great video. however, @4:55 that undersized 3/4" bit is actually loose it seems in the video. A good dado joint should be easy to put/slide and should not fall out without holding it. I have looked at the undersized bits as well and looking at reviews the best accurate set is by Whiteside #470 and is just over $50 on Amazon
You should figure out your volume, your voice volume is low and the music and tool volume is way too loud. It was too frustrating to watch in it's entirety. Cheers
