I built mine around a 1200 x 600mm chipboard shelf - used 90x35 pine as framing - initially started as somewhere to hold solar panels now it holds camping gear , tools , toys etc etc - have two mobile work benched one with drawer for small tools - wire strippers etc - one has my Ryobi chargers mounted permanently with an Aldi powerboard with twin LED lights ... If I can tidy it up a bit I'll post a pic or two ... M
