Another great photo album with ideas for the headtube connection.

I think you are mad to drill into the underside of the HT-DT joint area, lug or not. On another forum and the facebook framebuilders group there have been recent threads showing lugged bikes failing just behind here, cracks seemingly starting in the stressed area between the top and bottom points of the lugs. In one example a hole for a dynamo wire contributed to the failure, I think it was drilled on the side of the DT.
Also, I think drilling so close will require you to have some arrangement to allow for the fork turning, e.g coiling the wire in a pigtail in a tight area between fork crown and tube. Lastly, I've never liked these low mounting points for light which seem less visible than a higher mount and also more liable to be damaged by pedals etc of other bikes.
Mind you, my bikes are covered with zipties or dynamo wires wrapped around frame tubes/cable housing as a result so the aesthetics are maybe not my strong point :) I wrap the rear upwards around the brake cable then a pigtail over to the top tube

I'm hoping the coax cable stuff makes a bit more sense once I have it in hand as it's all seeming a bit double dutch right now.
My usual method of cable stripping is rolling it along a stanley blade, take it that ain't gonna cut it!
Worst comes to the worst I have a mate who makes cables for the tv and film industry and I know he deals with coax so will probably be able to help me out.
I think in under the DT on the lug, down the DT, over the bb, into the chainstay out at the end and into a light mounted to the mudguard eye.
If you're using Coax, might I suggest looking at the stick-on Di2 guides before you bust out the drill. They can make a setup look really clean without risking your frame.
I've put about two years of all-weather commuting in Seattle on my setup and they've stayed put without issue.
