Wiring Custom-Built Switches

[NW Modeling List]

Gordon, 
  
I fill the gaps with styrene and epoxy in place; I then file the styrene to shape; this prevents the gap from ever closing.

I agree that using Fast Tracks filing aids and soldering templates significantly improves the quality of hand-built switches.  My question is about wiring custom-built switches.  Like many articles I have read, I fill the frog/closure rail area with solder and then file grooves.  I have been cutting gaps in both closure rails and just beyond the frog and then power-routing the frog.  I am concerned that cutting these gaps increases the possibility of miss-alignment of the rails.  Has anyone had problems with shorts between stock rails and closure rails using DCC?  Is a slightly wider gap between the closure and stock rail adequate to prevent a short?
