[modeleng] Re: Steel Wheels

Charles,

The tyres will bo 7.25 inches across the flanges so I was planning on 0.007 
inches of interference.

Good point about alignment - I intend to lay the tyre on two horizontal bars 
about 4" apart, heat up the tyre then lower the wheel set ( the wheels are 
already on the axles) into the tyre. Both wheel and tyre should rest on the 
horizontal bars.
