Final part of the mechanical construction complete with the stabilization of the Y-axis.

Final part of the mechanical construction complete with the stabilization of the Y-axis. This is done by tying the bottom carriage of the old scanner with its associated belt movement to the wood assembly. This is done with a 1/4" threaded rod cut in half and secured to the outer 2x4 and the metal carriage in two places. This not only serves to stabilize the bottom but the double-nut assembly allows fine tuning later to ensure that the rails of the Y-axis travel in a direction perpendicular to the travel of the X-axis. Why not use 1/4" bolts instead and not an assortment of washers and nuts? Well that is what I had in my coffee can of stuff, so that what was used. No reason to buy something if you do not have to!

Now comes the real tough part, at least for me, assembling the electronics. Have what I need, purchased from MakerFarm, now just have to figure out how to assemble it.
