chris_burck1 Posted June 8, 2014 Share Posted June 8, 2014 I came into an old Process Velostigmat, still attached to it's prism and in very clean condition all around. Only problem is, I'm stumped on how to get the lens off the mounting plate that it's screwed into (I was able to separate the mounting plate from the rest of the prism enclosure by loosening some screws). I very sparingly applied some penetrating oil to the threads, but after 24 hrs it continues to stubbornly resist my efforts (and trust me, I'm using plenty of elbow grease!). I *could* use the lens as is. However, I had this crazy notion of adapting the prism to my 6x9 press camera (or possibly my 4x5), so I kinda need to get that plate back onto the prism enclosure. Not to mention that general handling would be easier without that thing hanging off the end of the lens. Anybody got any ideas? Is it just a matter of giving the oil more time? Or is there something else going on here, like maybe they used some sort of thread locker? Any help would be appreciated. Link to comment Share on other sites More sharing options...

jose_angel Posted June 10, 2014 Share Posted June 10, 2014 <p>Cannot figure the thing (a picture will help), but I have a couple ideas:<br> 1. Heat or cold. Applying heat to certain areas use to help removing some things (dilatation).<br> 2. If you finally give up the plate, just cut it with a Dremel or so. The rest will remain intact.</p> Link to comment Share on other sites More sharing options...

chris_burck1 Posted June 19, 2014 Author Share Posted June 19, 2014 Thanks for the replies, guys. Unfortunately, I'm on mobile for the time being, which complicates matters somewhat WRT to posting pics. For that matter, even when on desktop, posting pics to threads like this is sometimes challenging for me. Perhaps I overcomplicate things. I had already considered the hot/cold trick, and discounted it on account of being too complicated given the size and configuration of the assembly. But, that said, I got the pieces separated the other day. Just a matter of letting the penetrating oil do it's work, I guess. Link to comment Share on other sites More sharing options...
