To work safely it is always good to have some kind of pusher to keep your fingers away from the table saw blade, router table cutters and planer knives. I have some plastic pushers, but I’m afraid that they will break if I use them with the brush and the pieces will jump off, so I thought it would be best to make me some wooden ones.
Specifically I am going to use 1cm plywood, pieces of spruce slats and a piece of 3mm mdf veneer. These are not the ones I made, but here you have a drawing of table saw pushers in pdf, which I’m sure you can use to make your own.
As you will see in the video, making a wooden pusher is not complicated and can be made to measure. The only advice I can give you is that, in the pusher for the table brush, do not nail or screw the small strip that is crossed underneath, just glue it. It is possible that at some point you will plane wood thin enough to touch the blades with it and if you have nails or screws there you will make nicks in the blades and you will probably have to replace them.
