I primed the fuel tank attache brackets for both tanks and bolted then to their respective spars. Tried the fuel tank baffles up against them only to find that I'd fitted them facing the wrong way around, and so had to take them off and refit them corectly. I then drilled the baffles and six outer tank attach brackets. as a personal feeling I think it would be better to mark the angle bracket with a centre line on each flange with a mid point marked on the angle and drill the spars/bolt holes, but not drilling the baffle rivet holes until the baffles are mated onto the attach brackets, I'm sure there wouldn't be a problem gently clamping the baffle so that it was straight and wouldn't move, then drilling the baffle/bracket holes.
