Very cold in the garage this morning (25F) at 5:15am. Started riveting the top RH HS skin to the front spar (702) and center rib (708). Went well had to drill out one rivet - no biggee. Finished it up and I will flip it over and do the bottom skin tomorrow and then I will move back to the LH side to rivet the end and root ribs. These are along the edges so they will be squeezed rather than bucked - must faster and easier for me at this stage.
