Drilling Curved Cable Holes Seems Like A Dumb Idea

If you want to "curve" a cable, drill a hole, drill another hole meeting the first hole, fish a pull wire through the second hole with a "knitting needle" (a short snake with a sharpened hook), and use the pull cable to get the cable to curve. Using this "curved bit" will seriously weaken the beam.

Here's a video of the 'cured hole' fixture:

One big drawback of this fixture is it isn't adjustable. The demo beam is basically all the tool is good for punching through.

I agree that doing this will weaken a structural beam considerably. Running cable at a right angle without destroying beams is not brain surgery; it just takes time.

Ari's approach using two perpendicular holes makes good sense!

The solution in the video appears to maintain a standard minimum cable bend radius, (3-5x cable width).

Could one based on two perpindicular holes, in a beam that size, do the same?

Agreed though, if the beam falls apart, it doesn't really matter.

Sure, just drill the two perpendicular holes at an angle.

"Perpendicular" was indeed the word I was looking for. Man, I hate Mondays.
