Thanks for the reply Nobby.
I suspected that there was a story behind the name especially as 70047 didn't have a name and your choice of your grandfather's name is a great way to remember someone who had such an important place in your life.
David Heys' site has some great photos and details of 70047. If you haven't already found it it's here:

I remade the crankshaft for the lubricator tonight; I'd been putting it off for ages as the lubricator had been a thorn in my side. Still don't like the Reeves ratchet wheel they supplied, but what else can I do. The teeth just seem very shallow.
Anyway, the lubricator is now almost complete bar the second half of the ratchet pawl mechanism (I've made the advance tooth, just need to do the one that prevents it turning backwards).
Not enjoying this bit..

Not enjoying this bit.. I may have some spares left that I made some years ago if you want one? I can have a look in the workshop Saturday if I remember! I made mine as I was making a batche of lubricators and started off buying the reeves one which like you say have very shallow teeth and were next to useless so they all went back. Let me know if I can help, Adam |

I'll see if I can find them at weekend I'm sure I've got a few left, welcome to one no purchasing required! |

Took my locomotive to the track last night and during an AGM snuck in a quick test to see if I have the gauging right. The more experienced engineers seemed very happy with it, so thats good enough for me. It rolls so well, I'm sure I'll ruin that with the motion work!

You'll be fine Nobby, as a good friend of mine used to say, 'It's not bloody rocket science' he used this phrase often, even if building a working rocket. No obstacle is too big or difficult, just work it one step at a time...  good luck Pete |

I was once told off by a scientist for saying hat something or other "wasn't rocket science".
"Rocket science is dead simple" he said, "you just squirt something out of one end and the rocket goes the opposite way...…. it's rocket technology that's bloody difficult!"

  I apologise for the quality of the second image, its not a great camera on my phone and its a lot worse when covered in oil! Made a little progress on the couplings tonight, nothing stellar but pleasing enough. Every step is still a little nibble forward. I'm trying to take my time to keep the standard of finish up. It won't be anywhere near exhibition standard but I don't want to be ashamed of it either! |

You've much to be proud of there Nobby, your coupling rods look great.

 I really need a new camera, this one is terribly blurred, my apologies! This is the linking point between the front and rear coupling rods. I've rather astonished myself; through repeated measurement before taking any cuts I managed to get the joint properly flush; i.e. damn near perfectly in line. I'm not usually that lucky. Short bit of video of the motion being checked. |

Does this result mean that the jig worked? |

Does this result mean that the jig worked? It would appear so, for the first couple of axles at least! If its ok can I hang on to it for a little longer just in case any rework is required? I know you said you were not in a hurry for it to be returned but I don't like to sit on other peoples stuff for too long! |

Have confidence Nobby, you are doing a great job and it's not due to luck but you thinking things through and being careful.
You should be very happy with the way that everything works so smoothly I for one would have been thrilled if Boadicea turned over as smoothly as that first up, that's when I discovered the 'Fitting' side of 'Fitting and Turning'.
Looking forward to more posts in the coming year as 70047 progresses.

 Another rod has sprouted. Still seems to move silky. Now to do the same the other side. I won't update every time I do a little thing, just the bigger lumps. |

Looking good Nobby, your doing a fantastic job there. Incedently, I have quite a few photos of Oliver Cromwell if there are any detail shots you need, just ask.
