Building my 1/12th scale PQR Charles loco has progressed to the boiler stage. I'm using 1/16" copper sheet, and 1/16" wall section copper tube for the boiler barrel. It took a long time to finalise dimensions, poring over photographs and trying to get the basic proportions. The firebox is very similar to the Quarry Hunslet's, but a little longer, and again, all wet
