bankz5152 Posted April 22, 2014 Report Share Posted April 22, 2014 Hey Chaps, Need a little advice here. I currently have around 8 Gen.1 WE Mags which are all leaking rather badly from that silly back plate design. The plan is to upgrade to Gen.II innards when funds allow but would like to get these working in the mean time. Anyone had any success using a bonding agent, glue or even welding the back plate shut to create a leak free seal? My first idea is to use to remove the backplate rubber seal and then seal Tigerseal. I mean this stuff holds body work together on cars so should be up to the task. Anyone got any other ideas? Link to post Share on other sites
renegadecow Posted April 22, 2014 Report Share Posted April 22, 2014 Uh, aren't gen 1 mags the ones that blow up? Gen 2 mags have an internal reinforcement but still use the wonky gasket while 3 (current) uses o-rings and should be what you're after. As for sealing them, black RTV silicone sealant works in a pinch but I've observed the pressurized silicone oil in green gas eats it away in time which is why I've switched to latex based sealants. edit: Forgot to put how. Disassemble completely including the gasket from the plate and clean with acetone. Apply sealant to plate then install gasket on plate. Put sealant on gasket and a thin layer on the mag then put the plate on. Tighten screws evenly (not one completely then to the next) to squeeze out excess sealant and air bubbles. Let cure 24h before applying pressure. Link to post Share on other sites
bankz5152 Posted April 22, 2014 Author Report Share Posted April 22, 2014 Only two gens as far as I know. Back plate design and the split chamber design. Only reall use dry propane so shouldnt be too much of an issue. Cheers for the stripping info wasnt too sure on how to do it! Link to post Share on other sites

bankz5152 Posted April 22, 2014 Author Report Share Posted April 22, 2014 Woah. Holy *suitcase*. Never seen that before!! Not noticed any blugeing or warping on the magazines. Did that blow through the outer shell? Link to post Share on other sites
renegadecow Posted April 22, 2014 Report Share Posted April 22, 2014 Not sure on that one, but this one definitely did: I can't remember exactly how to tell 1 and 2 apart, just that it's to do with the mold seam at the bottom of the gas tank near the fill valve. One has a line parallel and the other perpendicular, you'll just have to check the earlier pages of the review thread to be sure which is which. edit: just checked, parallel with the mag is gen 1. and perpendicular is gen 2 Link to post Share on other sites
calbur20 Posted April 22, 2014 Report Share Posted April 22, 2014 One seam at the bottom means danger, steer clear. Two seams means it's GTG. Link to post Share on other sites

Danke Posted April 22, 2014 Report Share Posted April 22, 2014 You can rebuild them with gasket maker like you'd use in an engine. They will still start to leak though; that long cover is an Achilles heel. Here is a how too thread for the repair. http://www.airsoftcanada.com/showthread.php?t=107493&highlight=gasket Link to post Share on other sites
jkpics Posted April 22, 2014 Report Share Posted April 22, 2014 Use rigid gasket maker, I tried with some blue stuff and 5 of 6 mags leaks. Link to post Share on other sites
Danke Posted April 22, 2014 Report Share Posted April 22, 2014 Be careful with too aggressive a material. Chances are good that a leak will reappear over time and you'll need to clean it out and repeat. If you've JB Welded them together that may be impossible. Link to post Share on other sites
renegadecow Posted April 22, 2014 Report Share Posted April 22, 2014 Yeah, had to fix a couple mags whose owners used steel epoxy of all things. All that goop and they didn't bother degreasing first. No wonder it didn't hold up. Link to post Share on other sites
Stuey Posted April 23, 2014 Report Share Posted April 23, 2014 So this is actually the 3rd iteration of the design. Those are some scary pics of the old mag. I've only taken apart one of the 'back plate' design and I remember thinking it was incredibly dumb at the time. Ditch them asap! Link to post Share on other sites
Katotaka Posted April 23, 2014 Report Share Posted April 23, 2014 The upper-lower design ( I refer those as Gen 2 ) mags are virtually trouble-free. I got like........ 8 of them now and the my old gen mags are "chopped" for extra mag parts............ tried sealing them with blue RTV but leak again after few months, not sure if I did the job bad or what...

bankz5152 Posted April 23, 2014 Author Report Share Posted April 23, 2014 They will eventually be upgraded. Its mainly so I have some mags for the time being. Got one mag all cleaned up with acetone, used tiger seal to bond the gasket to the plate then more to bond to the main shell. Should hold for a while at least. One of the mags was an original gen1! On my phone, my spelling will suck. Link to post Share on other sites
uscmCorps Posted April 24, 2014 Report Share Posted April 24, 2014 Seeing those pics of the exploding WE gas mags reminds of the exact reason why people in the know in the RS world say that the magazine and mag well are NOT supposed to be grips. Catastrophic failures with rounds in mags aren't common and while they rarely happen, you don't want your hand anywhere near the magazine and especially not grasping it. WE … so real it'll blow your hand off. Link to post Share on other sites
bankz5152 Posted April 24, 2014 Author Report Share Posted April 24, 2014 Makes sense! Repaired one the other night, tested it last night. Holding gas with zero leaks! So that one is doing nicely. Did 3 more last night but I found on two of them it was almost impossible to screw some of the back plate screws back in! So more tigerseal went in there... lol Theses only really have to last me around 3 weeks until places are restocked. If my 416 ever arrives that is.... Link to post Share on other sites
