Cutting Applications 

Jerry Work in his manual shows how he uses the MFS as a fence for the MFT and as story sticks to 
place guide rails for cutting or routing. In this section I'll show how I have taken Jerry's techniques and 
adapted them to my own work.

 

 

 

 

Using an MFS profile as a story stick is an easy way to accurately place Festool's guide rails. I use 
one of the angle stops with a profile to set razor blades to act as stops for the rail, 

John Lucas' idea

. 

Install the angle stop in the profile, with the scale up. Using the scale I set the square on the 
measurement I want. Then butt the stop up to the square and tighten the bolts.
