I want to make a riving knife for my table saw, as the one that came with it goes higher than the blade.
I would like a riving knife that matches the height of the blade fitted in order to resaw 8cm wide lumber in two passes, so roughly 4cm at a time. Then I'd like to use a cross cut sled and some other scenarios like that.
Although it would be easier to modify the existing riving knife I don't want to as the blade guards attach to it so I would never be able to use that feature.
It isn't straightforward to find 2mm or 3mm thick aluminium or steel sheets. However, I can buy some 3mm thick Aluminium DIBOND® for art purposes. Will this material be suitable for making a new riving knife?
