I think of drilling holes through the hollow part of the fore and aft spars, inside the cockpit, in order to route the various wires, and the Pitot-Static tubing. At present, they go around the spars. - Has anybody done that? - How big can I make the holes? - Do I need to reinforce the plywood where the holes are? - What could I use to plug the holes, to prevent chafing? (I was thinking of using plastic (PVC) tubing)
