Whilst the roll bar was off I took the chance to sort the strike plates (LHS & RHS). I used the normal 1/4" in the corners and then saw and files. Just takes time as it is very visible.
Then it was putting the rollbar back together and re-jigging it including all the bolts and screws.
The front attach plated between the hinged center and side rails have one location that is very close to the skin rivet. It looks like we will be able to use a -4 instead of a -3 and everything should work out.
I drilled the aft holes for the forward attach plate as per instructions (yes - I'm following the instructions again!)
The 1/8" spacer worked fine, lots of adjusting and checking / re-checking of the side rail and getting everything lined up.
I started getting the enternal alignment via cleco'ing a 'scrap' skin to the side rail.
But changed to duct taping the scrap to the fuse and then cleco'ing the rails to it.
Then it was drilling the rear of the rail into the hoop rib. If I was doing it again I would bring the outer hole inboard by 1/8" to help with spacing / clearance against the web.
After both rear sections were completed, the foreward plates could be drilled. One thing to watch is the lower/aft hole on the hinged section is very close to the aft most skin rivet location. I will probably just open it up to an AD4.
The fruits of todays work - lots more match drilling and finishing to do but the basic structure is complete.
