just passing my plans by you guys.

[pyromanic13]

ignore the stuff on the right side it won't make sense you guys.

please tell me if I forgot any parts, or if I won't get decent range, ect...

thanks in advanced!

[saladtossser]

good effort, but not all the needed parts are there, unless this is only a concept drawing

you are missing:

parts needed to connect the 2" pipe to the 1" threading of the spinkler valve, you can not find just ONE thing to do that.

a nipple connecting the blowgun to the valve

you forgot to lable the 4" to 2" bell reducer, which could be hard to find, you should make that a 4" to 2" bushing and a 4" coupling.

[CS]

Just a simple inline pneumatic, dont see why it wouldnt work.

I notice that on the chamber side, you have a '2"x5"' length of pipe to connect the two fittings. Do yourself a favor for asthetics and measure the socket depths of both fittings and cut the pipe ~.125" under so the fittings sit flush agaisnt each other. Better yet, follows ST's advice and do the transtition (Reduction) with bushings rather then the method specified in your diagram.

[pyromanic13]

ok I changed it to this point, could you list the parts needed to bring it from 2 inch smooth to 1 inch threaded please?

thanks, this is going to save me from sitting at home depot makeing last minute adaptations.

Buy two 2" slip x 1" female threaded bushings and 2 1" nipples.



woah salad's bunny is amazing

[SpudStuff]

WTF Pyro there is nothing in your post.

Yes use the bushings and nipples If you want you can glue the nipple into the bushoung to make it easier to remove the valve

[pyromanic13]

ok sounds good

oh and spud stuff, I was bored so I made a post with nothing in it...

[pyromanic13]

do they make pvc parts that look like couplings but are threaded on the inside of BOTH parts?

[noname]

You can get steel and iron like that, but I'm not sure about PVC.

[schmanman]

yeah, you could use a steel threaded coupler. it would work just fine.

[pyromanic13]

but don't the steel ones get smaller the farther down you go?

[schmanman]

no,they don't, I've used them before. maby slightly , but only very slightly

[Shrimphead]

IIRC, all npt threads are tapered.

ok so this is what I've got now. tell me if you see any ways I can reduce the # of fittings I have to use. thanks! I can list them if I must...

I'd like to use mostly pvc parts, in the context that I'd like it to be as light as possible.

[BC Pneumatics]

Pipe Threads taper down as you go. Look at any nipple or pipe tap, and this will become obvious.
