To my fellow RV Friends,
Another slow week, Daytime Job had a new IT computer system go live, so it took up most my evenings and even my weekend
I did manage to start on the wing ribs. There is a lot of boring work here. The ribs are of the 'worst' pre-manufactured parts you get from Vansaircraft, so they need a lot of attention to get them airworthy. I guess all these ribs get done on the same machine and that machine takes a hammering with the amount of ribs it needs to do.
OK this is what I had to do:
1) First you need to debur the lightening holes in the rib web. They are very rough.
2) Next you have to take off those ugly white stickers depicting the part #. What a pain, since it interferes with bending, deburring and priming.
3) Next you need to bend the rib flanges 90 degrees to the webs all around, you need to do this because they are punched out of sheets and the bend is not 90 degree. If you don't do this your wing skin will not set flat. In the picture below is my bending pliers and set square.
4) You need to debur the flanges.
5) You need to flute the ribs to get them to lie down flat and straight.
In total there are +/- 60 ribs, below you can see the main ribs that goes between the main spar and the rear spar just before the Flaps & Ailerons. I am about 30% done with the rib preparation, so don’t expect ground breaking photos soon.
Till next time..Deburrr,deburrr....Deburrr,deburrr 
Kind Regards
Rudi
Here you can see the same amount of stacked ribs, before and after fluting...nice and striaght.

you get the general idea, but it actually goes:
