Crosscut Fence Stop (Mafell)

I originally designed this crosscut flipstop for my Mafell Erika table saw, but with a few modifications of the slider it can also be used with other fence profiles  or even other machines like a drill press or a crosscut saw. Feel free to remix.

The STEP files are now added for your own rework.

This is a more advanced project, because for assembling you’ll need some additional hardware and some post-processing for a really precise tool. You’ll find a BOM at the end of this article and an assembling guide is attached in the picture section. 

The flip-stop is - like at professional table saws - designed to use on both sides of the fence. In some cases this is very helpful, even when not common for “household” machines.  On the original Mafell stop, the ruler is positioned as if the zero point were on the saw blade. This means that the exact length can be read directly on the stop flap and no additional reading aid is required. Of course, the cross fence must also be set precisely.

Notes

Because this is a piece of heavy stress at the machine, it should be as strong as possible. To achieve this use a filament which is meant for machine parts or prototyping in mechanical engineering. For parts like this I always use my beloved Fiberthree CF Nylon, as seen on the pictures

Postprocessing

To ensure precise guidance of the stop, the two seatings of the axial ball bearings should be slightly reworked with an 18 mm end mill so that the ball bearings sit exactly perpendicular to the shoulder screw in the housing.

To help the stop slide more easily on the aluminium profile, it may be helpful to apply some ceramic paste to the underside of the sliding piece (the white colour visible in the pictures of the underside of the sliding piece).
