Me and my projects
Category: AKKA/Tierra
After some struggling to get the bolts through the holes I realised that I had to redrill the.holes again. The holes has gotten cold and smaller, and the paint has went into the hole.
Don’t forget the seat belts.
It is quite roomy.
Like a flying duck.
Just to see the difference.
Jag är ett sätt att tänka.
Coming together nicely. The akka gear is strong and sturdy. I even have a pair of extra strong spring leafs for the float version. Heavy stuff.

I just had to start building. The latex paint is drying and waiting to get sanded before final coat.
I have ordered new bolts from spruceaircraft.eu but I hasn’t gotten it yet. So I am preassemblying with the old bolts first.
The twin root tubes had to be knocked into the cross tubes with the power of lube, rubber hammer and muscles.
Akka has special wing mounts.
Just the engine mount plate left to be mounted.
Jag är ett sätt att tänka.
This is the last tube on the fuselage to paint. I still have the wing struts left to paint. I am getting tired of painting now. But it’s soon there.
To keep my motivation high, I started painting my sails. The rudder and fin is already painted in silver. But I want a nicer look. Made in Sweden! 😉
I have been reading a lot about using latex paint on fabric. So I will give it a try. I bought Beckers acrylic paint based on latex. I am diluting it with windshield washfluid. Using a foam roller, I am applying very thin layers and letting it dry. Before painting again I sandpaper the surface with 400 paper and then go for a little thicker layer and so on. Later I will use rubbing and wax to get the gloss.
It sure is nicer to work with this stuff rather than the toxic poulerathane primer.
I still have several layers left to apply. Time consuming, but nice.

I wanted to see if my prop was in balance. It was. But after my small repairs it won’t be anymore, so I am going to need a balancer. You can buy expensive ones but all you need is this simple but precise homemade tool.
Check the balance by reading the bubble position and the cups position on the top. Turn the bubble tube to check the balance in different directions.
Add epoxy as balance weight. Don’t forget to balance the prop in all directions. The cup souls be in the center and the bubble should be in the middle in all the directions.

The brakes and rims is in good condition. The old tires is staying on until it’s time to fly. I rolled on some extra layers of paint on the leaf springs, it should hold up good. The rims got several layers of wax and wax sealer.

Just to get some work variation, I started working on the landing gears. The brakes needs to be taken all apart and get cleaned.
The leaf springs are going to get sand blasted and painted. I will use my airplane primer and maybe I will put on an extra layer of top paint.
The wheels are really bad, all cracked up. Let’s call Goodyear 😉
The main gear and tail wheel leaf springs, waiting to get in the sand blaster.

The new tubes has alclad coating on the surface that needs to be eliminated before painting. You can use etching chemicals, wash-primer, alodine coating or just rub it down with fine sandpaper and scotch brite before priming with Epoxy or polyurethane Primer. It all depends on how the climate is were your plane is operated. In Sweden we don´t have to hi humidity and salt water in the air. Tierras and Akkas was just Painted with Epoxy paint and it last many years. But it needs to be looked after. I think polyurethane Primer is bether than Epoxy Primer because I think it´s more flexible and can withstand erosion better. JAS39 Gripen is primed with polyurethane primer and at many places it is the only paint used. But SAAB uses wash primer/ Alodine on all their parts before priming. But I am not rebuilding a jet fighter… Or do I…?
