Angled milk crate rack prototype

[Crab107]

So heres what im working on for my milk crate racks. Its remedial or trivial at best but its what i can do for now until i get more advanced. Each rack has a particle board base secured with lock tite powergrab. Each tube is secured to the base and ech tube is glued to the next. Ive 6 put screws in each side of the milk crates to secure firing wires..luckily the tubes have just enough play to work the firing wire in between so theres no flight path obstruction. Im not sure about the angle yet. Ill have to fire them to make sure the angle isnt to flat.

Ive got a buddy that works in a cabinet shop tht will help me make a base that i can just set the racks on that will give a set up as you see in the pics..im open for critique advice
