Thanks for posting those videos, Charles. It's too bad that all the other video links in this tread got deactivated. That's sort of dissuaded me from posting updates.
I'm still lurking...just not much going on. My Powell has been sitting on the shelf in my garage for a long time waiting for me to do something with it but, I don't have the resources to rebuild it. I've been watching youtube and occasionally posting there more...I'd rather be making something and post videos of it, though.
