Storms were gone after noon today, so I got back to work.

Picking up where I left off yesterday I fired it up with the plate with two aluminum angles on it. After twiddling with the settings a bit I started to pull real nice fibers. But they still weren't going from one angle to the other. It took me a bit to see why. Turns out some of they were going all the way across, but they sagged in the middle and touched in the center, where they stuck for good.

I figured that out by placing some blue painters tape sticky side up all across the table. By getting them to stick where they hit I could trace them all the way across. I don't remember them doing that a few weeks ago when I played with making parallel fibers. The only difference is last time the angles were just placed on the normal flat stainless steel plate and this time the plate is non-conductive. That's pure speculation at this point, but I guess there is one way it may make sense. That is the conductive plate is at the same electrical potential as the angles, where the this plate wouldn't be. I do know that the fibers hold the charge they are given as they are being pulled and tend to push each other away after they land.

Well, I'll explore that in a bit.

Right now I thought I'd show you some decent length fibers as they are being pulled and laid down. Check out this video:

Sorry about the light moving around so much. It's hard to get a flashlight to hit at just the right angle, and they are so thin they're hard to spot otherwise.

It lays them down at a pretty good rate, don't you think?

Oh, and that's real time, too. It tends to put some fibers down on one angle for a while, then switch to the other for a bit.

Anyway, it's been a long day and I have a Doctors appointment in the morning, so I'll get the pictures up for you in the morning. You'll see they are nicely parallel, which was the entire reason for doing it this way. Collecting them and keeping them parallel when they touch down in the center is a challenge, but nothing that can't be worked out.
