re: Kreg system

My wife bought me a Kreg Jig for Christmas. She saw the infomercial and thought it would be the ideal way to get me to build her a sewing box. She did get the sewing box, but I never touched the Kreg during the build. I have used it though. I found that it was the perfect way to attach the MDF top to my POS bench. When I get around to building a new top, replacing it will be easy.
I could see using it in other projects like jigs and such, but never in place of mortise and tenon, or other traditional joinery in furniture. I don’t want to get into the habit of “easier is better”. Frankly, I just don’t trust the screwed butt joint, with or without glue.
