After upgrading from a very old Craftsman table to a Porter Cable Job site table saw I had to make a new sacrificial fence. Some time ago I managed to get a very nice sheet of maple plywood from the cull pile after someone mistakenly cut it in half. It was hugely discounted and become all kinds of wonderful things in my shop.
This one attaches to the rip fence. It has a higher profile to clamp on verticle feather boards. And I used a U-bolt that was cut in half to make it clamp on and off easily. All inspired by folks on Pinterest.
