a howitzer in your backyard here and not a soul would notice/care. But now so much of that agricultural land has been sold off and turned into industrial parks, it's just saddening how quickly those big ugl...
