Fwd fuselage

Started deburring and countersinking the pieces before mating together the fwd and aft fuselage.

Main gear

Speculated a lot how to drill the main gear to get it straight and also get the holes perpendicular. Ended up using the fwd main gear support angle to steer three holes that I hand drilled 4-5 mm into the main legs, but upside down. Then I put it upside down under the fuselage and pre-drilled (marked) the rest of the holes. Then I took it in the drill press, and got perfectly perpendicular pilot holes. When I test-mounted, it fitted perfectly. Have to up-drill the holes for the AN5 bolts.

Fwd fuselage

Drilled more holes, also for bolts. Found out (too late) that one of the holes in the corner will be impossible to use. They are too close to other bolts. They can be be inserted the opposite way.

Fwd fuselage

Drilled up all the holes to 1/8 (at least the ones I know shall be 1/8). The nice step by step map "stops working" here for countersunk rivets. Used lots of time just studying the drawings to find out where and what to countersink, and in what order in relation to the drawings. I think I got it sorted out, and I also have to mate the aft and fwd fuselage to do it.
