I made big progress today installing the mounts for all the cabling as well as the pitot and static systems. First I made a simple jig on the drill press to cut out evenly spaced 5/8" holes in some strips of 0.063" steel. These holes will be lined with 
SB625-7 plastic bushings to protect the cables. The plates were made with varying numbers of holes from 1 to 5 depending on the cabling density in various parts of the fuselage - there are probably more routes than needed but the experience with the RV9A of trying to get additional cables through a limited number of routes persuaded me to be more generous this time. Also, the wiring scheme keeps sensitive antenna cabling separate from power cabling The basic routing is from the panel, over the fuel tank and down between it and the firewall, then under the floor through to the baggage compartment. Once clear of the elevator pushrod the cabling will then sit on the inside of the fuselage through to the tail and then up the front of the horizontal stabiliser spar to the rear light/strobe. Behind the baggage compartment the route also branches up to the top of the fuselage and then forward into the rear spar cover where the pitot tube and wing cables will enter the wings and where the GPS and Comm antenna are mounted. Five smaller plates to take SB375-4 bushes were also welded round the fuselage uprights and top cross member at station 111 to take the static tubing from the left to the right side of the fuselage (picture 4).In detail the routes are as follows:
Route 1: Panel to strobe pack power behind station 78, panel to tail nav light, panel to wing nav lights, strobe pack to tail strobe, strobe pack to wing strobes
Route 2: Panel to wing mounted pitot tube, panel to comm antenna behind rear spar carry through, panel to static ports at station 111
Route 3: Panel to GPS antenna behind rear spar carry through, panel to wing mounted VOR antenna
Route 4: Panel to autopilot servo behind station 48
Route 5: Panel to transponder antenna situated on the left side of the floor between station 0 and 18, fuel tank to breather port situated on the right side of the floor between station 0 and 18
