Went to Sherwin Williams yesterday and picked up a new can of gray self etching primer. $16 for a can of spray paint, holy cow! Continued taking apart and deburring the fwd fuselage today. decided it would be a good time to crank out the F-782D angles and match drill the F-782 cover plates while I had easy access. laid out location with straight edge across the F-782 & F783 support ribs, then removed the F-7101 gear web to match drill. WARNING! If you try to drill this all in place, it would be ridiculously easy to drill through the side skin. Theres not even enough room behind that gear web to get a standard cleco in there before you hit the inside of the side skin. Speaking of, I wanted to cleco this all back together to mark where to notch the F-782D angle, but as I said, it was to tight to get a cleco in there. I scrounged a couple of clecoes out of the trash bucket that had bent nibs and ground them down so that the nib was exactly the same length as the barbs. That gave me just enough clearance to get them to engage before the hit the skin behind the gear web. Created notch with a rotary file, then match drilled everything, including the fwd lip of the F-740 seat floors, which need a hole match drilled for a nut plate hole thats already located in the F-782 cover plates. Used a #20 strap duplicator for that hole. Spend the rest of my shop time today deburring, countersinking, etc. on all the supporting structure thats coming out of the fwd fuselage. Will have more of that next time.
