Growing obsession with 12v compressors

[Mitchza89]

I've been seriously interested in these little beauties for a long time. I'm not overly sure how they work in comparrison to a regular compressor, but is there any way I can add a crank handle to one?

[Cosmic Muffin]

they work the same as a normal one but without the tank.
you would have to be putting on a really small crank handle
how big is this one you have?

[Mitchza89]

Well having a rather large crank handle on it, would give me alot of leverage making it easy to get to high pressures

[Cosmic Muffin]

i think i know what you mean now
yes you could do that, take the motor out, weld a bracket to the compressor, then stick your handle in.
should work

[Mitchza89]

I just found an old one in my old man's shed! I just tested it and it doesn't work (the motor just probably blew) but, it will work perfectly for what I wanna do with it!

It should be a hell of easier to get going then making a high pressure stirrip pump from scratch.

[Cosmic Muffin]

yer, use what you already have without blowing your money
it will take you ages to pump guns up tho, cos the compressor piston chamber would be about the size of a dice

[Mitchza89]

That works fine for me, I mainly use 6/8mm bore piston guns. I have an ultra quick pilot so my guns are efficient enough to have really small chamber volumes. Now to make this little beauty

Thanks alot for ya help Cosmic

[Cosmic Muffin]

yer i recon its better to make smaller bore guns too, 6mm is what i do
no probs mate
happy to help a fellow Aussie

[Mitchza89]

Wow I'm stoked at how well this working....I've just welded on the handle and it rules! It works! except I think I'm going to add a gear to make it easier to turn at 300+ psi

[Cosmic Muffin]

g you don't mess about, already into production
have fun finding a gear, i hate trying to find stuff like that cos usually they aren't sold at your local bunnings
good you got it working 8)

GET A PIC UP OF IT
i wanna get a look at this little bundle of joy

[Mitchza89]

Well every battery I have is flat so I'll get some on my way back from work tonight. Man I am so gonna mount this on a gun! *crank crank crank BANG*

[jackssmirkingrevenge]

Interesting concept

It's a tiny piston that needs to rev high so I would suggest a massive handle attached to a small gear, so every turn of the handle gives you more piston strokes than a turn of the motor would have.

[Mitchza89]

Yeah that's it. This little pump is perfectly suited to my 6mm. I wonder how much pressure I could get out of it...

Tomorrow me thinks I'll have to do some serious testing with this little pot of gold

[Cosmic Muffin]

is the 6mm the one with the square QEV?
i was having a gander at that a few minutes ago

[Mitchza89]

Haha nah I'm still yet to get the QEV. For now i'll just use my good ol' piston valve
