I think that if I boost my fridge pump with my shop compressor it will put out 60.
By the way, dont you think that my "most dangerous thing you have ever seen before your last creation" deserves a machined piston valve?
We should indeed. But where?

It should get one in time for sure!
I'm in the middle of nowhere...Just around the corner from Nothingville...
The question is: when?
I need a regulator, as I destroyed a couple, trying to turn them into an airflow interupting device in the quest for pressure actuated full auto, and am now without.
So we need a portable airsource.And 12 grams are too expensive.
( 12 gram adapter with a QD on the otherside = portable pressure source)
I've just attempted to paint some real looking flames in bright orange on the tip of the barrel of Mr.Porter, but I'm no Mike Lavallee....
I'm hoping it will look okay tomorrow, when the paint is dry.Otherwise it's back to black.

How much watt does a fridgy draw?
We could drain power from the car using one of those DC->AC adapter thingies, but over like 400watt they become rather expensive. And fridgies draw more power then that.
Or we should try to hook up a compressor directly to the engine of a car
Now that I think of it, what a about converting a combustion chainsaw into a compressor?

you cant just input air to a fridge pump its not quite that simple.
you need to let the pump run till it reaches max pressure then up the input psi a little at a time. like say you reach 800 then you input air weight till it stops climbing, Then up the input pressure in stages if you dump 60psi into it at once it will stall the pump.

The compressor you are talking about, is its case under in or out-put pressure?
I could imagine that when the case is under input pressure there is no problem.

most (i would say all but to be safe) fridge compressors the case it under in put pressure not output pressure the output is conected from the pump to the case buy a thin copper pipe with a iner bore of about 1mm
