-8A N192NM, forward mounted battery, AFS-3500, AOA, ADI II Pilot, Strobe power pack mounted in aft bagage compartment, electric trim and indicators, Infinity Stick Grip, electric flaps, pitot and static lines under the floor, flodd lights - all of which require wires/tubes through the spar assembly. I drilled holes through the web(s) IAW Van's wiring directions, but have run out of space for additional wires through existing holes.
Can I drill another 3/4 hole through the web(s) without compromising strength? I understand the flanges take the load, but intuitively, it seems there has to be a swiss cheese limit.
