Rollbar Painted Part 1

Early in the morning I prepared the parts for painting. The primer had dried nicely and the surfaces were quite smooth. To remove minor imperfections I sanded them with a maroon SB pad and then started the painting. Paint use anticipation was dead on and while the parts were curing I worked on section 29.
Most of the dimpling of that strip that goes on top of the FW I had done yesterday so now it was to rivet the nutplates and the strip in place. That went relatively easy although slow. A lot of care had to be taken to get those rivets in and the overlapping skins flat. Some of these needed the screw to go into the nutplate to hold everything down and in place.


Then the piano hinges for the cowl had to be match drilled. If you haven't cut them to length yet, make a note for 1201J, the longer one of the two hinges. The manual asks for it to be cut to 25.5" length. That is incorrect. It needs to be 26" long with the loop starting on the lower left side of the FW and that flat side in that little cutout area where the hinge pin ends will be stored.
How I know? Look at this:


I had to drill an extra holes to rivet down the end of the piano hinge and will have to fill the unused hole with a rivet.I believe the page where this incorrect length was mentioned had a revision number. Stuff like that just makes me angry. The drawing is incorrect either as it shows two loops on each end which is not would you need to do here to get the hinge over that hole.

After match-drilling and the deburring the holes had to get countersunk for AD3 rivets.


And then the hinges were riveted in.


And finally the rest of the vertically mounted nutplates were riveted in and the antenna platform was riveted on.


Then it was time to get the parts out of the paint booth and put them in the shop for the night.


They turned out nice, tomorrow the opposite side will get painted.
