1- This will be on my top subbed builds.. and i've a friend that will love this build. and will follow as he is learning to do his blocks as well.
2- Now to my questions. Can we get a 3d Sketch of how this is planned to looks like

, and are you sure about the structural integrity of two curved aluminum bars ? will your shells if welded/bolted give enough for the skeleton to hold on to the weight of the components? i'm not questioning. i'm asking if you have had a kinda of a thought about it.
Great build.. will love seeing this finish.
