Category: 4: Fuselage (Page 53 of 156)

I’ve been sick with a lung infection the last week, but I’m finally feeling better. So, got a bunch done today! 🙂
I did finish the fuel lines last sunday though. Getting the fuel lines to cross behind the fuel valve, and to still have them look nice, took a while, but I’m quite pleased with the results. 🙂

I decided to split the lines midway, as making these lines in one piece and get them in place would be more ore less impossible.

So, today I started on the flap drive mechanism.
First I drilled the flap actuator weldment clevis holes to 1/4″. I noticed that it have started to rust a little after having been stowed away for all these years. It’s the same deal with the rudder pedal weldments. I will have to sand these down later on, and apply epoxy primer and a new topcoat.

Next project was the F-680 block. I marked the bolt hole locations…

And drilled.

Dow! After drilling the holes, I noticed that the block should have been trimmed in one end. Well, no harm done, the hole I drilled was still outside the trim line…

Fast forward a couple of hours, the block length trimmed, a new bolt hole drilled, and the block cut in half. Last thing to do, was to make a notch in the forward end, where the block overlaps the forward floor.

Then I used the block as template to drill bolt holes in the floor.

Also notched the F-748 channel cover.

Now a lot of parts had to be manufactured. First the F-766C plate:

Then matchdrilled to the F-766A channel:

Then I made the F-766B angle..

The F-767 plate is to be made of a piece of 2024-T3 .063″ plate, but I used this EF-604 plate, which comes with the electric flap kit, but is intended for the RV-6. The angle had to be adjusted a bit, but that was no big deal.

The finished F-785 angle:

And the F-766D bushing…

The foot-angles for the F-766A channel were pre made though. Plug ‘n play! 😀

Last thing I did today, was to drill the F-785B angle to the bottom of the F-785A backrest brace, and fitted and matchdrilled the whole thing to the fuselage.
