Managed to get the build 90% test fit.
First, assemble the frame: (4x wood screws)
It helps to pre-screw the bolts, as the milled holes are tight (4x 2" bolts, 2x 2.5" bolts, 10x washers, 6x nuts):
Use a 2.5" long bolt on the back side to attach the bungee to:
Inside view:
So far:
Next step: insert bearings into the swing arms (16x bearings, both sides) and latch for bungee (2x 2" bolt, 2x washer, 2x nut):
Note: I was able to easily insert the bearings into one side of each piece, but was unable to insert bearings into the other side. I'll need to bore out each hole by a minuscule amount. No amount of hammering would allow the bearings to go in. These holes should be increased by maybe 1-2mm in the CNC plans.
Attach swing arms to frame (4x 2" bolt, 8x washer, 4x nut):
Note: I did not use a washer on the outside fittings as the washers I have are as large as the bearings and negate their flexibility. When tightening, allow some wiggle room unless your bearings are properly sized. I'll probably be replacing the washers with different sizes.
If I could go back in time, I would have drilled these holes before I painted (attaching the swing arm to the front lift handle):
Note: Now is an opportune time to attach the wood for the bike handle. Once the platen frame is on, it's next to impossible to fit a screwdriver in a position to attach it. I did not do this step, and will reconsider once I tear down and rebuild with more paint, a few extra parts, and some daylight.
If I could go back in time, I would have drilled these holes also. Note that the wood has split; I drilled slightly thicker than the milled holes in the frame to account for threading, but it was not enough. This is to attach the platen frame to the bottom frame (4x 2" bolts, 4x nuts, missing 4x washers):
And here's where we're at:
Note that the attachment for the bike handle is not on the lift arm. See note above.
If I could go back in time, I would have drilled the four holes to attach the light frame to the platen frame before I painted (4x wood screws):
Note that I ran out of paint and only got one side done. This does show up in the reflection, and must be remedied.
This is the point where I attached the cradle frame to the unit (4x 2" bolts, 4x nuts, 4x washers, 10x wood screws, 4x bearings)
Note: 6x wood screws attach the cradle together, 3 per side. 4x wood screws attach the bearings to the sliding cradle. The bolts attach the lift arms to the cradle, and once again I didn't use a washer on the outside due to size. That will be remedied with another trip to the hardware store. See also the incomplete paint job.
Next up: throw in the lights and the glass(2x 5.5" shrouds, 2x 75w halogens, 2x 11X13.75" panes of glas):
Note: I held the glass in place with the longest bungee in the assortment as a temporary measure. I'll be experimenting further. The bungees are functional, but prevent the cradle from lifting all the way up to the platen to flatten the pages. Also, I think the glass is going to slice them in half.
Finally, attach bungees for tension (2x 18" bungee cords, 2x 2" bolts, 4x nuts, missing 4x washers):
Note: this kit is still incomplete. I need the bike parts to assemble the trigger mechanism, two bolts of the right size to attach the cameras, some smaller diameter washers, two pullies, and some paint. I'll be updating as I go!
