Thank you very much all, what I wanted to cut things like frames for pictures or door frames
I already have a MFT but a bit big to move around.
I found a solution with 3 items.
the SYSTAINER T-LOC SYS MFT (500076) with screw clamps
the 32" Guide Rail FS 800 - (491499) which I will cut into two pieces to make it easier to handle
the Dogs as suggested or the angle unit (491588) with a small mod to make sure it does not move. A shown in the picture I would be making holes once I'm sure the most used angles are accurate and a piece between the holes (in red). Hope this is clear
