So if I go with the 2x2x1/4 material, it should have an ID of roughly 1.5x1.5. I could print a part with a stub on it that would mate with the end of the rectangular tube. Maybe some sort of flange as well.
Cut the fiberglass and get them all equal length. Goop up the ends with epoxy and clamp it in a fixture. Maybe just drill a couple of holes in a chunk of plywood, put in some bolts, and do them all on the same fixture. Mount the bearings in the parts first and then run the bolts through the bearings while the glue sets up. Extra nuts and washers on the bolts = clamp.
They might not all be right. They would all be wrong the same way. Do the trick with keeping track of which end and surface is which. Mount them all so same end / same surface is in the same orientation. I suspect the net result is a hot end that is not quite straight up and down. The rest of it would be binding in the bearings, and a slightly odd number to enter in the python script that translates the gcode.
Sounds like a plan.
Now ... more design or off to bed ....
1) Which bearings to use on the hub / effector?
2) How much of the existing central part of the design can be used on a bigger machine?
3) Need to scale up all the screw related stuff for 1" screws.
4) Plywood is all gang drilled, so no need for fancy stuff there.
5) Need bearings for the 1" rod.
Just a few little things to take care of.
