going slightly mad trying to find a hose barb :( (question)

First of all sorry if this is in the wrong place or breaks a rule, I've checked and I'm fairly sure it doesn't.

I am attempting to replicate the above re-setting piston design (courtesy of spike33127), with 10-25 mm fittings from Bunnings in Australia, and I can't find a hose barb, does anyone else from aus no where I can get one? (I have used the search function, with search for all terms on)

Oh and so that this post isn't just me being annoying and asking a question, I think Spike33127 uses this valve for a multi shot airsoft plinker that I posted awhile back, if anyone else is interested.

i think it might be a barb for a garden hose

you don't have to copy his design... build your own with whatever you have at hand

i couldn't find them at bunning also, so brought a 3/4 inch barss nipple cut one end off and soldered a small section 1/2 inch pipe into it.
