Its not done yet i need to get 3 O-rings and fille in two more groves in the nuts, ill try go to bunnings tomorrow. The tees are 1/2'' i used 3 nuts and a peace of all thread for the rod.

i should have gone with 3/8 because this thing is massive, its bigger than the 3/4'' valve its going to pilot :lol:

It definitely looks good but lets see how it performs under high pressure conditions. Are you planning to use Locktight or something on the nuts when it's finished?

Another idea would be to squeeze a rubber gasket between two nuts and two washers, put the all thread into a drillig machine and grind the gasket down with a piece of sandpaper till it fits perfectly into the 1/2" nipples.

Overall it is a good idea to use a threaded piece of rod. The way I built my 3-way was a p.i.t.a. :)

or you can use a threaded rod to build a spool... you just need a few metal washers and some nuts... I've never tested thi but I guess it should work fine

i whet to bunnings today and they don't have any orings the would fit, tomorrow ill try to squish a bit of rubber in between two nuts like MMR said.

i was gonna put epoxy in place of locktight because that stuff it a rip off at bunnings.

i would get you to machine a sleek one but i got a new job and they are teaching me how to use the lathe and mill, so hopefully they let me make some cool stuff. i only work on fridays its like work expenince but for a hole year aka vcal (victorian c.unts are lazy)

thanks for the kind words.

in that pic the valve it filling the gun. but if you push the nut across a bit the first tee is sealed and the second opens up piloting the gun
