Thanks so much guys, I’m looking forward to finally using this saw. Yes, the blade is behind the knurled knob, it’s just kind of hanging there. It was after taking the pics that I went back and fiddled with it a bit more and figured out that the blade goes in front of it. I wanted to make fancy birdhouses, and I’ve never used it. I’ve had three people try to help me with it, and no one was able to figure it out! Obviously over-thinking it. Thanks again. Joanne
