Progress is bad, I waiting on RadekB to do another test samples to glue - with little space now, so the crackings on gluing did not happen again
Trust me, I would like to know that things will work too, but... :shrug:
Probpems, problems, problems...
Anyway, yes, you can screw there any barbs you like - as long it have the 1/4" NPT thread (optionaly 1/4" BSP one) - and yes, as I already 2 posts back pointed out, McMaster-Carr selling suitable 3/4" barbs (with the 1/4" NPT thread), so you can use them easily
