I've missed a few of these posts, and have a few comments.
First off, nice builds! A couple things I really like. The hamster on the side of the wheel, that made me laugh. I may have to do that.
I like the nut/washer combo to help keep things square.
Mounting the spring to the table is different, I haven't seen or thought of that before. I like it.
That's a very spiff vfd! It almost makes me want to set on up that way, too.
