Hi Robin

From your description I am guessing you are changing scales. The fact
you have 1/8* sections on your mock axles, means you have 4mm axles,
and you say you are making a 7mm coach.

All you need to do is have the 3/16" part of the axle protruding a
small amount, say 5mm, just enough to locate the "Wagon Master's". Use
the longer fixing screw to attach.

The 32mm is for when you are building a 7mm loco chassis using 7mm
axles, i.e 3/16" for the whole length.

I hope I have understood your problem if not please reply
