A Couple of Photos

I tried a new "raw brass" material in Shapeways with the AAR dummy coupler design.   Seems to have worked pretty well.  At one time I made these copulers in FUD, then had some brass models made using those as investment castings.  These are better, in my opinion.  I need to edit the design a wee bit to loosen the grip up.  When coupled it is -tight-!
