S Not a problem! Drilling smalll holes thru the hollow section will not affect the strenght measureably. I have my wing tank fuel lines going thru the hollow section. See page 141 of the wicks catalog if you have one. I used rubber grommets where the lines go thru the plywood,.....less than 50 cents apiece. Small diameter rubber tubing will also work. Run it thru the spar, tie it off on each side of the spar with wire ties so it stays put, cut off the excess and run your wires thru....softer, more forgiving than hard PVC P ----- Original Message ----- From: "Serge VIDAL" <serge.vi...@sagem.com> To: <kr...@mylist.net> Sent: Tuesday, July 05, 2005 12:09 PM Subject: KR> Holes through spars
