(page 27-02) Rudder pedals and brakes...............            

Skipping from 23-04 to section 27 allows installation of the pedals and associated plumbing without having to reach around the side skins.  This situation has occurred several times where it seems advantageous to do things out of order with the build manual and it always leaves me wondering if I'm missing something which will later bite me.  The various steps for the trial fitting and assembly are easily understandable and fun with one notable exception: maintaining the proper orientation of the parts while match-drilling the steel tubes.  The picture shows the assembly in the proper orientation which it will assume when suspended from the firewall shelf.  It's put together and drilled upside down, with the assembly resting on the bolt heads through the nylon blocks.  In that orientation, the brake pedals are supposed to be clamped so that they are vertical.  Problem is, it's hard to keep them that way while match drilling (first #30, then #12, finally 1/4 inch) through the steel tubes.  The top of the pedal on the far right ended up a bit too far aft.  I'm attempting a fix by slotting the hole with a rat-tail file, then filling in the opposite edge of the hole with weld material, thereby moving the hole circumferentially.  After being spoiled by drilling so much aluminum, drilling steel is a challenge.

[Update:  After pondering the situation, I decided to abandon the fix described above.  I ordered a new pedal and torque tube from the Mothership and, rather than match-drilling in place as described in the build manual, will do the drilling in v-blocks on the drill press.  The plan is this:  Install the new parts on the assembly as before (positioned upside down from what's shown), using the pilot holes in the pedals, mark where the holes go in the torque tube, then take the two parts to the drill press and complete the drilling.]
