I continued with the routing of the control cable to the butterfly valve. One would think some of these items would take only a few minutes to perform.....but by the time you decide on the course of action then mark and drill holes, install pass throughs....before you know it almost three hours have passed!!!
I added the adel clamp on the rear side of where the cable exited the gear tower on the angle attached to the fuselage side skin. I then located the firewall passthrough. I found a Bowden 3/16 inch cable clamp. The size was just right and I carefully located it in a small area between the side fuselage skin and the firewall angle and drilled the hole for installing it.
Last step will be attaching the cable to the butterfly valve arm.
