Schaap Posted September 18, 2012 Author Report Share Posted September 18, 2012 The included drawing is modeled after the original shell door without any modifications. As I said, it could be a little off, due to the "complex" shape of the part and the limited amount of measuring tools I have. I milled the nub off my shell door and made some inserts for it. Problem was, space if very limited and I had to make it longer to attach it with a screw (from the outside, threaded in the insert), which caused shells not to eject. After a little filing on the inserts, shell ejection was very reliable and strong, but the inserts are tiny. I've got another concept with bigger inserts that are identical to the original nub. I'll post it sooner or later. What material did you print the door in? Link to post Share on other sites
Vilreen Posted September 18, 2012 Report Share Posted September 18, 2012 That "Strong" plastic Shapeways has. I thought it would be great, because you can adjust dimensions more easily then in metal. And it's cheaper I thought about an idea similar to yours, however I don't have tools to do that, and lets say I would like something more elegant than a screw fix Or more easy to manufacture. But ofc I may have to do a screw fix, if all else fails... Link to post Share on other sites
Bannog Posted September 21, 2012 Report Share Posted September 21, 2012 There is a way to reduce the wear on the shell ejector which is to fit a fine O ring around the brass base of the shell. This has the effect of cushioning the ejector nub but still allows for the shell to be ejected. Worked fine on mine as I have virtually no visible wear on the ejector nub after a fair few hundred rounds through it. My shell loader failed before the ejector nub. There's a thread about how to repair a worn ejector nub here : http://www.airsoft-barracks.com/forums/topic/14752-problem-solving-guide-for-the-maruzen-m1100/ Apologies if I'm not allowed to post links to other forums.

Vilreen Posted September 24, 2012 Report Share Posted September 24, 2012 In my case, fitting an O-ring didnt make any difference whatsoever to the mechanism. It works almost flawlessly on 134a (and simililar) gas, doesn't work at all on green gas. When I've tried to fit more then 1 O-ring, the gun didn't work at all, the second oring was blocking the shell ejector-door almost everytime it tried to cycle. Link to post Share on other sites
philsus-fubar Posted November 18, 2012 Report Share Posted November 18, 2012 still cant wait for the full kit! any news on when it will be on the market or how much? Link to post Share on other sites
SilentObservant Posted November 23, 2012 Report Share Posted November 23, 2012 I'd totally be down if it can use the furniture from the real thing. That would be amazing, even if there would be heavy modification required on the RS parts to get them to fit. I wouldnt mind modding it. Hoping for updates in the future, hope all is going well.

TnL Posted January 25, 2013 Report Share Posted January 25, 2013 Hey guys, I don't know how common this problem is, but I think ive seen it a few times, but if the arms are broken off of your bolt cover, I have repaired mine in a way that has proven reliable, if any1 cares, i can post the solution...

theunknownpooper Posted February 18, 2013 Report Share Posted February 18, 2013 have you made a shell catcher? guns useless playing without some to effectively catch all the shells Link to post Share on other sites
bankz5152 Posted February 19, 2013 Report Share Posted February 19, 2013 So someone makes something this incredable and you ask Does it have a shell catcher ... That is a £10 extra that is nothing to the integral build... Sent from my GT-P5113 using Tapatalk 2 Link to post Share on other sites
theunknownpooper Posted February 19, 2013 Report Share Posted February 19, 2013 its incredible no doubt, but im curious how people play with this if there isn't a shell catcher. no need to be rude buddy. I'm looking into the 1100 but backed off due to weak internals and this has no doubt got my interest and support. Just need to figure out how to get a box onto it. Link to post Share on other sites
notrabies Posted February 19, 2013 Report Share Posted February 19, 2013 In my 2+ years of skirmishing with my M1100's and M870's, I've never ever used a shell catcher, and I've probably only lost about 5 shells or less. Most of this comes from playing at an indoor field, but if you play it safe its really not an issue. Certainly not as run-and-gun as an AEG, but a simple change and tactics will accomplish the issue.

theunknownpooper Posted February 20, 2013 Report Share Posted February 20, 2013 So what do you do? Play the whole round and hope no one steps on it then pick it up after? Confused on how that works, but trying to understand. I think realisitically for me I will have to make a shell catcher. Do tell me know how it works though, really curious Link to post Share on other sites
TnL Posted February 20, 2013 Report Share Posted February 20, 2013 personally, I do all of 3 things depending on circumstances, in a hot firefight I just shoot and go, come back later, if im in a peek a boo battle, 1 shot, into cover, eject into my hand and stow (only works with the 870, not the 1100), go again, or i just fire, and then after the engagement is over I collect all the shells in the area then move on also its unlikely that they can get damaged too badly, theyre just plastic tubes with a little brass rim on hte back and theyre pretty tough Link to post Share on other sites
notrabies Posted February 20, 2013 Report Share Posted February 20, 2013 Yeah, while a few of my shells have been cracked after being stepped on (on concrete) most either take it, or slide out of the way. My tactics are pretty similar to TnL's, when firing I generally stay in one area and pick up shells when it calm, but most of the time I merely wait until I've been shot and pick them up on the way back to the respawn.

Wingmann Posted February 20, 2013 Report Share Posted February 20, 2013 I've been designing a mech for a shotgun with the following specs 3 or 5 BBs. using TM "shell" magazines. using external gas. True semi auto. GSBB, (Gas SemiBlowBack) meaning its a GBB mech, but with no weight in the bolt so you don't feal any recoil = best of NBB with a light trigger. Some sort of "saftey bolt stop" so that if it dosen't feed a full load it dosen't fire. Solving the problem of the last shot putting holes in people. Once I've got the internals sorted, ill start a company and all the other things we do in dreams . So, how close are you to this late 2010 idea? I'll take one Link to post Share on other sites
TnL Posted February 20, 2013 Report Share Posted February 20, 2013 the original maruzen defender already exists, gas powered, GBB, magazine fed, 3 BBs per shot, been around for many many years Link to post Share on other sites
theunknownpooper Posted February 20, 2013 Report Share Posted February 20, 2013 Very interesting, thank you for the responses. I hope to buy from this man, have been research on these shotguns for awhile now and it just seems like the internals are pretty weak and cannot handle abuse so I'm glad I found this thread. Only thing I wish not to do is the HPA tapping. I'll have to save up money so I can purchase a set of internals! ^__^ Link to post Share on other sites
TnL Posted February 20, 2013 Report Share Posted February 20, 2013 the M1100s are pretty hard on themselves just in the nature of being a GBB, but the maruzen M870s are surprisingly tough Link to post Share on other sites
Schaap Posted February 20, 2013 Author Report Share Posted February 20, 2013 Only thing I wish not to do is the HPA tapping. I was a little skeptical about this at first, but when you want the skeleton stock, this is the only viable option. The grip gas reservoir found in the M1100 Revision simply does not provide enough capacity if you plan on skirmishing with it. My M1014 receiver should fit a full stock without problems, allowing a larger gas tank. Link to post Share on other sites
ED-SKaR Posted February 21, 2013 Report Share Posted February 21, 2013 So, how close are you to this late 2010 idea?

TnL Posted May 4, 2013 Report Share Posted May 4, 2013 the valve itself goes in from the front and you hold it back with a tool of any sort, and them put the brass cap with Ring and then C clip on hte end Link to post Share on other sites
theunknownpooper Posted May 6, 2013 Report Share Posted May 6, 2013 Ahh theres more to it, guess I'll have to keep playing around with it, I had to take it apart because the oring was damaged but I should have taken a picture of the order, my fault Link to post Share on other sites
