I'm waiting for an adapter for my coax I'm working on.

I need to solder the last parts of my marble sniper project and the make a piston for it.

then I think I will modify my first pneumatic because I almost don't use it anymore.

after that i get him to dig up some pipes for a 200bar piston cannon.

Yikes!!

You must not have had a spudding mishap if you are that confident!

You be carefull with that okay?!?
The risk goes up along with the pressure!

yes but not if you have proper pipes and fittings (aswell as machined piston) it is going to run on argon.

mabe some helium shots also

- Getting my burst disk noise cannons finished, mounted and ready for summer. I've been too busy with IT stuff here lately.

- An "exihibition" clear chamber/barrel combustion gun....for show and respectable performance...nothing record breaking however.

- Optimized, high performance, big bore, mounted 1x combustion with all the bells and whistles....goal is 2/3 supersonic GB.

- Toying around with some hybrid ideas, 4x or lower. Goal would be a supersonic + GB with as short a barrel and low "x" as possible.

starman your GB gun should have a problem to get supersonic without 3m of barrel at 4x or lower.

I'm goin' to OSH to get me a sprinkler valve.

Cool I like that other people on this site like water rockets. what is the largest rocket you have made? I made a 6 litre but that crashed now I made a rocket with three 710ml pop bottles that is waiting for testing.

I've been going on numbers I'm getting from HGDT. Here's an example with a 6' barrel and 3x mix...



...all with an entry level but optimized hybrid configuration.

I realize these are calculated but I've found HGDT to be pretty close on other smaller guns. I would like to give it a try sometime.

@ sticky tape, how did you make the launcher for your rockets, what is the release mechanism?

Today I am up to a new project (put the qev one on hold). I found an old co2 tank, (9 oz) that's threads fit perfectly on a 1/2-3/8 in adapter, so I am currently working on a hammervalve gun using the check valve on top of the co2 canister. It's going to be mounted on a wooden stock. I'm hittin up the flea market tommorow to see if I can find some cheap bolts fittings valves etc.

I used a quick connect coupling launcher with a varryation from the link that I gave you.

My launcher has a different stand.

HGDT give me 1000fps more on my hybrid than the chrony did soo.

Hi,

Current projects:

- Finish and present my DFTV golf ball accelerator

- Prototype my old idea, the Jet Gun, and see if I can get it to ignite

- At the same time, I have a scaled down experimental semi automatic in the works

- Finish my stirrup pump (should be able to do most of that tonight, really)

- And take my colleague shooting. Nobody knows about potato shooting here, so I guess it will get him pretty much staring in disbelief...

Regards
Soren

Why do you think that is? Sounds way out of whack there....like by up to a 100% or more....

Eh, I've been overwhelmed at work so I have been working extra hours. That, and I had a wake and funeral to attend this weekend which would have been my only free time to work on CF.

I've been toying around with giving CF a 20' 3" barrel instead of a 10' 4" barrel. Wine bottles fit quite nicely

I'm thinking on how or what I'm going to give up on monthly so I can get cable in my house for high speed internet hook up! Guess I better find out what it's gonna cost first, eh....

I'm trying to get my suitcases packed on time, might be a few days before I get access to a PC again so until then, take care fellow penetration enthusiasts, I'll be sure aim for a lot of that in Spain
