Camera Crane Dimensions

I have had a few requests for plans to make my Go-Pro Camera Crane.  So here are a few images with simple dimensions:

The thicknesses are determined by what plywood you can source and the thicknesses of the Aluminium tubes. Thickness is also determined by the type of bearing you source.  I've used inline skate bearings bought from Amazon for a very reasonable price.  They are countersunk into the plywood and accept an 8mm dia steel rod well.  To anyone hoping to build one of these, I wish you success.
