Drum beat! lessons learned!

[G.T.]

Hi to all! We'll the drum revision project continues to slog along with me trying to find alternate methods of surface prep in order to rein in some of the hours of labor involved? Every once and awhile, I learn something new, and if I don't write it down, I forget it soon after discovery....... so here is the latest little discovery for your enjoyment!
First I must explain, that the drum / Luger combination requires that both units are up to tip top performance condition, and so it is with my testing Luger for cycling the drum thru its 32 round final bench test. So, say I test each drum twice, that's 64 and lets say ten drums being tested, that's 640 rounds cycled thru my test pistol. now lets take that out to 200 drums... That 12,800 cycles.... not one bang, all done with dummies and by hand...
So, even when I have revised the drum to perform 100%, I still might have malfunctions with the Luger being at fault... along the way, you become acutely aware of what part might be failing, and what to look for, or so I thought until my latest experience...
When cycling the Luger with the drum, I look for positive extraction, and positive ejection, the philosophy being you can't get a new round in, until you get the old one out? So, when I start getting rounds just dribbling out, I look first to the extractor and spring, usually a new spring and a swapped out extractor cure it up... Or, in my case, I replaced the ejector as it had actually hammered it's self loose and a new tight one seemed the way to go? But, still the problem stubbornly refused to be corrected, so I though all that's left was the breechblock, and having some brand new VOPO breechblocks on hand I put one in and tried to cycle the round thru... What I got was a surprise! The round was ejected so positively and violently it caught me completely off guard, missed my brass catcher, and narrowly missed my home computer screen on the other side of the room!!!! ... Holly crap Batman!! Guess what, breechblock condition, or maybe face condition has A LOT to do with positive and hearty ejection!! Annnnd, so endith the lesson for today! .... best to all, til...lat'r....GT
