How much vertical clearance is there between the bottom of the cradle base and the table top when the carriage is all the way down?

Re: Self-Adjusting Spine Support
Thanks, Chief. Tried some new bits on the first prototype. Replaced springs with 3/16" bungee cords secured with cord locks. Gap adjustment is by nylon cord and another cord lock. Seems to work fine. Is this type of adjustment OK or do we really need screw knobs? This way is cheaper and lighter but maybe not as easy to adjust at least until you get used to it.

I like the quick and dirty cord locks, myself.

Re: Self-Adjusting Spine Support
Yes, I like the cord locks, too. The whole thing is very well-designed! I'll have to draw up a version to add to the scanner.

Glad you like it. Drop me a PM with your address and I'll send it to you for testing in a scanner.rob wrote:Yes, I like the cord locks, too. The whole thing is very well-designed! I'll have to draw up a version to add to the scanner.
