supah valves

[jjk92]

i was recently on spudtech.com and saw Joel's supah valve could somebody please explaine how they work thanks

check the how to.Click Here

It wont do you any good because you cant make one and no one really knows for shure how they work

[jjk92]

kool thanks it was worth a try to save $125

[SpudStuff]

do you have a lathe and extremily good skills on it because if you dont youre wasting youre time and money.

[jjk92]

no and no thanks though

Gimme the money and parts and I'll build you one. They're not impossible to build, but it takes a lot of fine tuning and materials to get the design really close, and even then it'll be a long shot off.

It's just a chamber sealing valve with great cosmetics.

I agree with Drac-It's just a chamber sealing valve with great cosmetics, how hard could it be to build 1 like it that preforms just as well.

[SpudStuff]

well the fact that no 1 has built an exact working replica makes me sceptical.

[boilingleadbath]

People build chamber sealing piston valves all the time. They typicaly arn't built to be compact, but that's a different issue.

Really, you could build a replica without stretching your (or your lathe's) machining abilities - you'd be fine even with tolerances as poor as +-.003", which I'v learned is acctualy fairly easy.
The real reason nobody has built one is than nobody has bothered. (plus, the spudtechies would probably retaliate)

[SpudStuff]

But i thought the Spuah was a piston. is thAT THE sAME as a chamber sealing?

[Benny]

yes, also i can easy make a chamber sealing valve without a lathe.

[boilingleadbath]

It's a <i>chamber sealing piston valve</i>... the "chamber sealing" bit indicates where the seal during the static phase is made, and the "piston" part indicates that it's a rigid piston instead of a flexable diaphram.

Benny: Most likely not - O-ring grooves require a fair amount of persicion - though I'v heard of people using jigs on table saws.
Easily, though? Well...

I've used a drill press to make o-ring grooves and it worked out fairly well. Takes a really long time and is a pain (of course the ones I did were deeeeep) but it worked out. I ended up having to do some touch up with an old dremel-like tool I have. So it's not impossible to do it without a lathe, just easier.

I personally discovered table saws can make some nice o-ring grooves. Simply cheap the end tight against the fence, and cheap the wall of the pipe against the guide and just spin the pipe over the saw blade. The downsides are you cant get grooves under 1/8" wide and the bottom of the groove is lower on the sides and higher in the middle. This is because every tooth on the saw blades are angled. Every one being a "mirror" of the last.

Thats correct Pimpmann22, i took the Foley Bellsaw tool sharping course and i have a anvile made with two sides, two different degrees for different styl blades. The offset keeps the kerf/groove wider then the blade or you would get binding when making your cut. Most people think thier blades are dull when infact they are offset inproperly, or just plain gummed up.
