Here is a little contraption I use to sand intakes and other awkward places. This idea was borrowed from Zoltan “Neu” Pocza.
The intake has taken quite a beating from the sanding and filler needed to remove the gap and step where the intake meets the fuselage.
The port side has fared no better than the starboard!
Because I had to sand the intake interiors it became necessary to repaint them. This meant I had to re-mask the engine compressor blades. Here I am making up a custom mask for one side.
The final result looks a lot better than what we started with. Makes it worth all that sanding.
