A big day today working on the flap actuator. I started by making the various small pieces from stock aluminium, then I alodined and primed them. Rather than alodine the larger pieces I decided to simply give them a scuff and spray with acid etch primer. Different colours, but that doesn't matter. Any part of the interior that's visible at the end will be sprayed with a grey finish coat.
After the paint had dried enough then I started riveting the pieces together. There's also quite a few nutplates to fit on these sections. This whole assembly needs to be removable for inspection or repair.
Anyway, it all went toegther as per the instructions. Very time consuming, but rewarding to sit back and see another part of my aircraft finished. I hooked the flap motor up to my 12V power supply and ran it up and down a few times. Seems to work okay. Tomorrow I might make up some sort of bracket for a wiring plug. I'll have a think about that tonight.
