when using the propane torch, set it to low and sweep over the crack as if you were spray painting for a total of about 5 seconds, then heat the rod and push it through.

Why dont you take a look at technician"s QDV. The chamber is coaxial around the barrel.

Get a fridge or an AC compressor. Trying to compress liquid propane will break your compressor because it will expand into a gas in it's chamber and freeze the rubber seals and cause damage. If you want high pressure gas as a liquid get a CO2 tank.

JSR is right. Like me, you'll probably accidentally come across some fitting that does exactly what you want. That o-ring certainly won't.

I think It is just a little fat... Look at a proper dart... It's length should be many times its width, and it should have something to stabilize it... You could try simply getting those three big nails, make fins on the back, and use a wadding in the chamber, even tissue paper would work, fire 3 at...

If you want to have it seal and never have a chance to leak, just use heat to form a new bond in the actual material.

Take a propane torch to it, melt in some polyethylene over the crack. it will be quick and easy. gluing is going to get tricky and messy.

forget epoxy if it is polyethylene. In fact forget any normal adhesives if it is polyethylene. You need to use a heat bonding method. http://www.ehow.com/how_5819102_repair-polyethylene-kayak.html If you cant find a polyethylene welding rod, I guess you could heat-bond ice cream container material o...

If the site became of interest to police then, sure, they could track your ip adress. And if they have your IP adress then they know your internet service provider. From here it gets annoying for them because they would have to get all kinds of legal permits to force your ISP to reveal your identity...

Buy a floor bike pump and a screw in schrader valve. That would be your best bet IMO because you would save a lot of time on making the pump, And you would be guaranteed to be able to get at least 200PSI with a normal floor pump. For less bulky air lines you could try paintball macroline. It's what ...

POLAND_SPUD are you saying there is a fitting available that acts like a pressure regulator? Reduces pressure downstream? How?

Welcome to the forum; got a particular launcher in mind?

I got a nice smell of chlorine gas from the positive terminal. :angel10: :angel10: :angel10: :angel10: :angel10: :angel10: :angel10: :angel7: :angel7: :angel7: :angel7: :angel7: :angel7: I get the feeling that when you finally land on a cartridge you're happy with, it's going to be adopted by NATO ...

$100 is about the most I'd spend on this... Trying to find one as small as possible and without gauges, so it will fit in my design... You've put me onto a good thing with those nitrogen regs... But it looks like they wouldn't fit. I wonder if I could cut the gauges out and plug the holes? hmmm... P...

Hello all, I'm currently contemplating trying to make a pressure regulator myself for my bb cannon. The reason is that my tank can hold 400PSI but I don't want to expose my pressure washer handle to that high a pressure for a very long time, and also, Since it is a valveless design, As the tank empt...

I've been lusting over one of those for a while... When I get one I'm going to find its max pressure...

PS how did you get it so cheap? Can't find it for less than $145 AUD
