CNC-cut cross sections - Cross sections CNC-cut for an early version of the "X1". While precise, the CNC router is limited to a minimum radius on inside corners, requiring additional work to either square the corners by hand or add fillets to the solid-wood parts with additional cutting operations. After considering other CNC cutting methods, I decided it was likely faster, and definately more cost effective, to cut the parts by hand without ready access to other CNC cutting equipment (at least for a prototype).
