Radio go box Part 1

So, a couple of months ago I was approached by VA6SDM to spec and then asked to put together a radio kit.  It is referred to as many things as a radio go kit, radio go box, or a slip seat box.  So this is the equipment that has been put into it.

TM-D710A (dual band radio)

TS 480SAT (Multi-band HF radio)
LDG KT-100 (antenna autotunner)
Rigblaster PNP
Rigrunner RR-4004USB
Rigblaster PG-40S Super PWRgate
PWRBrite
Power Supply SS-30DV (by PowerWerx)

I had originally thought that I would put the unit into a tool box or into a road case (the ones that bands  or DJ's use), but due to the lack of fabrication tools I was extremely limited to what I could case the unit in.  The radio operator that will get this will likely not use it too frequently so one of my design considerations was to have everything as operationally ready as possible. 

One of the problems that I had with casing a kit like this into a tool box is that the rigrunner gets buried in underneath all of the other components and that adding a unit is not really easy, or accessing a blown fuse will take a lot of time.  Or accessing the power supply main switch without removing the main plate and creating a panel for it.  The other issue that was of real concern was that of cooling.  If I started cramming in all of those devices into a small space I would be limiting air circulation so I would have to add some active cooling devices. 

I decided that I would build a small cabinet out of wood.  I am very familiar with wood cabinetry or joinery.  I received the highest mark in CTS 30 or Grade 12 shop class with the dresser that I built for myself.  Now this cabinet is nowhere to the same quality as that as it has been a few years and I don't have a fully equipped shop to build it in.  I will post my sketches that I used to plan my cabinet as well as estimate my material. 

Currently I am placing the equipment into the cabinet, which is a little difficult because I did not mount the brackets in place before I assembled the cabinet so I have to put all the screws in place with a stubby ratchet screwdriver. 
 
The last installation issue is that of mounting the power supply and the autotuner into the box so that the do not move.  I have thought about using some All Round Steel Strapping, but I do not want to scratch up the devices.  My wife suggested I use some nyon straps, which is likely what I will use, but I am still open to options at the moment.
 
Well, I well get back to assembly and be back later with pictures and an updated.
