I've looked around but I can't find the answer to this. Please excuse me if its somewhere obvious.

So I understand how basic scales can be made. But the way I understand it they can only be flat. How do you get scales that are rounded (ie they stick out into the 3rd dimension.) I have heard this referred to as gun stock cut scales but I don't know exactly what this means.

I can't imagine that you just freehand it on a band saw. So how is it done?

As always, thanks for quenching my thirst for knowledge,
