1/11: Micah showed me how to remove excess material from the collars and bundling tools that were printed recently. I did that and sanded them in the morning. I polished a bundle of sci-fis with 1000 grit paper.

One lesson from today is that I need to use a light touch with fine grits such as 5 micron and below. The fibers should not even squeak against the wheel. If you press them too hard, the fibers will smear and get a little sticky on the ends.
Another problem today is how to hold the fibers - how hard to press down on the bundling tray and how to twist them. It should be a gentle twist. I was twisting too hard.
I think that when you twist the fibers it is hard to reach some areas of the bundle with the sandpaper. Maybe some don't get touched at all. That seemed to be happening when I was polishing the sci-fis. One side was polished but the other was not when I was twisting the tray. I might have reached those fibers more readily by reversing the spin direction and the twist direction, but I did not want to do that because it would also change the direction of the striations.
