Today I updrilled all the holes through the main spar and root doubler to #30, the holes in the forward skin were updrilled to #32 as these will require dimpling which enlarges the holes slightly. I was wondering how I would do this as I don't have #32 cleco's, luckely the silver #40 cleco's still work for #32 holes (not all though, some of the cleco's pull straight through but then it's just a matter of picking another one). Next I'll habe to take the skins off again and deburr everything.
