Unfortunately, we don’t have a build log - it was all a bit of a mad rush to get the car on the grid after the first stab at the bodywork failed - Happy to answer questions tho’.
Various observations from the top of my head:
Overall shape, slices, and toolpaths were all developed using Fusion360 - and included locating holes for internal dowels.
EPS70 foam was cheap and OKish, but for a better finish I’d probably go with styrofoam (blue/pink/gray).
Be prepared for a lot of dust - will need a hoover stooge.
Helped to use a good quality long reach ballnose cutter - eg: 8m dia, 150m long carbide cutter. Cheap things off ebay had a bad habit of shaking/bending.
Did lots of dry runs of the worst case toolpaths to check acceleration settings - we had to really dial it down to cope with the steep parallel passes
We did (IIRC) four passes with spackle and abrasives to get a good finish before skinning the plug - much easier than trying to shape that after epoxy+glass skin (even so - had a few rounds of bondo afterwards).
We were not too bothered about surface finish (and were in a hurry), so laid up the final body shell directly onto the plug, rather than making a mould such that the good surface is outside. If we need another, we may make the effort to go with a mould.
