Thanks for the replies.   I tried the gloves and cleaning the rubber strap wrenches. No luck. I am a bit afraid of putting my flattener in the freezer.   I think I am going to send it to AP Monday.

You might try putting it  in the freezer. Slightly different alloys of the metals may free then up. If doesn’t work try heating slightly, maybe by setting in the sun.

Subject: [ap-gto] Threads stuck on an AP Field Flattener

 

 

I have an AP Field Flattener for my 155 and the threads are too tight to twist off.  I have the adapter for a DSLR stuck on the front.  I would normally not need to take it apart but I can hear the elements move inside and wanted to see if I could tighten them.

 

First, any suggestions for getting the threads loose?  I have some strap wrenches and they don't work.

 

Second, If I can eventually get the front adapter off, can I easily tighten the lens elements or should I send it back to AP?
