Wendell Folks RV-8 Project - Page 30.

October 7, 2006:  The engine controls had to be installed again temporarily to insure the proper clearance of the control cables through the left main gear leg tower.  We discovered that two of the holes needed some additional work to clear the control cables.

The first of the rubber "O-rings" to stabilize the control cables is installed.  The next step is to insert one of the control cables, then fit up the stainless steel shields that will be installed over the rubber parts.

Back in the cabin, the plastic bushings were installed for wiring and the two air lines from the LIFT RESERVE PROBE that will be mounted underneath the right wing access panel to the aileron bellcrank.  We had the foot wells laid into the floor to be sure the air lines would not have an interference fit problem as they come in from the wing, loop around near the floor support rib, then penetrate the wing spar box.  The two 1/4" plastic bushings will pass the air lines for the LRI gauge on the instrument panel.  The large plastic bushing near the control stick assembly will pass a number of wires going from the switch/breaker panel to wing lights, strobe power supply, master relay, etc.

Here are the matching bushings installed on the front of the wing spar assembly.  After uploading this photo to my computer, I realized I should have turned on the "macro mode" in my camera to take this shot.

The last shot of the day shows all three engine control cable access holes drilled to full size.  These holes are now at 3/4" diameter to accept 1-inch rubber "O-rings".  The gascolator now has a steel plug in the fuel line access hole on this side.  The fuel primer solenoid will be mounted nearby after all the control cables have their stainless steel shields installed.

October 12, 2006:  The session with Wendell tonight checked his recent work and charted his next building steps.   There is a lot to see in the photo below.  Let's start at the far right side of the photo.  The clearance holes for the control cables have now been fitted with stainless steel fire shields and the large rubber grommets have been removed.  The screw holes for the shields are now visible above and below the larger holes in the firewall.  The next thing new is the solenoid for the primer system and the copper lines from the gascolator to the valve and continuing to the first tee in the primer lines on the engine.  The copper tubing is "armored" by some left over brake tubing from my surplus materials.  There is an expansion loop in the primer line as it approaches the engine mount.  That half loop bends toward the camera is not very apparent.  The starter cable has been shaped to fit along the route from the crank case going to the starter solenoid on the firewall.  Two clamps will hold it to the engine mount when completed.  There are now three heat shields on the exhaust pipe near the fuel line going to the carburetor.

Behind the gascolator in the photo above, you can see the first view of the crankcase vent pipe up against the firewall.  This is the initial fit of the pipe and its mating rubber hose up on the engine accessory case as seen in the photo below.   The hose has been trimmed to a length that provides needed clearance from the oil filter and the oil cooler hose that will come from the blue AN-fitting near the center of the photo.  The spark plug wires are just draped where needed to stay out of the way of the other work going on.  Those coiled white wires near the center are from the oil temperature probe, which will be connected when the engine monitor is installed.

Here is a view of the number two cylinder and primer lines there.  The original primer lines that came with the engine are installed along with the brass tee fittings.  Ansel clamps have been installed on the intake pipes to prevent oscillations of the primer lines between the tee and the cylinder heads where the brass AN spray nozzles are installed.  The front end of the large starter cable is also visible.  There will be one Ansel clamp installed to secure that cable to the flange above the oil sump.

The view from the right side of the engine shows the control cables from the Lasar ignition system.  Wendell has placed a clamp on the cables where he was checking the attach point to the firewall I recommended.  The "breather tube" from the crank case is also visible.  It will get a second clamp installed down below the fuel line coming from the gascolator to the fuel flow sensor.  The lower end of the tube will also get trimmed to insure proper clearance above the left exhaust pipe where any dripping oil should be vaporized when it hits the hot pipe.

Now that things are getting full on this side of the engine, it was also time to insure that a grounding point on the firewall was selected for another large cable to give a return electrical path for the starter motor.  The ground cable bolts to the crank case near the oil dip stick and the engine mount seen in the top right corner of this photo.  All those colored wires from the Lasar ignition control module will soon find an entry point through the firewall.
