Balanced Spool Valve

[Forum Admin]

I accidentally worked a way to load round ammo as well.  Because I cut the slot on the bottom of the valve for the trigger mechanism, the gun has to be upside down to load. lol I'm getting ready to head to Lowe's for parts, I've got a design that I think will finish the loading/trigger system.

I got the bolt action finished up, have to still finish the trigger. Here's the video of the progress: http://www.youtube.com/watch?v=FosguC1LlI8

I can't believe I didn't see that last video before. You could really borrow my sear/trigger design for this. Its not complete yet but I'm working as fast as I can.

I might be able to put some pictures of it tommorow... that is if you didn't already make the mechanism... its been 7 days

I'm using a zipgun type trigger mechanism, here's a post on it: http://airgununiverse.net/blog/blog5.php/2011/01/23/pics-of-random-stuff-i-m-working-on. I've restarted construction, to correct the mistakes I made on the first.

Nice photos.

Suggestion:  Do not solder the 3/4>1/2 fitting reducer at the barrel end.

Use it to slip your barrel in and out of the T as a breech loader.

I secure my barrel with a hook lock to keep from flying out.

Ahh... I was trying to use a zip gun mechanism as well but it was too hard to attach any kind of trigger and the charging handle. Thats why I went to a simple sear/trigger mechanism. Its a little bit harder to do but the rewards are worth it... especially when you can reload and fill it up as fast as you have demonstrated in the video.
