My dad (bearded codger in the black cap) has a somewhat unusual toy. He co-owns it with his mate, the other guy in the picture and they have some laughs with this thing.All my life there have been machines like this in our shed and in our lives. For work and for play. We grew up around them and many of my childhood memories revolve around the dichotomy between my mum wanting pretty (clean) daughters in frilly dresses and fun loving dad wanting my sister and I to hang with him and learn about steam and oil and boilers and pressure and coal and such things. Dad almost always won. Fun times.
