Need a strong workbench

I've made space...now I think about to make a workbench, but not like I had them bevor, this time I wanted it...strong and solid...a table which would not fallen apart so far...
For this I provide some wood balks ^^

See here soon how it goes on witch the workbench...and what happen with the Yamaha xs400 frame
