Okay, I watched the video, Seyco came up with the magnetic top, it is standard on their saws. It is not zero clearance, but I say that is the bases for this tip....I will say, I did not care for the magnetic top, not sure why, but I gave mine away. I have heard other Seyco owners like it. But more importantly, that little hole will not stay little for long. I use zero clearance on my saws. I have learned that the little hole gets enlarged by the blade movement and blade breakage, and forgetting to set the tension before starting the saw.... That is why I built my aux, table tops so I can use inserts that I can make and change out as I wear the old ones out. I do not have to pay +/- $20 for a new magnetic top. Attaching the top is easy, on this type saw, four counter sunk holes, using the original screws that hold the real table on. Some just use double sided tape to hold the aux top on. That seem to work good.
You can see by the picture how the hole get enlarged after some use.
