I started off the weekend prepping for the Radions to arrive.  I only have one right now to build and design from.  The rest are on order.  I built a wood jig to create some acrylic mounts off of.  I trimmed all of the mounts to fit that jig.
I made 8 mounts.  4 over the display and 2 each over 2 frag tanks.  I'm only mounting lights over a single frag tank for now.  It will be a while before I need either of the frag tanks.  Obviously.  But, it's easier to build the mounts now while I already have everything set up.
I mounted the brackets to 8020 rails and then mounted those rails to the hood.
The final picture is the back end.  I'm using cable carrier drag chain 2" x 1" like you might on a CNC.  All of the power and control cabling will run through that to protect them while the hood moves in and out.
