Id 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.
Its actually one Ive 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 Walschaerts 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.
