    Colin, that has got to be the most beautifully done "home made camera" I've seen. Truly well thought out and your workmanship is fantastic. Really enjoyed your log about it. Well done!

    Colin,

    That looks like a fine piece of craftsmanship. Looking forward to many more beautiful photographs taken with it.

    Beautiful camera Colin. I'm way impressed and enjoyed your blog on building it.

    Thanks guys, appreciate the comments. I'm glad the blog came across ok. Spending that much time on one thing, well, I was afraid my lunacy might have started showing through. I really enjoy starting such projects but wow am I glad when they're done!

    We would probably see that as totally normal!

    I know exactly what you mean about walking in and out of a hardware store and not getting the part needed for a project. Your back spring mechanism is a great design, I found the left and right hand wound springs but haven't figured out the sizing yet, I wonder if the old camera manufactures measured in inch pounds with tools or just developed them in time by trial and error.

    Yes, sizing is tricky for the springs. I used trial and error myself when I first came up with it several cameras ago. It's hard to get a significant amount of torque without getting really large springs (like those 4 inch coils on graflock backs) so I had to compromise a little. My holders are very flat so I don't really need the mousetrap-like tension (and no need for a bail back either). If it's any help, the part number of the springs I used from McMaster Carr is 9271K42. If you need really strong tension, the traditional flat leaf spring is probably most efficient design.
