Dick Kerr WDLR 07

Everyone is probably getting bored of the Dick Kerr right now, but it's moving along.  Work has kept me away this week, but I still managed to finish up the cab.  I'm so happy with it that I'm going to take another crack at the sides--I think I can do better.  The test print of the cab is in the printer now.


One thing of note is that I "relieved" the windows in the cab, meaning I tapered the section of the wall near the window so they look near scale thickness.  This allows a thicker body wall. I'm going to give that treatment to the body sides.  You can see the tapering around the windows and the holes in the transparent version below.  I'm waiting to see the test print before I decide how to break it apart.


The other major step forward was developing a WDLR coupler.  I've designed it to work in a Kadee draft gear box.  I'm making a custom Kadee style box for the Kerr.  This way I can use standard Kadee centering springs, and allows for Kadee/WDLR couplers to be interchangeable.



My WDLR coupler head is faithful, save for an additional vertical hole I've added to allow for coupling with a small staple.  It's based on drawings and photos.  Here is the first test print.


Note the heel of the coupler is extended in this version--I had momentarily thought of an alternate centering scenario for use on a WDLR bogie, but quickly realized that the Kadee spring solution was a good one.
