1/2" Sabots

Unread postAuthor: PVC Arsenal 17 » Sun Jun 29, 2008 11:11 pm

I took a trip to Linens 'n Things the other day (don't ask me why...) and I came across these. They're little plastic tubes that you fill with water and freeze so you can get ice that fits in water bottles. They come in a case of 16 for under $4. Each tube has 2 blue snap on caps at each end. They're about 3.5" long.

With the caps on, the tubes fit very well inside 1" sch40 PVC. I've been trying to come up with ideas for what to do with them. So far all I thought of was to put a rolled up note inside and blast it over to a neighbor's house. The note would read "keep your f*cking kids off my lawn!" :lol:

But the best part is that with the caps off, the tubes themselves fit very tightly inside a 1/2" socket.

I'm brainstorming ideas right now for a simple, compact "shotgun" that would make use of these shells or sabots... whatever you want to call them. I was thinking that I could replace what would be a barrel with a 1/2" coupling and simply plug preloaded shells in and fire. They fit tightly enough that they shouldn't fly out during firing, and the length of the tube should accomodate a good number of airsoft bb's plus cotton wadding at each end.

It would easy to prepare the shells and even easier to load them. If I can come up with a launcher small enough, I might even share this on some of the airsoft forums I go on. They might like something like this.

$4 for 10?
IDK, I saw 175 yellow Ideal brand wire nuts for $10 in home depot. Those fit in 1/2" copper pipe and a different (than sch 40) size pvc.
I could mount field heads for arrows through the front and bolt them to a nut. Or epoxy the whole arrow shaft in.
Very professional for much cheaper than a lot of 1/2" ammo.

Maybe try a burst disc in the back.
I was thinking if you use those tubes as cartridges ,and cut a hole the cap, it could hold a burst disc maybe.
Then the shell will be powerful whatever valve is used. 8)

I don't plan on actually shooting the tubes. I plan on using them as shells for airsoft bb's. You would just plug them into a 1/2" outlet and shoot. They would be completely reusable.

Well the price isn't bad for that.
My one idea was similar only that you would cut/drill a hole in one end-cap so that a burst-disc (tape or foil) would be held in place. For a burst-disc (in the rear of the shell).
Wadding would still go in the back of the shell.
(like Davidvaini's BD EDIT:inverted though with no end-cap).

Your shells would still be re-usable.
Just an idea I had the other day similar.
(I'm building a breech-loader and had similar idea for burst-disc cartridge, in front of sprinkler valve).
That's all. 8)
