Hi James, (I've enjoyed your build log) Why box? Well, my thinking is that in the right circumstances box is stronger than plate or angle, especially if you are expecting the loading to be in multiple directions.

Square section is very efficient shape for this multiple-axis loading as it has uniform geometric and thus uniform strength characteristics along two or more cross-sectional axes.

Having said that, a hexagonal profile made from welded triangular shapes would no doubt be even better :lol: but "£ for lb", box is good value.

This view may well be modified after practical testing! :naughty:
