TonyField Posted November 29, 2012 Share #1  Posted November 29, 2012 Advertisement (gone after registration) I have a couple of the old Leitz "double-ended bayonet" lens back caps that I like to use:  http://tphoto.myphotos.cc/pix/bayo.jpg  The only problem is that they are not sealed for dust. I was wondering what kind of solvent I might use to weld a separator plate. Acetone does not do the job.  Of course, I could get two normal bayonet caps and glue them together as well.  Any solvent suggestions? Link to post Share on other sites More sharing options...

moosehead Posted November 29, 2012 Share #2 Â Posted November 29, 2012 Try chloroform, dichloromethane if you can get your hands on it. Try one of the chemistry departments in your local university. Good luck, Gerry. Link to post Share on other sites More sharing options...
jaapv Posted November 29, 2012 Share #3 Â Posted November 29, 2012 Why don't just epoxy-glue two normal lenscaps back to back? Those old double ones are too shallow for wideangles anyway. Link to post Share on other sites More sharing options...

Â Too shallow to use for two wideangles. But they work fine for combining a 75/90/135 with a wideangle. However, I rarely use mine as the fit is too loose.

Â They are not perfectly flat... : surely possible along the slightly elevated diameters (which are 1mm wide, and flat) but can maybe result in a not so strong coupling.... (I had this idea of coupling a pair time ago, and renounced... but it could work, maybe). Link to post Share on other sites More sharing options...
jaapv Posted November 30, 2012 Share #6 Â Posted November 30, 2012 I've been doing this for years. Epoxy glue is filling. You need to roughen the surfaces a bit. Link to post Share on other sites More sharing options...
