This is my fith post in a month...Guess I just got a little Post Happy.

Anyway, I posted about a new valve about a week ago and I said I would try it out. So I did. The valve I was talking about <compressor nail gun repacement valve> is installed and it works better than any other valve i've ever used. Back to the gun. The barrel is 1/2 inch cpvc nested in 3/4 inch cpvc. It has a clip system making it a simi. The tank is 3/4 in pvc and can hold 120psi. I plan to wrap it in copper wire to bring the top psi to 260. Everything is connected with pressure rsistant tubing, the orange stuff you find in the hardware store.

Pic's comming soon.

The valve sounds like its really cool, but I'm not so sure about the airtank. I suggest using PVC tubing for the entire air tank seeing as it has all the fittings and glue you will need. I'm wondering why your 3"4 inch PVC is only rated to 120 psi. My SCH 40 half inch PVC is good to 600 psi and my one inch SCH 40 PVC is good up to 450 psi.

Also, I'm not familiar with the process of wrapping pvc in copper and how it will raise the PSI tolerance, so it would be great if you could explain that.

[buckbogey]

ValveWire cant stretch much right? So when you wrap the entire tank with copper coils, the tank cant expand and fracture. For more on the valve, here is the post: up top, sry.

I tested.

40psi can send a dart a whopping 63 feet <mean of 10> 120 <the point at wich at the tank starts to expand> It could sent a micro 108 <mean of 10>

Pics still coming

Is the "orange tubing" in your tank expanding or are you using a type of flexible PVC that is expanding? Sorry for being so confused, but I'm not clear on what part of your tank is expanding.
Also, that's some nice range you're managing to get but I'd be worried about wrecking the dart at 120 psi.

[buckbogey]

The pvc TANK expands at 120 psi. The tubing can take 365 psi before it starts to expand. The tank expands increasing the diamiter by 1/5000 of an inch, not much but at 3/5000 the tank explodes.

About wrecking the darts. 120 doesnt hurt them at all, because th tank is so small, there is no fishtailng either.

Pic's comming soon!

I was testing out my gun and some darts that I made. I was thinking about how the 2" darts I use don't load easy and fishtail a lot. So I came up with a dart that is 1/2" long.

It works great. It increased the top range of the gun by 12'. And it was a lot more accurate.

Heres how to make it.

Cut a piece of fbr that is 1/2 inch long. take a sharp pencil and poke a whole in either end so they meet in the middle. Dont carve out the middle, just puncture it. Take a couple of 1/4 inch long screws and wedge them in either end. Take some hot glue and put a HUGE glob on top of each screw so it seals it in. The bigger the glob the better, but make sure they won't touch the barrel.

Shove it down the barrel and fire. The firs time I shot one it exploded upon impact! I made a few more stronger ones and bam, those things HURT. I hit in the middle of a 1' target from 30' 9 out of 10 times. They eliminate fishtailing, because they are so short, and they wont go cartwheeling, because they still have some lenght to them.

They make loading quicker because it doesnt matter which way you put them in.

Tell me what you think.

I don't even know where to start here... Everything you've written sounds like bullshit.

3/4" SCH 40 PVC is good for 480 psi. 3/4" SCH 80 PVC is good for 690 psi.

How did you measure the tank expanding 1/5000"?

How do you know it will explode at 3/5000"?

You can't increase the pressure rating of your tank by wrapping it in wire. Attempting to do so would fall under the category of `evolution in action'.

Exactly what I felt

[buckbogey]

I promise you it is all genuine. The pvc can withstand what it is rated for, but it expands some before ith gets there.

Try this: Make a tank and take some wire ad wrap it arround it about 20 times. Mark the exact start and finnish places of the wire. Take the wire off and pump to 200psi. Re-wrap and I bet that the wire doesn't make it as far.

For anyone who reads this: Do not judge me by my Join Date. I have been with NH for a while, but my old account got screwed and I couldnt use it anymore, so I created this one. I have been with Nerfing for years, I have been here for the fall of NO, the rise of this site, and 2 downings of NHQ.

I got all my info after working in my engineering lab for a day. I was doing a test for a pipe company <i cant say who for security> and these were my results.

Why the heck am I getting flamed at for sharing my new eat shit!!!!!!!!!!

Because you're trying to convince us that your credentials are beyond reproach yet you sound like you have no clue.

If you had an account here or on NO and actually used it to benefit the NIC, by all means share who you were. If you're unwilling to do that then don't expect any cred for vague suggestions of having been around. Frankly, time doesn't mean shit anyhow. There are people who've been in the NIC for years and still have yet to contribute anything worthwhile.

On the other hand, there are people who come and get respect with their first few posts. They don't try to convince anybody that they're cool, they just are. Sometimes you can't fake it.

Your wire wrap measurement is seriously ghetto and unreliable. 1/5000"?! Even micrometers don't have that kind of precision unless you're measuring in the sub-inch range.

You write like a 10-year-old. Nobody would hire you to do engineering. Go to school.

[buckbogey]

If I'm getting flamed for sharing my knowledge, then why the heck do I do it?

And yes, there are insruments that can measure up to 1/1000000000 of an inch.

I know what you think, but heck, if you dont want to believe me, then for gods sake, dont.

Dont reply expecting to get an anwser from me, i'm not comming back to this topic.
