Ragnarok is right, a heavier BB would help. I suggest a .20g or .25g BB (I think .25g is the highest they go but you'd have to order it online most likely).

It's amazing the BB didn't go all the way through with a crater like that. I might put a pic up when I finish my project. Should only be a day or two now...

Ok, I changed the dwell volume to 100ms and it gives the same error.

I'm trying to use GGDT to optimize the chamber volume to a fixed barrel length of 12" but every time I hit optimize it gives me an error that says "Run time error '11': Division by zero." I tried the fixed chamber and fixed length options and those both work fine but the fixed barrel option doesn't....

Thanks for the info, jsr. That's good to know

Thanks far_cry. I'll have to check the vid out on a computer that doesn't have my ice age internet.

Ha no I've never been to EAA but I went to Country USA this year. That's pretty cool that you're a part of that though.

I go to Oshkosh maybe once a month its only 15-20 miles from my house

Or at 900 psi by the looks of it. Genius design, will definitely have to try this. This is basically a piston valve, isn't it? I can hook the poppet nut side directly to the barrel and the bottom of the tee to a chamber, right?

I need help finding a pilot valve that can handle a high pressure (300+ psi preferably) for a safer version of my recently built mini. I'm having second thoughts about the blowgun (like in my avatar) being able to handle pressure of 400 psi. I'd like to stay away from ball valves for such a small gu...

Yeah it gets pretty ridiculous what kinds of things our school computers block. ESPN fantasy football among other things.

Today at school I tried getting onto the spudfiles site but found that it had been blocked by our school's filtering system and had been put into the category of "Weapons." This disturbed me so I decided to use the re-evaluation function of the filtering system where I could send them a reason why t...

Ha so that's what that is. I've seen it mentioned here before but never bothered to look it up. Thanks a lot

POLAND_SPUD, I'll see if i can find something along those lines for a chamber.

jsr, brake line is very easy to customize lengths. Sometime in the future I might do some tests similar to Burnt Latke's to figure out the optimal c:b ratio for airsoft BBs.
