Very neat Ron!More pics please.Hopefully your pump will be more reliable than injectors sometimes aren't!

Just noticed, there's supposed to be a series of holes round the gland nut for a locking device which I've forgotten to do, although I would have preferred a hex nut if I'd had a big enough bit of hex bar. Hopefully it should work well, the ball valves all passed the 'sook' test and the ram's a good sliding fit in the body, the O-rings made it a bit tight but it'll loosed off with a bit of running. I've made the slip eccentric but I'll leave the strap till the front axle's fitted.

Re the locking device,it would depend on what access there is to the gland nut one the loco is finished.Usually the access is very limited.
I not sure you actually need a slip eccentric to drive your pump?Maybe a plain eccentric securely fixed to the shaft (e.g. with a grub screw or keyway) would suffice.
Interesting the name 'Goodwin' cast into the stretcher.

Laurie Woops, I meant a plain eccentric  All the Blackgate castings I bought had 'Goodwin' embossed on them, very good quality. Ron |

Ron,
Just checking!!!
The casting interested me,as my brother started a Simplex quite a few years ago,and I seem to recall the stretchers were specified as cut from 3/8" steel plate.The casting seems a much better idea.

Hi Steve
I don't really feel I spend a huge amount of time in the workshop [maybe the wife would disagree!], I found out when I was restoring classic cars that I have to keep working at a project, even if it's only a small token gesture, if I was to leave it for a couple of months or more I would be in danger of losing interest.

'Goodwin' comes from Dave Goodwin, a castings supplier who was based in Rishton. He sold up a few years ago, the 2 1/2" association had all his 2 1/2" stuff, looks like Blackgates had the rest. His shop was a proper hardware store, and he wore a white smock! The castings were at a desk to one side.
