Looks great!!

SUCCESS!!
Turns out the Banding issue was much more related to the size of the exposure Slit than the gears. While I did change to helical gears which improved banding a bit, some deep-dive research...

Nice!

Me printer just doesn’t have the resolution for fine teeth. I reprinted the gears as helical, which certainly improved the banding but it is still present. Perhaps if I had a higher res resin...

More test shots this afternoon. Improved focus. Banding is still present. Better gears on the way.
Got some light leak to track and fix. But most importantly, I must have the gear ratios close...

Thanks! It was really a “I wonder if I could…” kind of project.
I’m currently using 14x36in x-ray film. It makes one shot spools. I also have a 6 in roll of Ilford multigrade on the way for paper...

A few more details...

Hi all 3-D printing LFers out there - just posted version 1.0 of a LF rotating panorama (Cirkut) camera I'm working on...

Hi all,
About a month ago I started musing on the feasibility of building a Cirkut-type rotating panoramic camera using 3D printed parts. After a few weeks of research, designing and printing the...

Nice!
Cobbled but working is a win!

I haven't done any exposure testing of the Royal blue vs Pink. If any is lost, I haven't noticed in use. With this latest build I'm getting similar times with the Green vs Pink channel. a typical...

I've built / rebuilt a DIY LED 5x7 head for my Durst several times now.
First was with standard RGB LED Strip lights - worked as proof of concept, but the Blue isn't the right wavelength for VC...

looks good!
I'll have to attempt a 5x7 soon...

drop me an email address in DM and I'll send you the .stl files

I have an Ender 3 v2 that I got for less than $200 about 9 months ago. I had no 3d experience before then.
In that short time, I've learned simple CAD (TinkerCAD) and with that have designed and...

This is a plate holder. I wanted to avoid hinges/flaps. But after doing this, I might try it.
I get the garolite from McMaster-Carr. Last batch I got was 1/16" x 12"x24" .

Here's my version of 3-D plate holder - this a 5x7 I designed and printed this summer. I based it off my 1903 wooden holders. Parts are printed to mimic the slotted wood, including joinery that...

Here’s my solution for most barrel lens - almost as simple but a bit more controllable than the Galli shutter. Black matte board with a slit cut in the middle. With practice you can get fairly...

Very nice - thanks for documenting!

Nice!

Totally reasonable - I have an 8x10 B&J with a setup you describe. I built a lensboard / box with Packard Shutter mounted in the back to use a nice petzval. Air hose goes though the Lensboard - no...

Press on series filter step-up adapters - to - any normal mm filter size have always been hard to find in my experience. Often it's a 2 step process - for example Series VI to 'MM I don't want', then...

I Use construction type foil-faced foam insulation boards in the window of my darkroom. Cheap easy to find at hardware stores and home centers and very easy to cut. Cut it 1/2 in. larger than the...

I use the foil backed pink insulation foam panels in the window of my darkroom. The foam is easy to cut, deforms easy to mold itself around minor bumps. The foil makes it 100% lightproof. It’s dirt...

I made a decent 11x14 washer from 1/4" plexi with a less than professional grade table saw. 2 chambers each able to hold 4 prints comfortably with dividers, water from first cascades into the next. ...

You can get decent digital milligram scales from major online retail site for less than $50
Mine came with a calibration weight too.

Graduation weekend for my son. Will have to keep you in suspence till next week.
Mostly McMaster Carr stuff

WOW that is quite a cannon indeed!

My ULF scissor lift ver 2.0 is making progress - I ordered a 1/2 acme/jack screw. It's a 36 in. rod, and it was delivered in an ** 8 ft ** cardboard tube.

Nicely done!
I like the eye-bolt tie-downs.

Indeed - those wheels look great!
I think with the success of the scissor lift, I may move on to ver 2.0 rapidly with the addition of some larger wheels. Love the rickshaw concept!
And thanks to...

Last weekend I joined the world of ULF with my latest project. I was given this copy camera body over 20 years ago from a customer back in my camera sales days - It has moved houses with me and sat...

Love it - simple and elegant solution

Indeed. My early version only had mixing chamber + frosted plexi and that was a bit hot in the center. But adding the second layer of plexi with an inch or so gap between evened things out pretty...

Thanks!
I enjoy your many DIY posts. JB indeed has many good things on his site too - it was a great proof-of-concept jumping off point for this project.

As I've been dabbling with handmade emulsions and alt processes, I have recently been longing for standardized exposure for my plates as I test different formulas and variables. I needed a...

well done!

Following!
I have a 14x14 copy camera i'll be working on this summer and need a transport system for it
