Hey. Im starting my next homemade (third one I think) and want to make a good semi auto gun. I was wondering what the best way to accomplish this is. Does the Zero valve work very well? And what else is out there?

The zero semi-auto valve should work, it's on his site.

Just a thought, has anyone had good results with Zero's valves? I heard that they realease air too slowly.

I made a Zero valve once but it had a leak because of the brass and o-ring sizes i used. Don't worry though, if you use the sizes zero tells you to, it will work. To answer your question, the air from a zero valve is released very quickly.

Zero valves areonly like $2 and they release air pretty fast. Hose handle valve is the way to go I hear.

That would release all the air at once...

Unless you use two, and regulate.

Compared to say a AT2k valve, a zero valve releases air slowly but is easy to make.

An idea I was planning on using in my next homemade is a sort of air tank that works the same ways as Zero's semi-automatic valve. Instead of the auxillary air tank being in the firing valve, you can use Zero's basic valve and attach the auxilary chamber in the air tank, itself, by means of a ball valve. That way you can fill up the smaller tank by opening then closing the ball valve. I have no idea if it will work, but I am going to try it sometime in the future.

Wait, whats this about hose handles releasing all the air at once?

Arn't we just talking about the simple trigger guns that attach to the end of your hose? In that case, shouldn't releasing all the air be impossible, as all you have to do is take your finger off the trigger?

Meh. I'm always wrong. :unsure:

Zero valves work fine, try adapting a Vintage valve...

Over on NHQ, I posted plans to make a semi-auto P90. It was a large airtank with two hose nozzles to regulate the shots. I finished it, using a cheap hose nozzle for the regulation, and a nicer front trigger nozzle for the trigger.

It sucked. The reason? Due to its design, the trigger nozzle released it's air extremely slowly. I only got about 60 feet with the thing....angled.

Point of this post? Not all hose nozzles release air fast. That is why I am on an endeavor to make a high-flow valve for cheap. You can find the prototype here:
Zero Valve Adaption

So far, it has worked like a charm, but you need a strong seal between the gasket and washer. That means using a spring that is tough enough to make that seal, but loose enough to pull back without too much difficulty.

Just by looking at the design yo ucan tell vintage works very well. I actually got around to building one and it releases air as fast as my sm5000 valve, though it doesn't close as fast. A truly brilliant design by vintage. Be aware, you have to experiment with it a little.
