UJK Technology Bushes are used in this instance to create a simple curved finger pull which could be used, for example, on the ends of a large box. Instead of using handles, here’s another method of providing a handhold for a box or drawer. The Festool OF1400 router has been specified, but other machines can be used with the appropriate guide bush adaptor plate.
What you'll need
Use an oddment of 8mm ply to make a circle jig, mark a line down the centre. At one end, bore a 25mm hole for the router cutter and two smaller holes to bolt it to the base of the router.
Don’t over tighten the bolts as there’s a possibility of stripping the threads in the router base.
The radius of the finger pull was set to 250mm by drilling a small hole for a pivot screw at the correct distance.
Insert the 19mm cutter into the router and screw the circle jig into the template material. The router will now cut a curve with a radius of 250mm. Plunge the router several times into the template to form a curved shape of the required length. The last cut should pass completely through the material. Unscrew the circle jig from the template material.
Clamp the template to the project such that the curved finger pull will be routed in the correct location. The final width is 15mm (19-2-2=15mm) as the cutter is worked firstly along one side of the template and then the other.
Remove the cutter and bush, replace them with a bottom bearing chamfer cutter. The hard edge of the finger pull is softened by machining a small chamfer all the way around.
