Thread: Routing odd 3D shape

If I was routing that shape, this is what I would do.

1. Measure - you need a really well done contour pattern of the shape.
2. drill - use a drill press to drill holes into the material following the contour pattern and using the depth stop to stop the bit just short of the required depth. I would guess that a larger bit would remove more material more quickly, but a smaller one would do a finer job. Pay your money take your choice.
3. Rout/carve - use the router (or chisels etc) to remove the waste. You would need to do a very careful freehand, or use a lot of patterns based on your contour pattern and making sure you get the depth right.
4. sand - you will end up with a series of terraces that you will need to sand smooth.

I took a few more photos and did a SketchUp model based on the dimensions to see if I could calculate the angle, which I figure to be about 12 degrees. The sides seem quite straight like it was machined prior to painting.
So perhaps this may not be as hard as I first thought...

Here a better idea of what I am trying to achieve... if I used 10mm thick clear acrylic it might need 4 pieces side by side to get a width of about 40mm
The green bits would be the clear acrylic.
