I started using the Kreg R3 Jr. for the first time today with 3/4" plywood. I have 2 questions for those of you with more experience.
1. When I drilled my holes, I noticed a small amount of blue plastic shavings coming out with the sawdust. This decreased as I went on, but I'm worried that I'm already messing up my new jig! It didn't seem loose and it didn't seem like I was doing something in particular to cause it, just drilling straight into the holes as directed. Is this normal the first time it's used?
2. I'm using Kreg brand 1.25" coarse maxi-loc head screws as recommended for plywood. When I use my drill, set for driving screws, with the square driver bit from Kreg the screws will not go in all the way - I reach a point maybe 2/3 of the way in where the drill just won't turn the screw anymore. I can drive them all the way in with a manual screwdriver without great effort, so it's not like I'm hitting some impenetrable spot. Has anyone else had this problem? I like the whole pocket hole concept, but this is not exactly as fast as I'd hoped!
