Nice to begin a new section! The usual deburring and reading ahead to prepare the parts for priming.
Final-Drilling the #30 holes in the F-01490 Nose Gear Brackets. I did this before priming the Firewall Angles & Tunnel Sides.
Machine Countersinking
There are lots of holes to be machine countersunk.
But not ALL of them, only the ones which align with a dimple in the firewalls, so care is needed to mask off the ones the manual says NOT to do!
As you can see in this manual extract (27-04), it might be easy to overlook some of the holes in the left Firewall Side!
I planed off a corner of some wooden blocks so that they could act as a support for the angles while on the pillar drill.
I got fed up with manipulating the blocks to leave a little gap for the countersink pilot, so I screwed them together!
So once all the countersinking and dimpling was complete I primed the parts. I still have to debur and dimple the stainless steel firewall parts.
The tunnel sides are visible in the cockpit of course, so I decided to finish them on the outer sides with my 2K Cockpit Paint.
Since the 2K paint is very hard, I also thought I might as well put it on the Firewall Angles.
