I’d had several hours on the machining centre this week
blocking up, drilling and tapping a batch of motion brackets - 24
brackets, 120 holes, debur while the machine gets on with the next pair…
Having finished, the parts were washed down, labelled and put in the parts bins
leaving me ready for a cup of tea and something more diverting for an hour –
so out with this Simplex which came in earlier in the week.
It’s actually one I’ve had before, just come back in
part exchange for a Sweet Pea. I rated it last time it was here, so it was no
surprise that it steamed up quickly and ran very nicely on the rolling road –
it goes well, keeps itself in steam and water, safety valves are a joy, opening
spot on the red line and snapping shut with a most satisfying thwock.
Commercially-built silver soldered copper boiler by
Chambers with superheaters, working pressure 80psi, feed by injector, axle and
hand pumps – the injector is plumbed to pick up water from a tank on a driving
truck. Gunmetal cylinders with slide valves actuated by Walschaert’s gear with
pole reverser in cab. Mechanical lubricator behind buffer beam driven by
eccentric from leading axle.
A good engine, it runs quietly notched up nearly to
mid-gear. I like this one.
