Mark,
I just used that theory for the first time myself. I used Q-Tip shafts to guide, and protect cable going throw some jointed wood parts. Just epoxy glued them in, a few minutes ago. Trying a new hinge system I have been sleeping on for a while. I will take a few pic's, and post them in a bit. The drill size 3/32 did help the wondering problem, and may work quit well with your pin situation.
