In order not to spoil it all as I did earlier by drilling the wrong face of the tubing in question, here I have turned the skids through ninety degrees. Now, and as indicated by the pointy rubber glove, we take our spare length and mark where the skid should meet the struts at each of the four corners of the airframe perimeter. The ballast is to keep everything steady in place of the more professional jig, which we're not into here.
