Bill, I don't know exactly how your mast came to be foamed....originally made as such, foamed later by owner, etc. But assuming it was foamed all the way up, the only way I can envision to wire internally would be to bore a channel all the way from top to bottom. It *might* be possible to do that with a REALLY long metal rod sharpened at one end that you would force/hammer up thru the foam. (Actually, you can use several rods and some ferrules to connect them as they go deeper in) Most likely the rod would be forced to the side along the foam/mast interface and then ride along there, but that would be OK. Once the rod tipped out at the top, you would put a guideline on it, withdraw the rod, thus pulling the guideline thru the new channel. Then attach the wire to the guideline and draw it thru. If you can find a rod of sufficient length, I'd think this would be the easiest way to go.
As far as taping it to the outside of the mast, that sounds like the beginning of a yearly (more likely monthly!!) problem of retaping it as it peels off in the heat of the sun. Another option would be to use pop rivets every 30" or so to affix plastic or metal guides. However, I'd have to wonder if this might not compromise the stength of the mast? I'd be real concerned about that...kinda like putting a perforation line along the mast!!
Boy, I sure hope for your sake someone has better ideas than these for you!! But if not, I'd consider the rod plan. Good luck!
