ED-SKaR Posted March 1, 2016 Report Share Posted March 1, 2016 How does it work? Link to post Share on other sites
renegadecow Posted March 1, 2016 Author Report Share Posted March 1, 2016 Fill the back with a bicycle pump up to 100psi, load the barrel with shot, and throw the switch on the battery for the solenoid to fire. Link to post Share on other sites
GI0VANNI Posted March 1, 2016 Report Share Posted March 1, 2016 As far as I see it t is a complete marvel for 30$, and would fit inside mine so pack it and sell it!!, this time you will have no issues with "gun shape" and all the like as on previous occasions and you would get plenty of players happy with your skills (again). If some people pay hundred for a gas sister for AEG bodies why not pay that for a "mortar/launcher.... inner sister that is RC proved? Link to post Share on other sites
ED-SKaR Posted March 2, 2016 Report Share Posted March 2, 2016 Fill the back with a bicycle pump up to 100psi, load the barrel with shot, and throw the switch on the battery for the solenoid to fire. Teach me sempai. Or, better still, make me one. Link to post Share on other sites
renegadecow Posted March 2, 2016 Author Report Share Posted March 2, 2016 I think I'd rather teach you. Not that I have much of a choice, neck deep right now in Stat Wars riot batons, but that's a different story. To start off you need: 1x 12V 1/2" normally closed solenoid valve ($4 on eBay) 1x 12v lithium ion rechargeable battery ($10 on eBay) 1x Schrader valve 1x 1/2" PVC pipe 1x 1/2" PVC end cap 2x 1/2" PVC threaded adapter 1x PVC solvent cement Link to post Share on other sites
paranoiddroid Posted March 2, 2016 Report Share Posted March 2, 2016 Checkout nighthawkinlight on YouTube for a guide to build an rpg similar to this coaxial piston air cannon is the video title I want to use it to make a mortar. Link to post Share on other sites

blobface Posted March 2, 2016 Report Share Posted March 2, 2016 What are the projectiles? Link to post Share on other sites
renegadecow Posted March 3, 2016 Author Report Share Posted March 3, 2016 Just bbs for me. Got maybe 10kg of bbs caught in my target trap that I can reuse. But really, anything that fits snugly in the bore will launch. So put on a different sized barrel (and air chamber to match) and you can launch soda cans, tennis balls, t-shirts etc. Link to post Share on other sites

Roland1014 Posted March 6, 2016 Report Share Posted March 6, 2016 I dreamed up something like this except it fired a tag out the front and a dusting of flash powder out the back to simulate back blast. Link to post Share on other sites
renegadecow Posted March 7, 2016 Author Report Share Posted March 7, 2016 Finally got to test it in the field and it's pretty impressive, maybe switch to a 1" pipe for the tank just to give it a little more oompf. As it is, a payload of about 150 bbs (mostly recycled .25g) does 200fps at a max 100psi. Range is limited obviously, but flat aiming is good to 20m and lobbed can reach up to 40m, 50m at a severe angle. At 20m the spread is already the size of two doors but could largely be influenced by the mixed recycled ammo. While working on the externals, I'm thinking of making a few compact (tank folded over beside barrel) econo version using a ball valve instead and leave them scattered around the site to be used if picked up and possibly have them as part of a scenario.

ED-SKaR Posted March 7, 2016 Report Share Posted March 7, 2016 I think I'd rather teach you. You've lost me already :/ . If you can find the time to write a full tutorial, that would help. I've had a CO2 paintball tank and palmers regulator for so long and I've never actually used it, time to change that. Link to post Share on other sites
renegadecow Posted March 10, 2016 Author Report Share Posted March 10, 2016 I'll make a tutorial when I assemble the 2nd solenoid driven launcher. But for now, I had to swing by the hardware for paint so I thought I may as well get some fittings for the down and dirty version. This one doesn't even reach $10 in cost! Threw in my P90 to scale, it's got a 20" barrel and the tank (now fattened to 1") is folded over to save space. Still figuring out how to hold it, but right now the best I've come up with is firing it like a knee mortar. Link to post Share on other sites

paranoiddroid Posted March 12, 2016 Report Share Posted March 12, 2016 Is that basically a coaxial piston air cannon? Could always rebuild it in a similar vein to the commando mortar? Link to post Share on other sites
renegadecow Posted March 12, 2016 Author Report Share Posted March 12, 2016 I dunno, wouldn't that mean having the barrel and tank sharing the same center like the TM Uzi? Anyway, I woke up this morning and just turned it into this. You can clearly tell I have no idea what to make of these things. Link to post Share on other sites
ED-SKaR Posted March 12, 2016 Report Share Posted March 12, 2016 Can you get a solonoid that opens and closes in succession? I'm thinking of using it for a faster* firing NBB system fed from an external co2 rig. *Faster than a bicycle pump :/ Link to post Share on other sites
renegadecow Posted March 12, 2016 Author Report Share Posted March 12, 2016 They open and close nearly instantaneously so in a way you can just control it with your trigger finger. But for something like full auto you're gonna need more complex circuitry. Link to post Share on other sites

But for something like full auto you're gonna need more complex circuitry. I'm thinking of a single shot weapon, possibly another RPG7 but more likely a smaller launcher(40mm) or perhaps a breach break shotgun(12bore) dependant on how the thing ends up looking (if I ever build it, that is) Link to post Share on other sites
renegadecow Posted March 12, 2016 Author Report Share Posted March 12, 2016 You're over thinking it! The above wasteland shotgun was literally made between breakfast and lunch plus 30 minutes of assembling the plumbing bits a couple days prior. Unless you're really after making a replica of something, the fun part with these is letting your imagination run wild. Link to post Share on other sites
