@Dannydefe: I am going to make it as tall as possible. You will need about 1" on each side for the thread clamp and the coupler. I am going to have the coupler double as the bottom thread clamp. Looks awesome BTW.
I got my screws and nuts today and any worries I had about friction, backlash, straightness, etc have gone away. They will be perfect in my opinion.
I am going to add a bottom plate like you have. I will mill sockets for the steppers. I will remove two of the back screws of the stepper and replace them with longer ones so I can bolt throught the bottom board.
Additionally, I am going to get some cheap threaded rod to go through the middle of the PVC columns to make assembly super easy and make everythong very rigid.
