Hornblocks on a Pantograph Machine

I thought members might be interested in my solution to scale axle box horns, these are for my Wainwright “DEE” type. My new machine, a pantograph engraver can be used as a light milling machine and to this end I machined the horns on the end of a piece of bronze bar. The template was made from plywood at a scale of 10/1 and worked out quite accurately. Only a couple of “thou” required filling out to make them to size. As you can see the rivet holes are also drilled on the pantograph.
The next operation was to part off , then file the angle on the webs to give a cast like appearance, I suppose a shot blast would improve the appearance and provide a nice surface key for the paint.
This operation takes me back many years to my apprenticeship as a toolmaker around 1956, seems like eons ago, all the best to the club.
