I have an aluminum pipe that I sent for milling. This pipe is the body of my semi-auto cartridge-fed hybrid and I milled it because I had to cut a hole for the spent-cartridge ejection port. After I received my milled pipe from the workshop, my cartridge no longer slides through it (it gets stuck so...

Have you tried at 1 bar? ):

Im not really sure what to do, I doubt I will get the power that I want from the size of cartridge Im planning on using. (around the .50 BMG size) So my thoughts have turned to a high mix hybrid. Using the shape of a firearm cartridge, could I use some kind of piston? EDIT: Modelling roughly the sa...

I didn't expect the friction seal to hold up to 200 psi. This gives me a lot of hope for my own friction seal. When will the long awaited video be up?!

we'll see this evening.

EDIT *** Opps, didn't see that.








EVENING IT SHALL BE (:

Wow the diameter is 1/4 inch? That's really small! And 200 psi is really sexy.

well the idea behind it is not to have to use cartirdges in the first place... But the thing is that I want to have a working self-loading cartridge system, not a semi/auto hybrid. The advantages of using hybrid cartridges over pneumatics (assuming a friction breech is used instead of a burst disk)...

I'm impressed by your ability to guess the calibre from such a shoddy photo.

It is, sir, exactly, 1/2 an inch.

Brilliant! Thanks for answering.

Here's a peek at what I'm working.

P.S. Some of the parts are still in the workshop, hopefully they will be machined soon by my ever-procrastinating friend.

Okay thanks for all the suggestions.

I wonder if the connector and hose from a shock pump could be bought separately, if not it would be quite a waste to buy a shock pump and dissect it just for that.

Has anyone injected MAPP through a Schrader valve? I searched the forums for a how-to but couldn't find one.

Maybe he has epoxied himself to the wall or something and has been stuck ever since.

Does anyone have a clue what JSR's up to or where he is? He's been missing for quite sometime already.

This is all very interesting and you're tempting me to build one. I did a quick google and found

http://www.fusor.net/

Is this where you got most of your information for building a fusor? Or are there other websites that are better?

Looks like Zeus went on a holiday... JSR, I'm working on something very similar to this design (I know you are working on an oxygen-version and I hope things are swell!) But I do have a question about this design, how do you intend to fuel your cartridge? Do you inject the mapp gas through the Schra...

Thanks Jack, that might actually work for my model.

P.S. I will have something decent in a month that will hopefully delight you. 8)
