How the hell do you spend $1200 on a hybrid? I can see spending $30 on a cheap combustion, but that is a lot of money on a hybrid. Did you build the thing out of platinum laced with diamonds or something?

5.5" pipe, pressure testing, machined parts (well that was the cheap end) all parts galvanized and money spend on getting it the best way i can.
big propane tank. hydrauc fittings, 2" union and all that stuff.

also take this: i live in Norway and it is sooooo expensive for parts here.
BTW a 2" thickwalled steel pipe 15feet long

1200$... wow stuff is really expensive in norway...

[SpudFarm]

and even more expensive when you live at the country side

[POLAND_SPUD]

seriously I knew that large galvanized fittings may be expensive sometimes, but not that expensive, How much did you pay for fittings ? do you still remember ?

[SpudFarm]

i have not payed yet.
the chamber and machined fittings is at Larda now.

i just tell that the chamber and caps is going to cost a maximum of $340 not to bad but it is the barrel i have to pay a shit load for.

How the hell do you spend $1200 on a hybrid?

Heck, the Pipe Dream will probably cost on the order of $25,000 and I'm using a lot of scavenged materials. If I started from stratch I've no doubt it would be over $100,000.

It's easy to spend money if you're at all interested in scale, precision, and safety margins.

d_hall i try the best i can on all of those areas.
the tricky part for me is getting big enough pipe with the right rating.

how hig mixes will the pipe dream consume?

good job on the gun.
$1200 The most I have ever paid for a gun is $70

At most you could have your finger half taken off, or a artery cut open.

At most? I kinda like my arteries the way they are.

how hig mixes will the pipe dream consume?

It's being nominally designed around a simple 2X. However, one never gets full theoretical pressure so I'll be adjusting the mix until I get about 205 psi, *measured*... If that's 2X or 2.5X or 3X... so be it.
