Time to wheel a barrow back .......... this design is from the mind of Peter Read ...... i have only copied what I have seen in his website images .....
A couple of custom touches that I have added are the powder coating of the stainless steel RHS tube, brass screws, and end caps for the tubing....

Wherever the bolts went through the tubing, a Delrin insert was placed inside the tube to prevent it being deformed when tightened. (see one in a pic ..)
