Old school. and dependent on size of the model. Don't forget a saw kerf from a NON through cut. about an 1/8" space from a TS blade. Bandsaw kerfs are a lot less.
Like Duck showed, a few templates were the pre CNC or Laser way to get it done. Since the increase of CNC for woodworking an entire line of straight cutting bits of varied sizes. If you go "twisted" remember you want either a downcut spiral, or compression for a smooth surface. If seeing the bottom of the cut is normal, invest in compression bits, they give a finely cut top, and bottom in one pass. IOW NO splintering.
best of luck, no matter what method you use.
