Has anyone been successful using a Kreg pocket hole jig on 1/2" material? I have used my Kreg jig lots of times with 3/4" material. I followed all the instructions - inserted the blue spacer in the bottom of the jig, reset the collar on the drill bit, used 1" screws. The ends of the screw holes are very close to the edge of the material and when a screw is inserted it blows out the face of the other piece. I tried moving the stop collar, but that resulted in a shallow hole and the screw forces some material out into the joint. I guess I could drill a shallow hole and then drill a pilot hole for the screw tip the rest of the way through the material. A bit of a pain to do it that way, but... Any other tips? Thanks.
