Grigri self belaying mod, a la Bomber's directions:

Note removal of plastic which exposes the void (a Stanley knife works well) - then use a 3mm drill bit and drill a hole to allow some 3mm chord to be inserted - tie an overhand stopper knot, flame it, then pull it into the void.

Note the removal of a triangle of the blue aluminium cover (I used a round backed flat file). This allows the rope to flow more freely as you move up.
Bomber has accomplished this mod solely with his Leatherman tool.
This should be used with a D shaped mallion attaching the grigri to your harness, a biner then goes through the loop in the cord and attaches to a chest sling to hold it upright. Tie off to something solid on the ground, flake the rope into a pack on your back or a pile on the ground, put the rope over your shoulder and through the device, place pro and climb.
Note: nothing in this posted should be attempted by anyone. You are much better off sitting in your shed, reading old climbing mags and drinking goon.
