The trace-width depends on TWO things:  How much CURRENT ("amps") the trace 
must conduct, and how SKILLED  you are in making a trace.  0.01" is found on 
professional PTH boards!  

0.05" wide traces are "healthy", and easy to do "manual" work.  0.125" is 
quite wide, actually!  You could pass three or four amps through a 1/8" wide 
trace with no problem.  I forget the site, now, where it describes how to 
calculate a trace-width based upon current to flow through it.  Someone else 
remember it?
