Just a hint, this is a basic wood kit so don't be afraid to experiment and modify it to fit your needs. If you come up with something cool, post it, maybe I'll incorporate it. For me I wanted to make it easier to adjust the height of the stand quickly, so locked the nut on the lower half with a loose fit and gooped around the washer to keep it in place. I used thick CA and goop to lock the washer and nut together on top, then I got a 3/8" threaded stud handle from McMaster Carr and now it is one handle and 1/4 turn from loose to tight to rapidly adjust the height.
This is why I am purposely leaving out hardware (and to keep it simple and as cheap as possible) so it can be modified to suit your needs and ideas!!
