Eclair ACL CA-1 to Nikon conversion

[cinesota@yahoo.com]

Hi all,
Has anyone attempted the conversion of their original CA-1 mount to a 
Nikon mount?  I was looking at my increasingly obsolete CA-1 mount 
wondering what to do with it (besides selling it cheap on ebay) and it 
occurred to me, given the CA-1 has a flange focal depth of 48mm and 
Nikon is 46.5mm the conversion might be fairly simple. The internal 
brass sleeve can be removed by undoing 3 retaining screws. The brass 
sleeve is approximately 2mm thick so removing that leaves us at 46mm.  
Add the depth of the Nikon bayonet ring (the one I have is appoximately 
1mm thick) and you are pretty close. Some precision shaving of the mount 
might have to be done (1/2 a mm or so) to get us back to 46.5, but any 
good machine shop should be able to do it. The trickiest part looks to 
be the adding a locking pin for the Nikon mount and getting the Nikon 
ring dead center on the original ACL mount. Surprisingly the Nikon mount 
is approximately the same diameter as the ACL mount.

I purchased a Nikon-ACL mount about a year ago and upon studying it, it 
looks as if it once enjoyed life as a CA-1 mount and was converted at 
some point (albeit it is obviously a professional conversion).

Whadda ya guys think?
