Thanks Mark & Kumar, very helpful both your comments.

I do not. But it looks like I'll be there soon for another visit because the front element will have to come off. I'll ask.
Sure. But the glueing of the front lens group into the shutter would seem entirely unnecessary and thus be an invention that was uncalled for. Additional work for no clear benefit. Hand tight will...
Yes, I found this after my debacle with this lens and am in touch with them to have one sent over. Looks decent.
Hi Mark, my post must’ve been confusing. sorry about that. Obviously the retaining ring attaches to the shutter. The rear lens group, like you write, screws into the shutter.
What I meant by the...
After having my new LF wide angle lens separated from its Linhof board, I now wonder about the front and rear lens spacing. (See my earlier post here; that post mentions it's a technika board but it...
Just before the holidays I picked up the lens from one of the two optical/mechanical specialists left round my neck of the woods. Turns out the ring had not been glued, just overtightened. But the...
That is a great suggestion, thanks.
EDIT: wait, does it have to be ATF of can it be any 10W mineral (i.e., non-synthetic) oil? Does the stuff they add to ATF make it more suitable as penetrating...
OK, so mine has not been glued. I am going to try with some WD-40.
Thank you for all these great suggestions. Last night I ordered a proper spanner wrench like the one @jim_jim suggested. If I replace the horizontal rods with much longer ones I’ll be able to exert...
I am hesitant to apply liquids to the thread as I'm worried it may enter the cells. Same for applying heat - not sure it's low risk enough for me to try. Maybe I should have a professional look at it.
Recently I bought a really nice Grandagon 155 f/6.3. It's on a Technika board and I want to move it to a Sinar board. The retaining ring fixing the lens to the board is so ridiculously tight that I...
My new (very old) Sinar P2 front bearer misses the depth of field scale barrel and fine focusing knob. I have a Sinar X rear bearer that has both the dof scale barrel and fine focus knob. I'd like to...
Here are pictures of the Sinar rig I’m using:

I’ll try to take some pictures for you. I recently bought the camera. It’s a bit of a motley collection of Sinar parts.
The flange in the first picture you posted looks great. That may be what I’m...
I'm looking at a Voigtländer Heliar 21cm f/4.5 for use with my Sinar F2 5x7 camera. The lens is a barrel type so it's not mounted in a shutter. Looks pretty straightforward. A bit like an SLR lens...
Thank you again, that should do it.
Thank you, that is very helpful.
You wrote that the lens is native to copal e.a. #1, whereas the information I have found states #0 (for example here). What I know comes from the internet and you...
Hi everyone,
I'm trying to figure out if it is possible to use this lens DB mounted for use with the Sinar auto aperture shutter. After some google research I found one old listing somewhere of a...
