There is a lot of art and science in building strong steel structures like rollcages, but a few simple rules can make a big difference. The corners are generally weak points, and triangles are your friends. One way to beef up the corners of a ’cage is with corner gussets (little triangles), but most of us are not born knowing how to build good corner gussets. Sure, you can buy some, but these that we copied from our friend Rob Bonney at Rob Bonney Fabrication are relatively easy to make and add a ton of strength to our corners. We totally stole this design from Rob Bonney. He is probably not the first guy to use this design, but we know it must make sense if he uses it and he was lucky enough (read: unfortunate enough) to be our patsy for borrowing the idea. These corner gussets are pretty easy to make once you get the idea. Space here is limited, but we can show you more in this article’s online version at bit.ly/2N2a1tY.
