Cheap n easy needle valve for a Boka

Postby Flowerpot » Thu Sep 15, 2016 9:31 pm

When I first started making my boka I was continually frustrated trying to find an ok valve for a reasonable price, Ebay was order wait wait wait and find out it was crap. Trade suppliers rip cash customers blind. :angry-banghead:

Anyway had a think and came up with this:
Everything needed : Copper Tee, coupling, two bits of 12.5mm copper rod, and a stainless 6mm bolt.

Put a taper on the bolt. The slower the taper the finer the control.

Solder The copper rods into the ends of the tee

Measure the size where you want the taper to engage. Root of a 6mm bolt is about 5mm so 4.5mm is good.

Drill a hole all the way through both ends 4.5mm

Drill and tap for the thread being careful to only drill through the "top" section

Solder the coupling on, give it a clean up, complete.

:happy-partydance:
I used a lathe but it could easily be done with a drill press, or even a hand drill if careful. It gives really fine control BUT it is not really well sealed so the top of the valve should be above the maximum liquid line in your slant plate.


Cheers, I'm having a drink. :obscene-drinkingcheers:

Cheap. Not sure about easy. Definitely beyond my abilities and tooling.
Good little instruction manual for those that do have the gear though. :handgestures-thumbupleft:
