Couple of things to consider,,,, i know everyone wants steel.. Steel is going to require a lot of after casting clean up machining... Steel casting do not come out as smooth a ZAMAK...(zinc, alum,copper ,magnesium ). Scanning and coping the real Mauser is no problem ill have some results to show in the next couple of months. I want to finish the Aluminum E11 project before i start the Mauser casting.... What kinda cost do you think the steel is worth??? It may have a lot of sanding a polishing required to get the finished your used to in the mgc and denix??? Remember the real Mauser is machined and exp.. Just some thoughts
