Mark - you may want to do a little more research as to what composition they were using

You can find what they have published as far as the much circulated defense paper mentions, but chances are that is not what they settled on.

[mark.f]

Yes, I guess it is a paper from 2006 I'm going off of, but it's a good starting point.

[Crna Legija]

Oh I thought the Wiki page said about 20% more. Whatever

lol you must have read the 21% in air.

I stuck a schrader in the fill port and that worked fine so I may just use my fridge compressor and put this thing up to about 400 or 500 psi if my fridgy can handle it.

yeah that's find but id give it a good coat of anit rust paint on the inside because it will slowly fill with water.

[Gun Freak]

Aren't the cylinders aluminum? The won't rust. And if it fills with water, I'll take out the fill, and tip it over and let some water run out of that port. Obviously it won't all come out but it'll be good enough.

They can be a multitude of materials. How much does it weigh?

If you're modifying it for low pressure (500) PSI fills, I would drill and tap a spot for a draincock at the bottom or on the side.

Just like paint ball cylinders thay can be made from lots of different materials if yours is old its probably steel.

[Gun Freak]

It's pretty heavy, at least 20 pounds. I wouldn't be comfortable drilling into it...

The shot shot is very cool What was that fired out of ?

[jackssmirkingrevenge]

Smallbore hybrid at 17x, 4 x 3mm steel BBs.

Very neat entry holes on the first sheet (0.6mm steel), bounced off the second sheet but there were two interesting "extra" marks which probably came from the "slugs" knocked out of first one.

Just saw the video, very impressive. Really makes me feel like to build a hybrid rifle

Very nice, although I think it should be mandatory for everyone to colour correct their high-speed footage (and normal video footage as well, come to think of it); unless they're stuck using something like WMM (although you can download third-party colour correctors for free).

The example below may not seem that important to some, but that was shot in perfect conditions outside and I didn't have too much problem with background contrast (i.e. shooting a greenish object with a greenish background) and the video lacked anything that would look significantly better with some colour emphasizing; such as a muzzle flame, bright projectile or a watermelon target. Your video sort of lacked anything worth emphasizing as well but I still think colour correcting makes the footage a lot better.

Edit: Oh and you can see the edited footage lost a little detail but this could be brought back with some contrast. I only changed the colour levels (RGB), saturation and gamma.

Well you know, some of us are just having a bit of fun with our youtube videos, and not really wanting to turn it into a commercial venture

Seriously though, the Exilim has its limits and I think this is operating within them.

I'd still consider myself as one of those 'having a bit of fun' people as I don't really invest much time in to the videos; although im up to $50USD already

Indeed and that's why I think colour correction is so good. It has often change my mind about high speed footage I have filmed when viewing it on the computer; I've been disappointed with the footage until I've added colour correction. It's not only an improvement of 'aesthetics' either, as I said before it can be used to contrast between foreground and background or target and projectile or increase the lighting if it was filmed under bad light.

I think the two main, and possibly only, reasons for why we have the Exilim is for the aesthetics of seeing something in slow motion and for understanding something occurring at a speed where it is easier to see what's going on.

With the footage you posted, you can't really see much of what's going on because the projectiles are just going to fast but perhaps you can see more with a bit of FX fiddling.

I'll be happy to mail you some originals if you'd like to prove a point

Some more hybrid shotgun fun in the meantime:

... and more, haha!
