Once all of the inner supports were made, it was time to tack them on. This was a little complicated, but here's how I decided to go about things. I needed to weld the squares at an angle identical to the bend in the vertical pieces (the long rods clamped to the jig). The angle is due to another bend that needs to be made once the pieces are in place.
I created an angled clamping block out of plywood and two strips of birch. One side rested flat on the jig, and the other was used to stabilize and clamp the square at the proper angle. It all makes sense in the upcoming posts, I promise.
Notice I have also added locator blocks on the jig to clamp the squares at the bottom. These are permanently fixed to the jig with glue and a nail gun.
