tadeyev Posted June 21, 2014 Share #41 Posted June 21, 2014 Advertisement (gone after registration) I am at a loss to understand how a rivet could rip out of a shutter curtain blade like that, particularly under conditions of normal use ... And I am at a loss why cheap rivets are being used in the first place.... Link to post Share on other sites More sharing options...

jaapv Posted June 21, 2014 Share #42 Posted June 21, 2014 I have information on the price, but what type of fixation would you use? It is the very first time I have seen a ripped-out rivet on a shutter failure post as far as I am aware. Usually it is a shutter-blade salad. Link to post Share on other sites More sharing options...

Echo63 Posted June 21, 2014 Share #44 Posted June 21, 2014 And I am at a loss why cheap rivets are being used in the first place.... they aren't cheap rivets, the shutter mechanism is bought as a unit from Copal. I can't think of another low profile way of having a pivoting anchor point on a shutter blade. I have information on the price, but what type of fixation would you use?It is the very first time I have seen a ripped-out rivet on a shutter failure post as far as I am aware. Usually it is a shutter-blade salad. this may have been caught early - before it became a "shutter blade salad" as for the "Just in time" parts supply. when i was fixing cameras (Not Leicas), there was certain parts we were ordering 50 at a time, and it was not unusual to have 2-3 orders in, each having a bunch of those parts on it. our normal waiting time was around 3 weeks, although that blew out to 8 weeks over summer (christmas time) as many people were using and breaking their cameras around that time Link to post Share on other sites More sharing options...

They are from Copal....So therefore they cannot have problems? A rivet is not always a rivet. From the colour they appear to be aluminium and their edges have sheared. If a rivet can shear that easily it does not seem to be engineered for the long term, unless some other reason prevails here that I cannot fathom.

jaapv Posted June 21, 2014 Share #47 Posted June 21, 2014 Advertisement (gone after registration) They are from Copal....So therefore they cannot have problems?A rivet is not always a rivet. But a Copal shutter is always a Copal shutter, no matter what camera they are fitted to. If there were a desgn flaw by using these rivets, all camera forums would be full of it, instead of one solitary report here. Link to post Share on other sites More sharing options...
jaapv Posted June 21, 2014 Share #48 Posted June 21, 2014 The turn-around times in Europe are currently also 6-8 weeks... Leica has a capacity and spare parts problem in Wetzlar... Quite possible right now.. My last repair was a couple of months ago, just during the move to Wetzlar. Turnaround was quoted at three weeks and I got the lens back in two.

xrogers Posted June 21, 2014 Share #49 Posted June 21, 2014 Copal isn't perfect, but is also very likely the most experienced high-quality shutter maker left in the world. I'll take a Copal shutter any day. Copal does make shutters from different materials, and at different price points. Given the feature set of this shutter, it is unlikely to be cheap. It doesn't matter how good your devices and quality control are, failures happen. What defines good service is how the problems are handled. Link to post Share on other sites More sharing options...
bocaburger Posted June 21, 2014 Share #50 Posted June 21, 2014 When I take my Porsche in to the dealer for service for any reason, they give me a free loaner. So when they keep my car on average 3-4 days to do a 1-hr repair, I don't get aggravated and I don't complain. I don't have to be a professional race driver to get that service either, every buyer gets it. I think people who pay a hundred grand for a car or seven grand for a camera want, expect and frankly deserve a little covet from the manufacturer.

jdsheepdog Posted June 22, 2014 Share #51 Posted June 22, 2014 an enormous amount of force is exerted on the rivet and the blade on every shutter actuation. it's probably the most mechanically critical part of the camera manufactured with the smallest of tolerances in mind. sometimes, they are not met - ergo: this happens. I actually doubt that this much force is exerted on every shutter actuation. In fact, the only place I can see that much force coming from is the shutter actuation motor, and normally the shutter itself will not experience the load at any single point. The whole parts train will simply pivot and move, as designed. I suspect the shutter leaf has misaligned, jammed, and then the motor has tried to move the jammed leaf. Now the rivet would feel the full motor power, with enough force to tear out. Link to post Share on other sites More sharing options...
