Subject: [rollei_list] Back on the list / OT
Hi Everyone,
I am back on the list after a trip to Liberia in November
and for a
while too much to do to sign back in earlier.
Just purchased another nice Contessa folder (Synchro-Compur)
and a
Practica FX with shutter problems, but a WL fiinder with
unique slide-
in prism viewer and 2 lenses, a Schacht Ulm Travegon
3.5/35mm and a
Steinheil München Culminar 4.5/135mm. The Culminar is
finished in
gorgeous matte chrome. Looks very much like a my Leitz Elmar
4/135mm
and, like that lens, it has a removable lens head, albeit
with a
different thread then the Elmar/Hektor lens heads (Marc?).
Both
lenses are in "M42" (Contax S, Practica, Asahi P. thread
mount).
The Culminar's focussing helicoid is very stiff. Anyone
know if
that's easy to fix? It would be a nice lens to use on an AP
Spotmatic
etc.

The lubricant in the focusing helix has hardened up.
I've found that standard grease down't work well, the stuff
used seems to have a particular viscosity so that it has
some drag. I don't know what the right grease is. A similar
grease is used on the focusing cams of the Rolleiflex.
I would not try to get solvent into the helix to free
it both because it may make it_too_ free and because it may
work its way into the lens cells. I don't know who repairs
these things.
