Dimpling the Left Wing Leading Edge

https://www.annarosamattei.com/?p=y6vvak8 Back to work on leading edge.  I managed to get all of the left wing leading edge parts ready for priming in tonights session.  I also captured a time lapse, and you’ll see at the end a lot of reading and standing / looking / planning.  I am not going to count that work in the total time 🙂

follow I started out by dimpling the ribs for the left wing leading edge using the pnematic squeezer.  Its faster and easier than using the Numatx squeezer on ribs at least.  These went pretty quick, and now they are completely ready for priming.
