Homebrew PCBs

Chris, just noticed the new pictures and read the descriptions. 
Thanks! I wouldn't have guessed any of that stuff from the first 
picture. 

The extended downward-pull bar and the spring to return upward are 
great (and easy). Even if I try a vertical bar thing, I like those.

One other thing I was just thinking about wooden glides on pipes, if 
anyone ever has to do such a thing, is that maybe a pair of pipes 
would be the tightest fit and hold up much longer. If you could find 
two pipes that could telescope, one within the other, like for an old 
tripod stand, you could slice a segment out of the larger one and glue 
it into a hole in whatever you needed to slide, that way you'd get 
metal on metal (the paper theory just keeps on coming). I also do some 
fiberglass here. I could maybe just grease up and wrap the "pipe of 
choice" a few times to form a nice FG tube. I've had to do that 
sliding hole thing a couple times for stuff. I've also used a piece of 
thin aluminum pipe and cut a slit along it, so that it could stretch 
around a piece of it's same original diameter. Again, the wood holes 
did hold up just fine, and the sizes were all standard bit/pipe size.
