jason_b. Posted January 17, 2005 Share Posted January 17, 2005 Do the Wasserman cranks designed for the M2/3 fit the new MP? Link to comment Share on other sites More sharing options...
roger_michel Posted January 17, 2005 Share Posted January 17, 2005 i think i tried mine (new gen wasserman -- i.e. less nice finish) on my MP and it did not work. too thick as i recall. i am not sure how careful wasserman was with consistency of materials, etc. it may be that you have to try to be sure.

roger_michel Posted January 17, 2005 Share Posted January 17, 2005 yep -- mine no work on MP. Link to comment Share on other sites More sharing options...
ben z Posted January 17, 2005 Share Posted January 17, 2005 There seems to be less clearance between the knob and the indent in the top plate on my MP than my M3. The Leica add-on crank is completely open on that side and seems to fit my M3 ok (though I'm not going to use it until I modify it), the other cranks in existence go clear around the knob. The one Photo Products sells for $99 on their website (and Photovillage sells for $119 on theirs) was designed post-MP so it _should_ fit either. I guess it depends on how thick the Wasserman crank is. What puzzles me about all these cranks is why they are made with a setscrew that goes toward the knob, as the retentive force is only at the point of contact of the setscrew and 180 degrees across from it. I can't understand why these cranks weren't made with a split in the screw end and the screw running 90 degrees to where it is now. That way as the screw was tightened it would apply nearly even force all the way around the knob (like a hose clamp) and there would be no need for plastic plugs to prevent damage to the knob from the screw digging in.

brunom Posted January 17, 2005 Share Posted January 17, 2005 Ben Z I've not seen this particular crank in the 'flesh', but if it works ok then maybe it's because the design used is more elegant? Regards Bruno Link to comment Share on other sites More sharing options...
emanuel_lowi1 Posted January 17, 2005 Share Posted January 17, 2005 There is a definite difference in spacing re: rewind knob on the M2/M3 vs. the new MP -- clearance is much tighter on the new MP. But bear in mind that even among the M2/M3 cameras, and among the latest MP cameras, there are variations in the knob diameters (no Brits smirking please!) -- this is a knurled surface, not precision machining. The Leica and the Photo Equip (formerly GMP) crank should fit most old M cameras as well as the MP, unless yours is one with significant sample variation. You must try it and find out for yourself!

ben z Posted January 17, 2005 Share Posted January 17, 2005 I'm not sure how much less elegant it would be, designed so the setscrew doesn't have to dig into the knob. Maybe you're right, because as you say, it does work. Or, perhaps it's because a threaded lateral hole and splitting the ring would be more costly to machine than just a transverse threaded hole, thus cutting into profits.

jason_b. Posted January 17, 2005 Author Share Posted January 17, 2005 Could the clearance problems be from all that black paint? How about the Chrome MP's? Still problems? Link to comment Share on other sites More sharing options...
emanuel_lowi1 Posted January 17, 2005 Share Posted January 17, 2005 I suspect that it's because the CNC machined MP top plates are thicker (considerably) than the old Wetzlar top plates. Link to comment Share on other sites More sharing options...
andrew1 Posted January 19, 2005 Share Posted January 19, 2005 I have one that fits fine on the old M3 I inherited just fine. unfortunately, it got jammed on another M3, one bought second hand here. upon closer inspection, I see this "new" one seems to have had a couple of parts replaced with MP parts. the rewind lever is the new, shorter M4-MP style, and my Wasserman crank got stuck on the rewind knob, which had clearly been replaced. (maybe some other bits too, but the camera works beautifully, and I'm happy with the deal I got an a great shooter) anyway, evidence indicates a difference in either dimensions ( or tolerance?) so I suggest you get a rewind lever specific for the MP for M2-3 knobs. (heh, heh...he said "knobs"...) Link to comment Share on other sites More sharing options...
