Thread Adapters

Are there readily-available thread adapters for putting a lens built
for a Copal/Compur #3 into, perhaps, an Ilex #4? (or whatever would be
the suitable version)

TIA,

Collin

Hi Collin, There are no off-the-shelf adaptors. Generally the lens
cells are mounted in tubes which form the adaptor to the shutter. The
treads must be right but also the apex spacing of the lenses must be
right. In general the adaptors must be custom made for the particular
lens and the shutter its desired to mount it in. Such work is done by
precision machinists like S.K. Grimes shop: http://www.skgrimes.com
If your lens is in a Copal or especially a Compur why put it into
an Ilex shutter, which is IMHO inferior to either. Compur shutters
especially are very rugged and can almost always be brought back to
new shutter performance by a skilled repair person.
