Since I had two sets of everything (controls), I simply used the 2nd set of shafts with the gears to extend the shaft out. I wasted the gear, but doing that expedited the job. There is another set of gears inboard that line up with the gear track in the extension.
John, like I said very nice job. Now the fun of 8x20 begins. You start to look for images to fit the format. It is a lot of fun and you will slow down, trust me.
Here's my 8x20 made from (2) Kodak D2's. One was an incomplete basket case. The other was in need of serious restoration.
I made a crate to haul it around in as well. It can hold (3) filmholders, extension rail, camera, extra lens(es) and a darkcloth and meter.
I made a strut to be part of the original tripod adapter. The strut keeps the base and the extension rail and front rail in a plane. No sagging. Important to me as a I have a 600mm Apo Ronar waiting to be adapted to a shutter.
Here's also a side view showing the complete assemble. You can see my cylindrical bellows support. It rolls as you focus in/out.
The back is really all I made. It's from Cuban Mahogany finished with tung oil.
The GG protector attachment point were built into the back.
The underside shots show the construction. All the D2 movements are preserved.
This outing was a trial run. I didn't even have 8x20 film, so I butted together (2) 8x10 sheets in the holders.

John, beautiful work here. Way to go with the "use what you got" approach. My compliments1

Here are some pics of my new project an Agfa Commercial View 8x10 that I am making into a 8x20 although I want to start with a 7x17 back. I have raised the Front standard to allow swing, the back came up to the same height and still gives access to the backs controls which is very handy indeed, I also want to add front tilt. I hope to make the bellows as per my 8x10 and will attempt my first a back and film holders, thats the reason I want to start with the 7x17! then when i am more confident add the 8x20 back and holders
If anyone one has advice on 7x17 Film-back and Dark-slide construction I would be most grateful
Thanks
Brian
Measure Twice, Cut Once!!! I have to make three before the sucker is right!!

Brian, nice work so far. It is a labor of love. You should PM my friend Dan Dozer about the back and holder questions. Dan has a nice book that he did on the building of his 8x20. We built ours at the same time and he documented the construction. The book he did is very helpful. He sent me the page on building the back and I got mine in perfect registration. For me it was measure 50 times and cut once! Dan built his holders but told me recently that due to consistent small light leaks he broke down and bought some holders.
I recently finished this 18"x24" camera. It's not pretty and my ability as a carpenter is, let's just say, pitiful. Built mostly with a mitre box and hand drill. I did use a circular saw for the rise/fall and focus slots. So far everything seems to work as planned but I won't know for certain until I convert the plate holder and stick some film in there. I built everything except the back and bellows and the back is horizontal only. I haven't weighed it yet but I think it's ~25 lbs.
Brian, and I thought I was a glutton for punishment! I built my 8x20 and 11x14 with hand tools in my apartment but this is amazing! Dude, you rock!!!! Nice to see what can be done with some thought and patience. Nice going!
Thanks Jim! I really am a glutton for punishment, after shooting 11x14 for a while I realized I needed a bigger negative. After looking at the ground (plexi)glass on this beast I felt like it was getting closer.:rolleyes:
Does anyone have a 30x36 back and bellows lying around?:rolleyes:
Brian, and I thought I was nuts! A 30 x 36! I know you are serious! You take the cake! Brian, I hope Dan can get you the info you need. Might also try Barry Young. He is a camera builder in the Pacific Northwest.
Don't remember if I posted the shot of me and my Walnut 11x14 and tripod yet so here goes.
