I'm sorry Richard. My error in inadvertently sending it to the list. I undoubtedly erred in referring to the booster spring because all of my other Rollei's have used them for the highest speed.I omitted mentioning that my shutter tester indicates that the times for 1/250 and 1/500
are the same. Don----- Original Message ----- From: "Richard Knoppow" <dickburk@xxxxxxxxxxxxx>

Don, it would be better to communicate with Harry directly rather than on the list. BTW, I wonder about the booster spring for the F. I am not sure the late Compur shutters had them. My 2.8E does not, just the main spring but its a quite different design from the earlier models. I wonder what the symptoms are. Note that in the shutters with boosters you can feel the tension increase as you move the speed dial to 1/500th from any slower speed. On the later type Compurs you can't feel anything because all the tensioning is done when the shutter is cocked. The later shutters can also be changed in speed at will whether or not they are cocked. The earlier shutters should be set before cocking. This is especially true of 1/500th because forcing the speed cam to that setting can push the end of the booster spring under the cam jamming the shutter. Also, the increased force on the speed ring increases the wear on it. Its safe to move the speed dial from 1/500th to a slower speed while its cocked if you must but its not good to do it often. -- Richard Knoppow Los Angeles, CA, USA dickburk@xxxxxxxxxxxxx --- Rollei List - Post to rollei_list@xxxxxxxxxxxxx - Subscribe at rollei_list-request@xxxxxxxxxxxxx with 'subscribe' in the subject field OR by logging into www.freelists.org - Unsubscribe at rollei_list-request@xxxxxxxxxxxxx with 'unsubscribe' in the subject field OR by logging into www.freelists.org - Online, searchable archives are available at //www.freelists.org/archives/rollei_list
