Pansy (5 Gauge)

Overview
Pansy is an 0-6-0 GWR Pannier tank locomotive designed by LBSC to resemble a 57XX Class Great Western locomotive. It was described in Model Engineer magazine Vols 118-150. It has a Cylinder bore of 1.5" and Driving wheels of 4.875".

Drawing Errors
Braking system: The brake hangers are threaded 1/4" x 40T to screw into the frames. The frames are 1/8", and the dimension on the brake hangers gives the thread at 3/16" long. That doesn't matter on the driving wheel as there is plenty of clearance. On the leading wheel, provided you have drilled and tapped the cylinder block as well, it again doesn't matter. But the trailing ones would pass through the frames where the boiler is. Therefore it is best to make the thread only 1/8" long.

Boiler: The drawing does not show enough stays above the firehole door, however these are described in the original "words and music". LBSC's original article should be read and understood prior to building the boiler to ensure these stays are incorporated. Failure to do so will result in a design unlikely to be passed by boiler inspectors as potentially unsafe.
