just watched your last 2 videos. Very cool that you post these. I have just about finished the empenage kit. Have tons of video footage but haven't been brave enough to post any...

2 things based on my own mistakes...

your 3M deburring wheel will last longer if you pass the stiffners and all material for that matter 90? to the rotation. Otherwise you may get a deep lines in the wheel. Not sure how to explain it properly.

Also be careful on the left elevator with wherever there is a dimpled skin with a countersunk underlying surface. (701-L, 606PP) I guess I did a imperfect job and created a bit pillowing and that really sucked when it came time to rivet.

I was ready to start over but vans said to just move on....

Thanks for sharing and build on!
