Today I got the mounting blocks all drilled up to 3/8. I took each one off and drilled it individually on the drill press .. then put it back on. I used an intermediate step of 5/16 .. checking it was all straight as I went. When I finished the holes aligned perfect and the bolts fit snug. I also got the forward angles drilled out of the fuselage. I have more coming from Sonex. Now I'll go to work on some misc stuff until the angle parts get here next week.
