Extrusion machine angled corner molds

I saw the angled corner molds.  Can the person doing this shed some light on the progress?  Looking to make chairs with the extrusion machine.

@btmetz, I think it’s @timslab who’s on it…
if you have a plasma around you could slice one side off the tube and use ejector bolts to get it out and to form the shape, use a ring roller and/or traditional blacksmith techniques to bend the mold if you like it a little more roundish 🙂
