Today I spent some time running around town looking for some steel to make my drag wire block drilling jig. I couldn’t find exactly what I was looking for so I ended up just making it out 1″x1″ square tubing slid onto 3/4″x3/4″ 6 ft square tubing. I tacked 1/4″ nuts on to two adjacent sides so that the the tube would ride part of the guide tube. I then welded on 1-1/4″ still strip with some spare steel tube that had 3/16″ ID. I match welded them together then cut the guide tube in half so they would be exactly aligned. I tried it on a mock piece and it worked perfectly.
I also measured each drag wire block for centerline and then marked 1/8″ up and down depending on where it was located. I glued those in place. I also glued the extra piece of cove former on the most inboard compression rib at the start of the aileron bay.
