I decided to try an experiment - carving the topography around my area. This is about 10"x15" douglas fir, and was carved using a 1/4 for roughing and a 1/8 ballnose for finishing.
It’s the area around Mission, BC, and includes some large lakes.
Here’s the start of the finishing pass. This wood was very stringy - I gave it a haircut before running the finish pass.
About 1/2 done the finish pass
Some low angle lighting showing the relief
The topo data came from ‘Touch Terrain’ (https://touchterrain.geol.iastate.edu/) exported as an STL, and converted to G Code using STL2NC (STL2NC - javascript edition)
The photos don’t do it justice really - the piece is very tactile.
