Router Fan Carving Jig remix

This is a jig for a router you can use to quickly carve inclined fan rays into a wood surface, to add a decorative element to your woodwork.

It comprises templates, which attach to the work piece with clamps, and a routing ramp, which sits in indexing holes in the template. 

Different templates provide for a variable number of rays.

Different routing ramps provide for different incline angles and sizes of rays. All the channels are sized for a 3/8" bearing or router bushing.

Printing

The templates are smaller than the original and can be printed on the smallest of beds. The ramps vary in size, and the longest ones can only be printed on larger beds.

The templates print flat. The ramps should be printed top face down (the indexing pegs in the base facing up). No supports required.

I've provided a few options to start, but I'll be adding more templates and ramps.

Print your choice of template and ramp.

Routing

All power tools, including routers, have the potential to cause injury, and you use these templates entirely at your own risk. You should be familiar with safe use of any tools you use, follow safe practices, and should wear appropriate personal protection equipment when operating power tools.

I recommend using a palm router, with a bushing that fits the minimum width of the ramp slot, but a smaller bushing (or router bit bearing) will also work - you'll just have to move the router around to clear out the wood.

Clamp the template to the workpiece, and secure the workpiece to a fixed work surface.  You may find it necessary to move the clamps to provide clearance for the ramp as you move the ramp around the different index holes. If so, keep the workpiece and template secured to the fixed work surface with at least two clamps at all times, to prevent slippage.
