I built this launcher the other week it cost around £40 but i managed to scrounge a fair few bits mainly the large 35mm copper fittings as these are mega bucks (1x35mm 90 = £8-9 each!!!)
The reseaon it is entirely copper, is the fact being in the UK copper is more readily available!! also i think it looks pretty smart!!
The Chamber is made from two seperate lengths of 35mm copper 90'd and reduced into a 3/4 QEV one for each side.
The trigger and pilot are made up of 15mm copper, a blowgun for the exhaust and a shrader valve innerds removed with a check valve inbetween to stop back flow!!
The Barrel is a length of 28mm copper onto a T peice and 2x 90's fed into the twin QEV's
The Barrel is the only peice of 28mm i had left i plan to have a longer peice but not yet also i am going to add a commpression fitting to the T so that i can have interchangeble barrels
Here are a few more pics Check out my SOLDERING
- i was pretty prowd as it is my first go on copper pipe!!!!!it has also been brassod to make it all shiny - i plan to lacker it or maybe paint it????
Here's me destroying (well i say destroying more like peircing!!) a pumkin at 35psi!! - i only went to that as i have a leak past that point needs sorting!!!!!

As there is a slight leak i plan to re-design the whole back end and get rid of the fill valve and blowgun, in exchange for a single Slide valve with quick diconnect!!!!
Hope you all like - i have been into these things for about 5yrs now but i think this is my best creation to date - tell me what you all think!!!!
