We continued with the rudder assemble today. Dad focused on the mounting and I continued with the pedals.
First thing for me was to re-trim the 8 angle supports for the pedals.
The brake side plate needed some more edge clean up work, but with the radius of the corner being quite tight an improvised sanding tool was needed.
Dad worked on the drilling of the plastic blocks. Note the end blocks are handed, the rudder tube is drilled in at a slight angle.
The rough setup. Dad then moved onto the support bracket.
We decided no to trim the support at all and provide the maximum flexibility for rudder adjustment, although I doubt we will need very much movement. A notch has to be cut for the firewall angle.
Sabre saw for the longer cut and then some further trimming and filing.
I moved on to drilling the angle supports. I elected to pilot drill the lowest holes on both the aft and sides of the angle supports via a jig to give an repeatable and accurate hole. These were then opened to #30's for the pre-punched rudder pedals.
Using the drilled locations the angle was clamped and the rest of the holes could be completed. Careful support for the angle (with the radiused internal corner) was needed.
The parts starting to look like pedals. I then marked up the trimming for the 'non-master cylinder' side angles.
I did the trimming in a two stage process, starting with a rough cut with the hand held rotary burr.
And finishing with a burr in the pillar drill plus a 2 axis vice. I made a wooden wedge to set the angle for the final line. These can then be smoothed and finished. To be continued tomorrow.
