Paulaberliner, Didn’t see your last post, so ignore most of my post.

Finding OEM knobs, is going to be difficult. If you are dead set that, I’d check with KHB Photografix (long shot), put an WTB ad here and on Photrio, and start watching EBay. As far as aftermarket...

Long retired from jumping, definitely miss it and sure miss the friends I lost. It’s an unforgiving sport, especially B.A.S.E.

I built a new base board a few years ago for and enlarger at Harvey Milk Photo Center. I took two sheets of 1/2” CDX plywood and laminated the together with yellow carpenters glue. If I recall I...

Nice one Austin, but I seeing wild creatures rearing their ugly heads.

We made it to the show yesterday and thoroughly enjoyed it. Jim, it was great to see your work displayed in such a nice space and I especially enjoyed seeing the portraits of you and June.

Roger

Jim, congratulations, I’m sure it will be a great show. I can’t join you on Saturday but it looks like the show will be up through April 10th so we might get a chance to see it. We’ll be in Oregon...

Congratulations, the show looks great, we are headed to Oregon, so who knows, a little side trip might be in order.

Roger

Jim, any reason you can’t swap the scales on the two shutters? The shutter on the 150 looks beat to heck, so I’d be inclined to swap the shutters, you just need to make sure you get the spacing...

Wow, that sure a beauty.

Roger

Andy, the video is private, I can’t view it.

Sounds like you may be missing the spacer ring, check out this link. https://skgrimes.com/product/retaining-ring-copal-3/ . I also add that’s it worth checking with SK Grimes on the aperture scale,...

Tuco, you’re knocking them out of the park, especially the sea stacks.

Roger

Well, considering that ginger bread is an approved building material used in home construction, it should make a fine lens board. ��

Roger

Bryan, this on is outstanding, you framed it perfectly.

Roger

Would it help to sensitive the board with potassium dichromate and expose it to UV?

Roger

Most retaining rings have an inner collar that fits into the hole in the lens board. Just measure the O.D. of the collar and add a few thousands for clearance.

Roger

Plus you can throw your dark cloth over the bellows for extra assurance.

Roger

I just measured a Eastman Kodak 2D 5x7 lens board and the exterior measures 4.495” square, 1/8” thick ant the interior measures 4.121”, 0.141” thick, so very close to your Gandolfi board and would...

Very nicely done.

Roger

I would definitely check my local hardware store, but if they didn’t have what I wanted I’d try McMaster Carr.

That’s where I bought mine. I did a quick check and didn’t see any currently listed, so you would need to contact him.

Another source would be S.K. Grimes....

Aka foamed PVC board.

Roger

Paul, both very nice, I really enjoy this type of forest scene.

Roger

“Above the Gorge” nice work here, great to see what one can do with Delta 3200.

Roger

Thanks!

What’s the red hose? Fifty feet is impressive.

I always mount to the same cotton rag board that I’m cutting the window mat out of and then use acid free foam core for a backing board. I generally have a reveal between the window and the print so...

Good point on the water bath, that’s how I’ve always used the BTZS tubes. It’s really hard to beat the water bath for even development.

Roger

Those tubes are manufactured and sold through “The View Camera Store”, although they show out of stock right now. Here a link to a thread on 5x8 development, see post #9 for an example of 5x7 tubes I...

Nice one Bryan!!! Looks like a big shiny Christmas ball.

Nice one Paul, love the shallow depth of field and how that lens renders the out of focus areas. Really makes the subject stand out. Also love persimmons, just got a box from my friends tree.

Austin, that Volvo shot is hilarious.
