I kind of realized I probably couldn't get these out of my basement. So, I only built half of each of these, but it's easy to scribble in a few new dimensions. I also wanted to run the verticals high to mount lights to, but scratched that to use less wood.
The 29/20L rack I built was more wobbly than I would like, it would be good to add some structure as Kulasik suggested.
I like your suggestion as well Marty.
I'll try to post more stuff as I go if it's helpful
