Tried to figure out proper routing of spark plug wires, control cables and oil cooler lines. Got completely frustrated with spacing and the use of Adel clamps. I despise those things. Hard to install and get in the proper space. Decided to do some mind numbing sanding on the left wingtip and touch up the trailing edges of both wingtips. Should probably route the mag wires from #2 and #4 cylinders over the top for length and security. Means I have to undo all the work I did the other day. One step forward two steps back.
