Hi...

Our house was wired for cable when it was built in the 70's with old
rg59. On top of that, they horseshoe nailed the cable to the studs.
I started re-wiring it with rg6 but ran into a snag in the back
bedroom.

The wiring starts in the basement, runs up the center of the house to
the attic, then through crawlspaces, etc back down to the bedrooms.
One bedroom that we're using as an office has a drop, but the jack is
in the mid-line of the house, so it runs back and forth under a lot of
sub flooring.

My problem is those damn horseshoe nails. I broke the top out of the
wall box and was able to pull out one of the horseshoe nails with a
coat hanger, but there's another one somewhere up there in the wall.
Because of all the zigging and zagging under the subflooring, a snake
wouldn't work to run a new line. My understanding is that snakes work
okay if you have essentially a straight shot, which I don't.

Any ideas on how to free up the line/get rid of the horseshoe nail
somewhere up the stud without taking all the drywall down?

Thanks
Mark
