M6 and lla
This Contax lla arrived a week ago from the USA, dead on arrival other than very slow speed firing and a very rattly and stiff rangefinder assembly. With the help of advice and pictures posted by you guys it now fires perkily on all speeds, the self timer cycles and the viewfinder is sparkling clean. The focusing is silky smooth, the rangefinder operates and is surprisingly accurate proven by the first roll of HP5 I developed yesterday. Exposures are not bad when the shutter works, appearing 1/2 stop over the marked value. 1 sec is 1.5 sec etc.
Problems remain as follows: The shutter blanks out on 1/250 upwards. The blinds travel at inconsistent speed on one of the slow speeds, the self timer is weak and requires further cleaning. I did not pay enough attention to the gears under the chassis - shutter, bevel gears, shafts and wind on train. I think I will look much more closely at this area once I have it stripped down again.
The wind on is smooth but notchy and I guess requires some adjustment to take up slack or maybe just feed some lubricant into it.
A big thanks to all of you who post, selflessly, your experience and pictures, these have been invaluable in this project.
Update 20th January 2014
Now fully restored with the exception of the self timer. Acurate speeds including 1/1250, accurate focus and sparkly viewfinder. A tribute to Zeiss engineering that this camera really only needed a thorough clean and minor adjustments to bring it back to life 60 years on. It is a joy to use.
Further update February 2014
After a thorough ultrasonic clean and re-lube the self timer cycles correctly and fires the shutter, wind on is smooth an all speeds are good enough, wow!
