Here is a shot of the tool I made so that I could accurately drill the additional holes in the rear spar of the center section. it worked great.
You can see one of the extra holes on the left side of this picture. I had to drill about 60 extra holes on the top and the bottom.
Back on to the fuel tanks. I had to rivet the nutplates on the sending unit access panel:
Saturday morning I went over to a fly-in at Pink Hill. There was an abandoned KR-2 project in one of the hangars with this logo:
I always heard KR-2s were pigs!
So we took the center section off.
And the vertical fin needs a little work such as the tip cap:
These are the center section access panel doublers. There are 12 nutplates on each of these, there are three. This drilling took over an hour with the deburring and countersinking. They will be alodined and primed before attaching the nutplates.
And here is the ELT antenna doubler being drilled. It will eventually go underneath the skin. Again it has to be primed before permanent attachment.
