Began drilling W11-02 and W11-06 Wing Attach Assemblies. * Drilled pilot holes in W11-03 Wing Attach Blocks on drill press. * Drilled up to 3/16" holes in Attach Blocks. * Clamped Attach Blocks to Attach Angles in workbench vice and drilled through the Attach Angles
* Clamped Block/Angle assembly in drill press and drilled 2 bolt holes up to 1/4" on one piece.
These 1/4" holes were called out on plans as "tight fit", but they were too loose on the first piece. Per Kerry Fores (Sonex Tech Support), these two would be OK, but I should correct the other three.
I stopped at this point to get some advice on how to drill "tight fit" holes from fellow EAA 44 member, Vet Thomas, a professional machinist. See Tips/Techniques for this.
