Located this first parts for the HS - rear spar, doubler and evelator hinge brackets. For some reason, the plans have you final drill, prep, amd rivet these componets right off the bat. Since I was waiting for the weekend to arrive so I could batch prime the VS and rudder, I figured I try and get these parts ready as well and add them to the pile for priming. Pulled at the spar (man is it long) and promptly tore a hole in my 3-veiw RV-10 drawing on the wall with the spar as I was swinging it around to place it on the table--arrgghhhh. Removed the plastic from the spar and the doubler. Edge deburred the doubler and started on the spar.
