Separating process lens from prism?

[chris_burck1]

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.

BTW, my apologies if I've posted this question to the

wrong place. But it seemed to be the closest match. . . .

<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>

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.
