[modeleng] Re: Gauge Widening

Hello Peter,

Thanks for that.

In fact, after looking at the wheels more closely, in this case it most 
definitely is the flanges.  Firstly they are very deep (even compared to my 
narrow gauge profiled wheels) and secondly (and most importantly), when I 
looked closer there is no "root radius" so the wheel is rolling on a hard angle 
on top of the rail, not on the curved surface.

Now these wheels are a batch I bought quite a few years ago (and in fact I have 
a dozen left that are planned for part of three pairs of  Queensland bogies, 
however before use I shall be turning down wheels to a more realistic narrow 
gauge profile, in particular the depth of flange and root radius.

By the way, I found my 7.25" guide last night.  You are allowed to gauge widen 
by 1/8".

Cheers

Peter
