I'm planning on rigging a shelf which is 18 mm sheet of OSB.
Can I just pass a cable through a grommet -protected hole in the board? Would it hold?
The sheet is 1.5 * 1.2 meters, how much space from the edge do I have to leave for each of the four points of rigging?
Specifically what kind of grommet would I need. Or should I call it hollow rivet. I know I'm constrained by the radius of wire bending to be 10 times the wire diameter.
What's the required diameter of the rivet to hold reliably in the board. Does it need to go through whole thickness of the board, or would, say 10 mm be enough? Would threads on the rivet(making it hollow screw) be beneficial? What's the diameter of outer flange required to hold the grommet from being pushed into the board.
The shelf is supposed to hold 50kg overall(not necessarily evenly distributed), that makes ~250N of horizontal force pushing the grommet laterally. And up to 400N of force vertically.
