Hi Ron
I did this job a long time ago and asked the factory for guidance before
cutting holes in the ribs. Neville told me to put in two plies of bid in the
form
of 2" discs before drilling the 3/4" holes I needed for my conduit.
I would not make the holes any larger than necessary. Surely you don't really
need a 1 inch diameter tube?
Regards
John
