the diameter of the the valve core where the pressure acts

do you know the diameter of the valve part of the blow gun? like where the pressure acts? cheers

that was epic

great video, but next time i wouldnt put music where the shooting is, its much better if you can actually hear the gun

yea my dad uses it for his work.
you mean the slots? i used a dermal tool witha cutting disk, and its only aluminium

i hate walking by the machine shop at work we have 2 CNC mills 1 CNC radial arm drill/mill and 5 lathes, so close yet so far way, hopefully after a bit they will let me use them(only my second week there). hope they let you use that stuff eventually, would be murder to have walk past that for years...

thanks but if yours can put an airsoft bb through both sides of a soup tin you defiantly have a more powerful one :shock: dont feel so bad, here you need a licence to even buy airsoft :roll: the only none basic tools i used where a dermal (kinda basic still) and a bench grinder that uses dermal tool...

My spring is the size you want :lol: what did you say? you can send it to me free of charge? ha ha i know im dreaming :P at 800 psi the bb pass through the soup tin without problem diagram, hope it helps plastic or metal bb? with the right spring mine should be able to shoot through both sides of a...

the reason why i asked is i need a 13mm OD spring to fit the inside of the tube i have the hammer in, it could be a bit smaller but i still havent been able to find one appropriate for the tube, anyways i cant get bb guns here so it dosent really matter, would really lime to see you video though, ho...

nice build, a little similar to what i have started building, except mine will only run on 400psi and the suppressor is integral, all i need to finish the workings of mine is a spring, where did you get your and how wide is it?

you could just use butane? it still makes for a powerful hybrid

JSR thanks, altho i must admit to not reading it the whole way through because must of the instructions were for people with lathes, talking about lathes congratulations on getting yours :) i did however attempt making a spring from what i could understand of it, and it kinda worked, i mean it was a...

i am currently attempting to make a low powered PCP air gun and am stuck on what spring i need and where i can get it the hammer valve seat diameter is 10mm pressure when full 400psi hammer weight 60g hammer length 4.5cm distance between valve and back of hammer tube 12.5cm OD of the spring needed 1...

sorry but i dont think i could understand most of your post, so you have started to make it? if so some pictures would be nice, and and there was a vid of the valve on the second page, but because of the constan flow it was going to fast, could have possibly worked with a lot of tweaking but i had l...
