re: Worktop Workbench

Great job B_UKy... while my "mini workbench" is totally different, the concept/purpose is similar. 

Contrary to what pottzy said, I use mine extensively, if only to move the work platform around the workshop/hose. 
You'll probably get hooked on the concept and expand/redesign for various formats.  It's easier to whip out a few dedicated formats and mount on the workbench than try to change/customise the workbench.  You just need to get your preferred take, for mounting on surfaces...
I use the TSO loc-dogs and the Rockler/(generic) Universal Fence Clamps.
