Drilled all angle pieces to LH main spar (pilot hole size). Marked LH inboard spar web for what is countersunk, what is bolts, what is countersunk bolts, to know what size holes to drill. Could use some more deep 3/32 clecoes, but should be able to make do with the 15 that I have. If you don't have deep clecoes (advertised as 1/2" grip) in all the sizes, you need some here.
