Floorboards are in so it was time to install the rudder pedals. Got the position dialed in on the fuselage by centering the center pivot/bearing and then working on the ends where I found the least resistance to the pedal movement. Clamped that down and then checked the overall assembly to see if it was straight across or a bit cattywompus (technical term). Turns out it was fine - maybe a 1/16" out of line which I attributed to the bearings on the center and end brackets. Drilled the holes for the end brackets and then clamped in the forward floorboard and match drilled it up from the bottom. Temporarily installed the pedal assembly and then shimmed using 3/4" dia fender washers under the brackets to improve the pedal movement. The right side took no shims, the center took 1 shim and the left took 3. Finalized installing the bearing brackets and then located and installed the two brackets for the master brake cylinders using a 1/8" drill to get the proper separation between the bracket and the rudder tubes. Ended up with some very smooth rudder pedals which is great. Lots of putting in and taking out of the assembly to get it dialed in.
