poosh507 21 Posted May 10, 2015 Report Share Posted May 10, 2015 Could anyone tell me the inner diameter and outer diameter of the shell of the drum? Quote Link to post Share on other sites
poosh507 21 Posted May 10, 2015 Author Report Share Posted May 10, 2015 And to clear things up I am planning on making a s20 drum mag and would like it to be the same size as the md drum but maybe hold more shells. Still drawing up some designs Quote Link to post Share on other sites
gunfun 3,931 Posted May 11, 2015 Report Share Posted May 11, 2015 Lots of old threads like this. You are trying to take on a very difficult thing than few have made work. Quote Link to post Share on other sites
poosh507 21 Posted May 11, 2015 Author Report Share Posted May 11, 2015 That's ok, I like a good challenge. This will be the last thing I do anyway, I have a lot of work to do on my stock saiga 20. But when it's done this will be my next project. And I have a few designs drawn up. Where might I find such old posts? Quote Link to post Share on other sites

poosh507 21 Posted May 11, 2015 Author Report Share Posted May 11, 2015 I've searched "homemade drum mag" and similar things like drum mags in general and haven't gotten anything. Quote Link to post Share on other sites

poosh507 21 Posted May 11, 2015 Author Report Share Posted May 11, 2015 you want some "cheesy poofs"? you better get some, its going to be a long road to what will probably be my failure. Quote Link to post Share on other sites

poosh507 21 Posted May 11, 2015 Author Report Share Posted May 11, 2015 Yeah....no clue what to call it...does it look ok? and are there any posts on this? I honestly couldn't find any Quote Link to post Share on other sites
poosh507 21 Posted May 11, 2015 Author Report Share Posted May 11, 2015 I was going to solder a ton of ar mag springs together to make the spring for the first one. And buy a saiga 7.62x39 drum spring for the second one or find one a store. And all the dimensions of the drum are scaled down exactly one half what it will be. Per the measurements of the piping and shell rim size. So that's around the exact number of shells it will hold. Plus/minus 1-2 that's if everything goes well. Quote Link to post Share on other sites
Dad2142Dad 6,559 Posted May 11, 2015 Report Share Posted May 11, 2015 Well you could always buy a drum from MD and use it to get your measurements. But you must realize patents are in place. 1 Quote Link to post Share on other sites

poosh507 21 Posted May 12, 2015 Author Report Share Posted May 12, 2015 True patents make it hard to copy the size. And I don't think I want to buy one because I don't have a saiga 12. And I don't think the md drum follows the designs I put up. Quote Link to post Share on other sites
