Here's a rather odd request...
I am in the middle of designing and assembling (I say assembling because I'm leaving the building of key components to those more skilled than me) a 7x17 camera. It will be similar to the 4x10 camera I currently used that was assembled using parts from ARCA-SWISS and Lotus. The design work is done and I have created a spreadsheet with the weights of the individual pieces/assemblies. However, the two pieces of data I lack are the weight of the bellows and back. At this point, I just have place holders for those two values and would like to get a more refined estimate of what my finished camera will weigh.
So, I seek the assistance of all you 7x17 shooters out there. If you have a 7x17 camera with an easily removable back and bellows, could you weigh those items (bellows including mounting frames and camera back - just the back, not the entire rear standard) and post the weights here I'd appreciate it. Also, please state which brand of camera you have and your maximum bellows length. I suspect different brands will vary a bit in weight and, of course, bellows weight is a function of length.
Also, while you have the back off of your camera, if you could measure the width and height, that would also be helpful. I'm currently using 20"x11" for the width and height of the back (based on a 7x17 Korona), but if there are any back designs out there that are more compact, I'd be interested in the details.
At this point, I suspect I'm in the 12 lb. plus/minus 1 lb. range. It's gotten a little heavier than originally planned, but I've added self-arresting geared rise and axis tilt to the front standard, as well as rear base tilt and swing to my original concept and I've beefed up the rear format frame to make it more rigid.
Thanks in advance for any data you can provide.
