The Rail Fence is for making cuts off of the MFT table. It is a precise 90 degree fence that slides onto the bottom of a Festool Guide Rail and allows for accurate cuts while away from the MFT.  It was designed and works great on rail lengths up to 1400 mm (55 inches). It can work on longer rails but may be a bit awkward in use.

The Rail Fence slides onto to the guide rail through the groove on the bottom of the rail. It has 2 methods for accurate alignment with the rail or you can use any square to align it. Two thumb screws lock the Rail Fence in position. You can still install the hose guard / deflector if desired.

You do need to remove 10-12 inches of foam rubber from the outer strip on the guide rail. It is easily removed with a hair dryer and a scraper or razor blade.

The Rail Fence is about 17 inches long and 10 inches wide. It is a precise 30/60 degree right triangle. It’s 3/16 inch thickness provides for a rigid, sturdy fence while keeping it lightweight.

How accurate is it? Good question and one that should be answered by anyone making squares. We are keeping the error to .002 inch per foot. However most errors will not be from the fence but rather from the reference edge that the fence rides on. Any error on the reference edge is also added to the total error. A thin 1/64 inch sliver on the reference edge at the end of the fence can cause a 3/64 error over a 48 inch cut. It is important to have a clean reference edge to get a good accurate cut.

Small screw holes have been added for adding  an auxiliary fence. The auxiliary fence can be wood or an aluminum extrusion. This fence could have a scale and/or stops on it for cutting multiple pieces to the same size.

Rail Fence Bonus Feature

That’s right, there’s more. The Rail Fence works with the MFT table. With the use of our Qwas Dogs, the Rail Fence can be used to align the guide rail on the MFT. But more important, the Rail Fence can be used as a fence for cutting 30 or 60 degree angles with the MFT.

Screw holes allow for an auxiliary fence on any of the 3 sides.
