Step 3: Riveting stuff
[pic 2] is the box so far, now for the corner pieces. Elcom part 1064 from this page are the ones I used. I put the "feet" part of them at the rear of the case, so when the handle is at the top, it's sitting on the feet.
Hold a corner onto the case and drill the holes out [pic 3]. I didn't use a pilot hole, the corner piece held the drill bit in place. IMPORTANT: For the holes that are going through the locking extrusion, make sure you only drill through one side of the extrusion and not all the way through! The rivet will grip just fine through one side only.
Rivet on all the corners and step back and admire your work. Looking very sharp indeed!!
