Prepping the horizontal stabilizer for mounting - 4 hours

 On initial fitting the horizontal stabilizer. I notice that the F-711C vertical bars interfere slightly with the flanges on the HS-00005 ribs. This is a bit of a head scratch-er on how best to handle this. I am reluctant to remove material from the F-711C vertical bars, but trimming the flanges are near impossible. Well....I ended up doing a little of both.

 First I decided to chamfer the aft outside edge of the vertical bars. It soon became apparent that alone won't be enough without removing lots of material.

I then started in on the impossible task of trimming the flanges. To do this I cut a piece of 0.016" scrap material and carefully slipped it under the flanges.

After a lot of filing with a tiny file...I finally managed to remove the material. Keeping the shims under the flanges, I can then use 3M scotchbrite to buff the cut edges. After masking off the piece, a coat of primer...Ready to start mounting.
