My first F&F jig made of two scrap blocks of 6/4 poplar, about 5 x 10? inch with a maple bar at the bottom that was hand planed to the exact width of a Hammer K5 sliding table's T slot.? I still use them on the K3.? No flip stop, no tape scale.? They are clamps to keep my hands away from the blade for cutting small stocks.? It's important that the jig is squared to the table travel and blade.
As expected, David B.'s F&F jig is the most fancy that I have seen.??
