Reamed the bushings on the control column to 1/4 inch as specified, and trial fitted (is that english?) the hardware for the control sticks. I'm getting some wood block spacers from another builder to trial fit the wing spar mounts to the center bulkhead in a week or so. Started in on the 705 bulkhead by getting busy on the bandsaw. Cut the 705B to length and cleaned up the edges and then marked a centerline on it. Fabricated the 705H spacers and 605C bar doublers.
