Yesterday, went to thread the new tie rods - only to realize that the die stock [handle] is made for a 1" O.D. die, and I have a 3/4" die. Not even the manufacturer of this die appears to make a stock for this die - that's craziness, right there. I'll figure out where to find it or make a workaround yet!
Also, got the tip bows out, and realized that they look nigh-identical, but they're not. The angle of the half-moon piece on the end where it snugs into the tip of a noserib is specific to the right and left wings. Also, the little notches in the old spars are for wing bow support and clearance. Started to contemplate how best to make a template for said notches, when I picked up the little half-round file I'd been using to round corners on metal, and realized it fit perfectly in the notch at a 45 degree angle. Template, heck - this is file to fit.
Also, finally now know what the twisted tangle of aluminum tubing was for - it's to carry air pressure from the pitot tube on the jury strut to the airspeed indicator. I'm not sure I trust it enough to reinstall it; we'll deal with that today.
While it didn't feel like much progress, the butt ribs are now ready to go on the spars! A little more progress, every day.
