The dimensions for the journal boxes are currently set to 47" from back to back (along the axle), and the distances between the fronts along the axis of the axle are 67" at the top of the journal, 71" at the widest point (ignoring the lid).

I like designing everything for 26" wheelsets.  In On3 or Sn3, we can always choose to use a smaller size.  Price, availability, performance, and looks are what we want...and the Kadees are a nice combination of those attributes for HOn3.

I thinking about spreading out the HOn3 brake shoes just slightly to allow for the slop I've left in for the axles.  I'm trying to decide how much clearance to try this time.  I used a 55deg axle cone based on RPs or Ss...I think.   I might try printing a few different variations to experiment with how much clearance is desirable.

A beautiful thing about 3D printing, mistakes in the "tooling" are easier to fit than with other techniques.

The test prints are postponed until I can check what Phil posted against my models, as well as to see what Randy turns up.
