Hi -
I was looking over the Woodsmith Shop's website and came across a design for a DIY ZCI plate. They basically used a piece of 1/2 BB ply and cut a slot in it, then glued in a little wood splitter at the back - which also provided the stiffener needed for the plate.
They are using a PM2000 tablesaw, it looks like they took off the riving knife and don't even consider it with this ZCI (the splitter providing the safety function).
This seems a little wrong to me for some reason - not sure why - it's just that the riving knife is designed to rise and fall with the blade and stay just underneath the top of it (the low profile one that is). But then again, for most work 3/4" and below, the splitter does the same function as the riving knife at 90 degrees.
Anyone else that has this nagging feeling that a ZCI should still use the saw's riving knife ?
