Sweet! What is that? Reminds me of a heatsink but i'm lost as to why it has a hole in the middle tho... It came from an event company in The Netherlands, so shipping was doable. https://www.fritz-events.nl/adam-hall-aluminium-x-profiel-7mm.html Just got back from vacation so i'm gonna clean up my wo...

Thanks for the input! I'll keep a design in mind with a longer tail section and where the body of the round tapers down to the piece if wire rod that holds the fins in place

These also look good for making some folding fins too!

I have just ordered a piece of aluminum profile tubing that has a shape for which i've been looking for a while: Xporfile.1.jpg I was thinking of cutting like 2cm long pieces of this piece and attach those to a piece of wire rod to serve as 8 mini fins. Wonder if this would be accurate? If the proje...

If you don’t mind ordering than this sort of thing would be ideal. I believe the fittings are generally 1/8” thread. https://www.amazon.com/Paintball-Airsoft-Refueling-Stainless-Disconnect/dp/B0727QF3PV/ref=mp_s_a_1_50?ie=UTF8&qid=1530499114&sr=8-50&pi=AC_SX236_SY340_QL65&keywords=paintball+fill+ho...

Allright thanks! I'll use a one-way female QD for the main chamber and a male side for the pilot, my fridge comp already splits into two lines so it's less of a hassle than it sounds like. The pilot is operated by a 1/4 QEV which again is piloted by a 1/4 solenoid valve so using a female QD for the ...

I have used just basic quick disconnects at 40bars without a problem. Only the "disconnecting" needs a bit more force than in normal 8 bar use My current fridge comp set-up allows me to bleed the lines before disconnecting so that should be no problem. Any difference between the brass ones and the ...

Yeah but i think they are sold in fixed lengths, and this tiny fridge comp is already so slow. I'm now aiming more to replace the union fittings with high pressure QD fittings, perhaps i could keep using the copper tubing that way. Any idea on what the regular DIY store QD's can handle? I could just...

Perhaps hose for a high pressure cleaner? EDIT: These probably have some kind of proprietary fitting so that's probably not an option. There are so many guys here using fridge comps, what do you guys use to connect it to your cannons?

I don't see a max pressure stated on the website tho? it still looks rather rigid. I've seen them before in construction works. I'm currently working with 8mm OD copper tubing and brass union fittings but it's a mess and i need to tighten them so hard with a wrench that the soldering often gives or ...

Short question! How much PSI/BAR can those clear braided hoses from the general DIY stores handle? Looking for a more flexible way to pressurize my cannon with a fridge comp at about 40bar MAX.

Update: Fix one leak = find three smaller ones... I'm gonna have to take the entire valve apart and and use the sealant on the actual valve stem and a screw that i used to seal off a wrongly drilled hole i once made. Also, filling the chamber is a true pain because i use 3/8 union fittings to attach...

Ok i went to some basic DIY stores but hey did not not stock any decent epoxy except the ones from Bison so i went to a more specialized store and found that they actually had some professional pipe sealant that goes up to 2" fittings so i got that, it's curing now :) I'ts a busy period for everyone...

Yeah i have another package from the US that is currently held by customs... First few test shots were promising. It actually made a bang instead of a whoosh with the QEV, yet the large clumsy 2" pipe parts that make up the camber are leaky as hell no matter how much i wrap them with gas grade teflo...

Not leaving you guys hanging here but the QEV arrived only yesterday after me posting that i ordered it... Took over a month to get here god, if some of those China sellers would just offer a slightly faster shipping service for like 10$ instead of the free one taking over a month i'd be all over it...

Well I have to chime in here, can't be having you dragging an extension lead around to plink. You don't need AC to run one of those solenoids. 24VDC is perfectly acceptable. But easier yet, just use three 9 volt batteries connected positive to negative, in series. That'll obviously give you 27 volt...
