No problem, Barry.
I use the dado in my table saw, not a huge amount, but when appropriate. I have a shop-made guard that attaches to the fence when cutting close to the edge of a workspiece. If its a foot or more in I just use the fence to guide the piece through, no "safety" gear. (We are talking cabinet sides, really) If the dado is buried in the workpiece (except when entering/leaving) I have no problem with it.
As to kickback-never had ANY experiences with it. A regular blade, yes. The dado-no. The blade is cutting in line with the cut (as opposed to rotating the opposite direction, like a straight router bit) and it is a quiet, clean cut. No mess, multiple takes, jigs, etc. Just set the fence, depth of cut, turn on the vac and voila, job done in a few seconds, minimal noise and fuss.
I feel the majority of problems with dados in the UK are down to using them in saws that are NOT suitable. You need a heavy duty machine that is designed for it. It is quick to set up (not much longer than swapping saw blades), quiet (and that is a REAL benefit to most hobby woodworkers) clean (all the waste gets sucked away by the saws extraction) and you can cut it in one pass.
I would love for you to all pop by the workshop and see it in action. It is a REAL LET-DOWN. You just set it up and make the cut. No horror stories, no fuss. All UK dado users I have spoken to have said the same thing-you are expecting all sorts of terrible things to happen when you switch it on, fueled by Internet old womens tales. In the real world (well, mine :lol: ) it is a much more simple story.
So-bottom line. Used in a suitable saw, and within it's design application, a dado head is a useful tool in your workshop. You may not use it every day, every week, or even every month. But sometimes it is the best tool for the job.
Hope this is of help,

please note-this is my own personal opinion. Your safety is paramount-never perform an operation you feel is unsafe.
