Built a scanner? Started to build a scanner? Record your progress here. Doesn't need to be a whole scanner - triggers and other parts are fine. Commercial scanners are fine too.

Just got the adjustable cradle finished. The idea for this stemmed off of Icantread's adjustable cradle. this one would most likely be easier to build since there is not groove routing needed and the moving parts are more simple, his is obviously much more elegant though.

cradle somewhat open to allow for a book with a larger spline (thickness).

I ment to write about not using such a fine thread. On mine it takes like 50 turns to go a 1/2in its kind of a pain. I think I'll just epoxy a crew in my handle so I can turn mine with a drill.

lol, mine just has a nut holding it in place, and the nut spins so well that I can give it a good spin and loosen it about a half inch at a time.

the upright sliders are very sloppy, I have an idea to make it work though. just need to cut some more boards.

did some more work today. Got the new sliders finished, uses two drawer sliders, side-ways sandwhiching the up and down sliding board that is attached to the platern. before there was just one slider and it was on the front edge instead of sideways.

This works VERY good so far! but only time will tell after scanning in a handful of books.

more pictures... the slider work great when lifted from the sides, but it does not work so good if you try and lift from the front of the book scanner, the platern tweaks at an angle. I plan on setting up a counterweight system that completely offsets the weight of the platern or a foot driven pulley system, not sure yet. I have even been thinking about a motor driven system that moves it up and down with a push of a button.

I am in need of some pulleys :( I am going to focus on the rest of the scanner and tackle this issue after thinking about it for a while.

here is the latest progress. I actually ended up not using the camera rails at all, the distance was great with the camera all the way lowest so I just directly attached it to the slider posts.

one camera is not attached, because I used it to take this picture :)

I've been thinking about your racking issues. Think about the way those drawer slides were made to be loaded -- they are designed to bear weight from the top, not from the side as you have them. I'm wondering if there's not a way you could reconfigure them (not that you would really want to, at this point) so they might work better. For example, if they were on the inside-facing edges of your columns, when you lift the platen, the natural tendency of the platen assembly to rack would be loading the slides the way they were intended to be loaded.

Sorry if this is unclear.

no i get what your saying, rotate the uprights 90 deg. but actually the main problem is not the slides, because the way I have it sandwhiched they actually hold up great! the problem is with the single bolt that attaches the slide arms to the patern, it swivels at that point.
