So far..


And thanks for the comments!

Looking good (so far). You using Blender?

3d studio max. ;)

I want a frickled faced kid with a spud cannon chasing a potato with a worried look on his face across the yard. He should be reaching down grabbing for the potato all most getting him. The ...

So far..


And thanks for the comments!

I'd like to make a thread here to show off my 3d modeling!

I hope you like it! And I'm taking requests :3

Probably tommorow, When I've finished the flyback circuit.

Or that.

I even have one lying around.

*edit* problem solved 8)

Nope, I moved it backwards a bit.

I have a bit of a problem though.

The valve on the back.. when you disengage the blowgun from it.. it loses 3 bars of pressure. Haha.

going to get an old fashioned tire valve tommorow then I guess.

installed a spark plug and a pressure gauge

Tonight at 2 am people put the clock one hour forwards.

I'd send them to my place.. free of cost.

Does the time matter? I'd prefer to do it at 2 am.

Picture of it right now.

your pipe is almost never what you have to worry about pressure wise. The fittings are always much weaker than the pipe. For example, threaded unions at the 2" size can generally only take around 200psi, while their corresponding pipe can take well into the thousands.

I machined the fittings from ...

1" copper pipe with walls about 1mm thick is rated for ~1 000 psi. This will be able to take higher mixes than a conventional air compressor will be able to fuel it to. I'm assuming you're machining it out of bar stock?

No, it's piping, but i did machine the fittings. :)

I'll have to install the ...

I'm building a hybrid that's 35 mm in diameter with 5 mm thick walls, The thing is aluminium, what will be the highest mix I could use safely?

Thanks for the replies!

Jimmy: I might try that piezo thing you posted a link about. :)

The gauge doesn't need to be that fast, it's for metering fuel in a hybrid. :)

*Edit* the link to the radio shack site does not work, do you mean a piezo buzzer maybe?
