   Post on Drilling holes in fuse tubes in Kitfox III

   By HarbinAK, posted 10 Jan 2019

   Hi...I’m currently building my firewall.  I drilled the horizontal holes in the tube between the outermost engine mount holes to attach the firewall.  I have built the starter shroud, but it looks like one has to drill and attach it to the tubes also( v tubes to lower engine mount hole).  Maybe I’m wrong, but I hate drilling into tubes.   The manual calls for drilling holes for the seat and the cross over tubes between the wing attach points for the windshield and skylight.  Seems maybe I can attach the seat with cable ties.  I guess my main concern is the windshield and skylight attachment.  Has anyone attached the aluminum formers with adel clamps or such :  as not to drill into the tubing.  Maybe it’s not an issue, but I figure it’s better not to put holes in that structure. 
   Thanks
