Xmas Posted April 15, 2011 Share #81 Posted April 15, 2011 Advertisement (gone after registration) i was going by the direction of the thread's presumption that current mp has brass. all metal composites (brass and steel) can be produced with a slightly different formula to increase "hardness" or reduce it. i suspect that as motor drives became more common, leica spec'd out a harder gear to withstand the pressure. whether the mp has brass gears or not, i will leave to you guys. but if it is brass, it is just another reason to believe the mp will be working longer after we are. Hi Well they went to steel and introduced the motor coupling at the same time - for the M4-2. Some people say they can tell the gears are brass or steel but never sure myself Before M4-2 you need a strip, mill and rebuild to fit the coupling - except for M5 it would need more radical...

Advertisement Posted April 15, 2011 Posted April 15, 2011 Hi Xmas, Take a look here M6 or MP?. I'm sure you'll find what you were looking for!
budrichard Posted April 15, 2011 Share #82 Posted April 15, 2011 From a Japanese publication 'Leica # 13' about the MP, the pictures of the disassemble appear to show brass used in some gears and other parts. I assume this was to give an M3 feel to the MP. The article compares the build, feel and sound of the M3 to the MP.-Dick Link to post Share on other sites More sharing options...
jacarape Posted April 15, 2011 Share #83 Posted April 15, 2011 So if it has brass gears, what is Leica's official take on using a Motor-M on the MP?Is there anything, to take care of ? This is a great question (the OP), one I considered before buying a used MP over a used M6. I think the true answer is cameras are like women, you'll go through a few before you end up with the one you stay with. (Not sexist, women certainly are the same!) I'm glad I chose an MP, it's what I've kept over 5 others I had. I used the Motor-M on my MP. It's pretty gentle, not a high speed thing. I really don;t think there should be a concern on that mate, other then the real disadvantages of changing bottom plates or if you have a 135/2.8.

StS Posted April 19, 2011 Share #84 Posted April 19, 2011 I would assume that what looks like brass is probably an alloy having a high brass content. Stefan Link to post Share on other sites More sharing options...
Xmas Posted April 19, 2011 Share #85 Posted April 19, 2011 Hi Mirriam and Webster say @ Definition of BRASS 1 : an alloy consisting essentially of copper and zinc in variable proportions @ It is a lot harder than copper but soft enough e.g. to re form in hand press for firearm cartridge cases. It is self lubricating with aluminium or steel to a degree that heliciods can be left dry. Noel Link to post Share on other sites More sharing options...
