These are CNC designs I made for a friend who wanted to make a set of Talorgen chairs, named for Master Talorgen of House Barra in the SCA, see the source links at the end.
These are faux medeival chairs made from plywood and designed to be flat-packed for transport, and slot together for use, then broken down and transported again.
Here's a photograph of the chair partially assembled, I was test fitting for where the back slides into the slots of the sides:
And here are a few photos of the CNC'ing in progress:
I'm currently still tweaking/fine tuning the design, and I'm working with 24" x 48" chunks of plywood, so I currently have the four pieces broken out into two files, one for the back and one side, the other just the side. My plan is to cut these out and hand-cut the slots, do some measuring, and adjust the design for the seat based on that.
Note, the SVG files are all either 24" wide by 48" high or 48" wide by 96" high, to match the sizes of the plywood sheets they're intended to be cut from. This also means that the image files exported from those SVG files and appearing here in this web page have large chunks of white space. So be it.

The original design calls for all four pieces to fit in a 4x4 piece of plywood, to make two sets per 4x8 sheet. This svg file contains all four pieces.

Some of the SVG versions of these files have rectangles, drawn in color. Those were for fine-tuning the slots fitting together, you can delete them and otherwise ignore them, until I get around to re-editing these files to remove them.
