Today I spent about 2 hours sorting my parts by section number. I am doing the standard fuselage kit. There's a LOT of sub kits and a LOT of parts. Several of them needed to be primed (welded steel or other steel part-not stainless). I set up my computer and used the parts index to sort them all by section number. This was a long, tedious task but it will make the upcoming sections a lot quicker to gather the parts. Also, the same index list shows the material each part is made of so if you need to prime something that's deep in the build, this is a good time to check if it needs to be primed now or not.
After that, I got to work on the many, many ribs and doublers that are waiting for me.
I do enjoy this part so it was a very enjoyable day!
