There is a bit of slop in this arrangement, so removing/reinstalling the rail can change the angle of the fence slightly, but for me setting the drift angle is not a particularly precise adjustment anyway, and the slop doesn't seem to cause a problem. The second picture shows the backside of the rail and the studs / wingnuts that hold it once it is installed. The first picture is a shot of the fence and rail when it is installed. I cut slots into the edge of the extruded angle so the wing nuts only have to be loosened a bit to remove the rail. Normally 2 of these hold the removable reinforcement bar that runs across the slot once the blade is in place.
The extruded aluminum is then attached to the table using wingnuts on studs (actually, I just use bolts) threaded into the 4 threaded holes along the underside of the infeed edge of the table. Rather than attach the rail directly to the table, I attached it to a length of 1-1/2' x 1/8' extruded aluminum angle. Unfortuantely, on the Rikon the slot for changing the blade comes out to the infeed edge of the table and is blocked by the Kreg fence rail. The Kreg fence rail bolts to the infeed edge of the table. I thought someone might like to see how I attached a Kreg Precision Fence to my Rikon 14' Deluxe Bandsaw. Kreg Precision Fence on Rikon 14' Deluxe Bandsaw
