Pictures of Valve building
Just some pictures of building a valve.
Takes about 4 hours to build one from scratch.

looks great.
Riff raff,
I was only funnin’. 😀
Didn’t even notice the damn date on this.. whatever, ‘t was still interesting to see. So necroing it wasn’t all bad..
Oh, do you take paypal? 😀
I’m not sure he ever made these for sale. It was 2007 at the time, so today who knows?
I’m no expert but judging from the pics you kind of fill it the same as the normal valve..
Pretty neat way to machine the ports if you don’t have an indexing table, by the way..
Really impressive. Please keep the photos coming.
Oh, do you take paypal? 😀
How you will fill the tank with this valve?
That is fantastic! man I have had nightmares making those ports with a hand drill and dremel tool. I tried using my drill press but the bit kept slipping and it was nearly impossible to line up the hole correctly without some kind of cross slide vise.
Thanks for the info on how you make a valve this is really interesting and useful.
Of course feel free to post any other machining info you want to!!! I took machine shop for 2 years in high school and worked in a shop after school but I only know the basics plus a little I learned making a couple Titanium valves.

Thanks!
The steel for the stem is drill rod, and has a 3/8 – 24 external thread to accept the large part of the tophat. There is a brass ring (large part of tophat) .5 in diameter and with a 3/8-24 internal thread. This allows tophat adjustment.
Check out the pictures below. they are not from this 3 port valve, but were from a 4 port valve. The setup is the same except I use a hex collet fixture insted of the square one in the picture.
CUTTING THE VALVE STEM PORTS IN A MILLING MACHINE:
THE STEM IS HELD IN A SQUARE COLLET FIXTURE IN THE MILLING MACHINE VISE
CUT A PORT, THEN ROTATE THE FIXTURE IN THE VISE TO CUT THE NEXT PORT
PLUNGE DOWN WITH THE CUTTER IN EACH HOLE TO SMOOTH OUT THE PORTS
MM what a frigging fantastic post!!! That is a really cool design on that whole setup.
The brass? piece the spring is against, how is that setup? threaded? adjustable? was curious why you didn’t use steel 1 piece steel for the whole thing?
What steel did you use?
How do you drill the ports?
Thanks for sharing!
Jim.
Cool JJ !
send pictures!

making an adapter for my digicam and t-scope
5 hours 🙄 😳
60 mm brass tube woulnt stop wobbling (i think it was the bearings straining under the weight) 😆
one of the best things i made was a die holder,it makes things so much better 😉
JASON.. 🙂
You are blessed with an awesome skill. 8) 8)
