Thanks Brian..

As I suspected, now Sonex instruct people to drill the up to 1/2" with just the two spars.

You did it as after put together with the fuselage. Is yours B model or A Model? It shouldnt make any difference

Mine is an A model. I drilled the spars on my drill press, with the last pass using a slightly undersized reamer. That gave me a light press fit on my AN6 bolt. Then I built the wings.

My wings were already built as it was a conversion. I clamped the wings together and used a magnetic drill press to drill the blocks. Then rigged them to the fuselage and drilled the rear tunnel first then installed the front tunnel and drilled forward. It was a perfect fit without reamming.
