This listing is for PDF plans and DXF cut files to make your own welding square tools which can interface with 0.630" or 16mm hole welding fixture tables, OR 0.75" or 19mm hole size fixture tables, to be cut from 0.25" to 0.50" (6mm to 12mm) steel plate.

Also now included are versions with true dimension 0.625" holes for more accurate cutting machines.

All versions have holes spaced 2" on center. 

All three 0.625inch, 0.630inch and 0.75inch diameter hole size versions are included.

This project requires welding and CNC cutting.
