Similarly, for cutting out the body, one will either need to source a tool able to make a 1.75" deep cut, or do this as a flip job and cut halfway, or finish on a router table or something:
Assuming one can find an 0.25" endmill able to do this, offset the outer geometry by that dimension plus 10%:
Apply:
Next, it will be necessary to cut the neck pocket out from the body of the guitar (maybe we should have kept some of that open geometry) — since the nodes of the geometry should be set up to allow this construction, we select both:
copy-paste them:
Go into Node Edit Mode:
and cut the two vectors open:
and delete nodes until we are down to just what is needed:
Then, draw in the missing line segments:
Select everything:
Join Vectors:
Yes
Drag everything into alignment:
Edit the pocket toolpath for the neck:
selecting this new geometry and the offset:
Changing the vectors so that the file now previews as:
Then select the outer and offset geometry and do toolpaths down to tab height starting at the bottom of that pocket:
Then do a contour toolpath starting at the bottom of that pocket with tabs:
which previews as:
A final refinement would be to offset the outline geometry by the radius of the tip of a roundover tool and cut that geometry to a suitable depth to get the rounding, or one could do that on a router table, or with a suitable handtool. For the roundover tool, see:
