Hi everybody, I bought a drill press last weekend so I decided to try this out.
But I don´t need any piston right now and I got a lot of nylon block from a friend, so I thought I would try to make my own 3 way 2 position valve :P
Can´t belive I actually did it :o , I almost got this thing finished only missing one more piston and a cap.
Here are some pictures, not going to use more than 10 bar so I´m pretty sure it won´t explode :D

warhead052, everything you need to know is in the tutorial.
Finished! I´m so proud of myself :P this is the second time I use the drill press and I think I did great 8) (the first time I turned some aluminium/nylon to choose witch tools I should use as the blade and see witch speed I should use).
The valve leaks a little when changing the flow, but very little as I can press the stem fast.
specifications:
valve body: nylon
type: 3 way 2 position
working pressure: 10bar
size: 5.5x3x1.5 cm
orifice: 6mm ID

I only used 2 o-ring seal, so there is a small leak when changing the air flow

It's already finished :roll:
And it works great, now I only have to decide the size of thread I should use.

Very nice work, if you can get a nice chunk of aluminum I'm sure it could take a few hundred psi. I thought about making one of these if I could get a suitable body material.

Nice work :)
I am trying to make a custom valve on my newly acquired Lathe/ mill and learn how to use it.

HA, I completely forgot about poland's obsession with 3way's (that might have a double meaning, who knows).
