Routering sidewall with a bell bit.

Has anyone routered the sidewall of their ski with a bell bit? As to try and eliminate as much chipping?

My thought was "if the sidewall is rounded into the topsheet, edges might not chip and break it as easily"

Any thoughts?

What is a bell bit? Not sure if I have heard of one.

I think he means a normal roundover or filet bit.

I see. We call these round under bits.

Yes, Praxis uses these bits with the same idea of less chipping.

The problem I see is that the degree of rounding is not consistent as the thickness of the ski varies. The underfoot part of the ski will have the most round over while the thinner tips and tails will have less. This is the opposite of what you actually want.

Shown here around 4.10:

I think I've seen Movement using a blade, so perhaps it worth exploring. If you found the right blade, then I'm sure you could set a blade within a length of wood, so the angle of the blade changed as it was drawn along the ski.

To get a feel for this method, place a ski on a flat surface and take a block of wood 20cm in length and watch the angle change relative to the topsheet as you draw the piece of wood towards the bindings. This is a good way of getting repeatable results without the 'oh no, my router ate my skis moment'.
