First bottom positive polished to shine.

The positive was wet sanded to 2500 grit. Then I spent several hours polishing with the coarse 3M polishing paste. After some time, my arms didn`t want to polish anymore, and started to hurt like H****! -Then my magnificent girlfriend stepped in and finished the job for me! :D Thanks alot Annette!

Now I have three more to go before next wedensday. Hope my arms last that long... -Tonight I probably be sitting up and admireing the finish, instead of sleeping....

The positives are finish painted... :)

Just collected the positives at the car painter. They have been sitting there over the weekend to harden, after I finished painting them on friday. The finish is already really good, except for a few small spots were some dust is stuck. But that is easy corrected. Now they are going to be left untouched for a couple of days more before I start carefully to wet sand them with 1200 to 2500 grit. After that they will be polished to perfection with two different 3M perfect-it III polishing pastes . Then I`ll start waxing with PAT921. After that I have to go back to Tromsø to have my last exams ever at law school!!! I finish this christmas! YEEEHA!!!! -When I can find time to do the moulds, I`m not sure. It depends on how much UAV activity there will be this summer. As some of you know, I`m a part time UAV test-pilot at Norut (Link)

I`ve also attached a picture of one of my DLG wings which I pulled from the bag today. Their weight was 135g. for both panels including paint. I`m happy with that! This is with 58g/dm2 glass skins with 49g/dm2 doblers on the flaperons. I`m looking forward to flying some DLG competitions this summer.

Finally an update again.

There has been done alot of work since last update... And I`ll never complain about the cost of a mouldie again...

The steelframes for the moulds are ready thanks to Andreas`s great welding skills.. :) -Then my father drove 600km. to pick up me and the wing postives in Tromsø. We drove the 600km back to Lofoten the next day. Yikes!

The first week was spendt sandig of the light marks from the mill. I used 400 to 800 grade sandpaper on a big block. The sanding is just slight, and it doesent hurt the airfoil accuracy, as you will add about the same in paint later. I also had alot of trouble to find a place to paint the positives, and was almost thinking of just painting them outside.. -Then a friend of my father tiped me about a retired car painter who had a small professional paint shop next to his home. His name is Kjell Moe ,and he offered to help out. -Last night we primed the positives, and I have wet sanded the positives with 800 and 1200 grit sandpaper today. We will paint the positives with a special 2k. PU paint on friday.

I have also made my first carbon joiner. Its in UMS with depron cores, and is super stiff at a weight of 120g, which I hope will go down to 80g with experience. But I`m happy with it, as alot of production joiners weigh the same.

At the same time, I`ve bagged 2 disser DLG wings for this season, as I`m a bit hooked on the DLG thing also.... Damn hobby! :D

Today I`m very happy!

Today UPS dropped a large and heavy package from Germany at my front door. - As you might have guessed it contained the wing positives from Bodo. On the outside the package looked like it had passed a war zone on its way up here. But Bodo`s clever use of a Epp crate (Maybe you should patent those?) saved my positives, and they arrived in perfect condition. Bodo has done a great job with the milling, and the surface finish was even better than I had expected. So there is not much sanding to do before I can apply the paint layer. Another cool thing was that my handmade joiner fitted perfectly!!! (That must be quite a bit of luck...)

Today a friend from work, Andreas, is going to weld the steelframes for the positives. Tak & Metall here in Tromsø was very kind to give me a really nice deal on the steel, and the also helped me get it cutted to right lengths for welding. Thanks alot, I really appreciate the help guys!
