Another look at one of the feet. I have a series of ‘pads’ around the Harp body – the intention being to first – add a little detail to the stand and … secondly – provide holes for NBW. Printing NBW at this size in WS&F won’t work .. the printer resolution just isn’t good enough. The 0.025″ dia would be sufficent for the shaft of Tichy NBW. The 0.040″ dia holes – the idea there is to insert appropriate size wire pins to anchor the stand. Finally, the 0.064″ ida hole is for the connection rod.
Again .. these are simply the result of scaling up the O scale Harp Switch Stand .. but seem to be reasonable to me.
