I'm paying about $11.40 per sheet, so I'm not complaining.
I am not skilled at bending tubes, or welding so I am do it with the CNC machine to cut the foam (relatively accurately) straight from the 3D model. There is a lot of 3D information that I could not otherwise move from the virtual world to the real one.
Today I helped my brother Nathan strip shingles off his roof (two layers!) so I will be sleeping very well tonight. Tomorrow brings more sheet cutting and g-code generation. Wednesday and Thursday are possible roofing days -- he is adding sistered rafters and new plywood sheathing, so they can install solar PV panels. He and his wife each drive EV's, so after the system is installed, they can drive for free!
