Build it
Here are the various CAD dimension drawings for the GEK. The files are version controlled so make sure you are working with the most recent version. G-code files and/or tool path corrected .dxf files for CNC plasma cutting are also available on request.
In addition to the sheetmetal parts descibed in the CAD drawings, you will also need the following plumbing and auxillary parts to assemble the unit. The instructions for fabricating, assembling and firing the GEK are in the GEK wiki sandbox .
