My first camera build. Nearly 97% of the camera on bench. Fine focus TBD.

Black aluminum from https://8020.net/

Custom Bellows UK (http://www.custombellows.co.uk/). Bellows removeable for use on next iteration. Or Not.

NOS 4"ID Packard with factory sync, bought here, permanently installed behind 8X8" SC Deardorff style lensboard frame.

Orphan 11x14 GG frame.

Russian Birch plywood, cost $2 at Menards and is perfectly flat.

GG blank glass from Home Depot. $3 DIY grind.

Camera will be modular and easily changed with hex key.

Designed to use Ektar 10"WA (http://www.largeformatphotography.info/classic-experts.html) to 790 mm Wolliston (http://www.re-inventedphotoequip.com/ULF%20Lens.html) with Macro.

Wood rulers will be integral part of the camera as rear bellows frames that slide into the long aluminum channel.

Code named 'Tinker Camera' as it is mutable, base components may be used with larger formats. I choose 11x14 as I already have film holders.

'Mistakes' are evident, however prefer operational before redesign.

Primary goal was to use off the shelf parts and as little power tool as possible. While cutting wood could be done with hand saw, I will use handheld power tools.

Called Location camera as opposed to Field or Studio. It is sized to fit in Pali's suggested bag (http://www.bhphotovideo.com/c/product/1126498-REG/gator_cases_g_mixerbag_2519_padded_nylon_mixer_equipment.html).

Weight 20 Lbs reducible by refinement.

Looks like things are off to a great start! Looking forward to watching your build Randy and please make sure to post pictures of your progress.

You and I have the same exact ground glass :)

Thanks guys. Tonight I will tap 1/4-20 threads in all the square stock.

A sit down job while watching a movie.

Maybe have time for grinding the GG, I am going to try Peter's way with finer grit than I have been using.

The issue for me is, many here say to skip grit size step down and use the final grit from the beginning. However William Bell, telescope glass grinder and my grit supplier says to use multiple steps.

Multiple steps...or with that grit it'll take a long time.

Summer here and I am outside riding. Either bicycle or motorbike. I hate cars but love riding while I still can...

I will get to it hopefully soon.

Glad to hear that you are enjoying the weather. It's the same here in MD and we finally got decent sun after a long month of constant rain.
