That is not what the inards of a supah look like at all... The similarities stop at the 'T config' of the valve. A supah is chamber sealing, while the diagram is barrel sealing. A supah uses o-rings and a piston, while the digaram uses a diaphram. There was actual pictures at one point in time. Although I dont feel like going and fetching the link for such photos.

DAMN! I cant believe i got it wrong... is there anyone that can persaid joel to let us get his plans?

even if you got the pic killa unless your skilled with a lathe you cant build them,well thats what ive heard, you need lathe skills.

No, you need a lathe.well, thats what ive heard, you need lathe skills
Besides, all the Supah valve is is a really high quality chamber sealing valve.

yeah but even if you have a lathe you still need to know how to use it.no point having one if you dont know how to use it. 
ok lets settle this right now, im pretty sure there would only be one or two people capable on this site of building the supah.....if they had plans and a lathe(with lathe skills )

You could probably teach the averag 12-year-old to use a lathe in a manner of hours. It's not that difficult to machine plastics.

Yeah its fairly easy, I have only done it once quickly without the cutting tools but When using a file, sandpaper and rasp material comes of real easy and nicely.You could probably teach the averag 12-year-old to use a lathe in a manner of hours. It's not that difficult to machine plastics.

well everyone just says joels valve is hard to replicate and requires alot of skills

There's a difference between "skills" and "skillz". Joel has got skillz.
The difference lies in the precision and the creativity of the machinist.

He's working oversized barstock, so that eliminates the effort of precise chucking.
He then does some simple machining operations. (O-ring cutting, turning, facing, some low-precision boring)
This barstock then happens to be PVC (or maybe type-two PVC) neither are hard to work with, at all. Nice surface finish just <i>happens</i> with them, if you get my exageration, and they are rigid but fairly soft.
He then drills some holes and taps them. Again, into PVC, so it's not a really difficult activity (although I admit that tapping does take some skill)
Wow - I'd have to go to an institution for 18 months to learn how to do that!
Give me a break - none of the operations are difficult, nor will bad things happen if you have a radius .002" too big/small.
Conventional work with a fair margain for error - sounds like a fine project for someone with a few hours of lathe use behind them.

Holy crap! There's a picture of my 2" tee in that article!

Lathing is one thing, but designing something for lathe work is another. You wanna hear it BLB? Fine. You have lathe skillz. Guess what though. Most people don't.
