The SideStrafer

Unread postAuthor: noname » Wed Jul 18, 2007 2:15 pm

This thing is simply amazing. It empties itself in about 2 seconds (~250 rounds). The concept for this gun is totally new, as you may have seen from my sig. The body is square acrylic tubing (sweet!) and the vortex block is flat on it's side, below the gun. This is the second "full hole" vortex block I've made, because a partial hole wouldnh't work well for this gun. The bottom of the vortex hole is covered with aluminum sheet. The front is plugged with an acrylic cube. Another acrylic cube (thanks Modder) is the plunger, while another acrylic cube, with an O-ring on it, serves as the back plug. The O-ring doesn't completely seal the back, but the gun still shoots better than any other strafer I've ever made (keep in mind, that's 8 or 9). The blowgun is attached to the vortex block by a compression elbow, a tiny piece of 1/4" brakeline, and a drop of epoxy.
The BBs are blasted out of the block as fast as the plunger can push them in, which is, as you can imagine, extremely fast.
Now, feast your eyes!


Edit: Sorry for the crappy pics.

There's a 3/4" hole in the vortex hole and in the bottom of the body. These were lined up, then I glued the block on with silicone sealant. Seals perfectly.

A vortex block on its side?
Brilliant!

Now I'm off to try and make one :)
Where do you get your springs, by the way?
I think I have a couple that will work, but my hardware store doesn't have any of the low compression-weight ones like that.

This one is pretty strong, I'm going to try to find a weaker one. My Ace Hardware and OSH have like 50 square feet of 'em.

Oh, Fnord, don't expect to find the square tubing at a hardware store, just so you know.

I know, I figured you bought acrylic sheets and made the tubing yourself. When I finally get around to making one, I'll probably use round pipe. I'm not worried about construction problems with round pipe, just as lond as I understand the concept, I'll make it work.

Oh, and thanks for the spring idea Redneck.

There ya go guys! The stuff is cheap, and there's plastics stores all over.
Fnord, you're going to make it overly difficult for yourself.

Making things difficult for myself is what I do. If I complete a project without breaking at least 8 things and swearing less than 30 times, the project was too easy.

Thanks for the link though :)

I think projects are easy when they're just cutting and cementing, and then tapping a hole for a schrader. Projects like this one take lotls of measuring, drilling, sealaing different parts, shattering the damn acrylic, rebuilding, etc.
