I cant imagine I took the time to read this whole thread. Iron handrain... enough said. Its weldable... modifiable material. Forget shooting 1/2 inch at 14 feet. You would die before you finished thoes holes and to think you would hit a few inch core drill spot at that depth is just rediculous. I dare you to even try it with a 1 inch bit. Just to compare we did a 6 foot one with an alluminum jig we made thru a rock for a water feature. With a jig and a 3/4 expansion bit we ended up off by an inch. No big deal but imagine being off by 3 inches. Pictures!! where the heck are the pics. Now back to that rail. Think about suggesting some sort of decorative pockets to be welded into the rail. Something small enough to hold the Vista rail light or Toms suggestion of the roberts step light even in LED then run a small ga wire. Maybe some nice flower boxes welded to the railing with a light concealed in a pocket underside ?
