Had a little time this evening so I assembled the rudder pedals per OP-3 plans as I am going with the ground adjustable rudder pedals. I had already fabricated the thrust washers in a previous setting so I only had to check for fit and drill the 1/8 inch holes to #12 for WD827 brake arm. Installed bolts and torqued nuts to 25 inch pounds. Measured rivet placement for mounting angles and had to stop there.
