while looking for something else I came across this & gave it a read. I've seen this same thing on you tube & have to say it raises a lot of concerns. these jigs for circular saws & table saws are accidents waiting to happen. it's just a matter of time before a piece gets caught & is launched across your shop resulting in a jammed finger or thumb or an injury from that wood striking you resulting in a lost eye or other injury. I've been a union carpenter & home shop wood butcher for over 40 years. I've worked residential, commercial, & industrial. I've been around a lot of machinery, flown 30.00 ib. loads with cranes, & installed industrial machinery & robotics. I have a stringed instrument repair shop & build bee woodenware. AND I still have ALL of my digits. I do not like the handles that are added to the outside of hive boxes. they take up room in the shed & I just do not like the way they look. so when I found this I went for it.
