thanks guys!
i am going to have to belt out the turned cast iron front ring of the smokebox and turn that down on the inside,
but after that ive realised that the chimney represents the last major component requiring a lot of turning and production of swarf on STEPNEY.
ive already cut up the brass for the tanks, and ive got to make all the springs (proper leaf springs) and a host of outstanding bits and bobs. i suppose if i finish all the pipework and make and fit the springs i could actually give the loco a steam up and run.
one of the most critical jobs to do next is to fit the petticoat pipe and finish the hole for same on top of the smokebox. this and the chimney must be concentric with the blastpipe otherwise the effectiveness of the draughting is seriously impaired.
cheers,
julian

 havent had much time in the workshop recently but have made a start on the smokebox hinges as per the above pic. ive always made them out of stainless, with a piece of rod drilled each end then thinned in the middle, then some scallops in the hinge straps then silver soldered. that way everything stays in line and ok. the thinned section gets cut out once the hinge straps are riveted to the smokebox. ben and george ray will notice left bottom my sketch of the oilers which is another fiddly job over the next few weeks. (i turned down the cast iron front ring of the smokebox at the weekend and fitted this plus the rear ring in position with loctite plus have made and fitted the petticoat pipe) cheers, julian |

That's a cunning way to keep those straight, I imagine they have a mind of their own when the straps are attached!

I must say Julian you're a dab hand as a sketch artist. Though not as neat as your drawings I too find it much easier to sketch out what I want to create along with essential dimensions to get a clear idea of how the task can be completed.

Very nice Julian, any chance of a more detailed method for the door hinges? I'm a little simple sometimes and occasionally need more info.
Sketch of the oiler looks spot on!
Cheers
Ben

a bit more progress this weekend... ive made and fitted the hinge blocks (stainless) to the smokebox front plus the handrail stanchions. the hinge blocks are threaded 5BA, and the handrail stanchions 8BA. hole s for same as tapping size came half in and out of the rebate on the cast iron front ring - so a few anxious moments when tapping same! no broken taps thankfully! ive also made a start on the door handles out of solid stainless. these will get two flats filed on them then drilled centrally and one tapped and the longer one having a square filed in it, then both filed to circular profile in due course. cheers, julian   |

Super neat as always Julian. Is there any particular reason why you choose to file the flats when you have a milling machine to hand? Presumably there are holes in the middle of the flats that could go in at the same time?

hi pete,
many thanks! i always think it's nice to complete the 'face' as you describe - i might even paint a face on it as per Stepney in the Rev Awdry books! (i made a face for one of my locos as per same for public running, only to find it had disappeared - apparently due to an outraged club member who removed it and threw it away!)
hi roger,
it's just a few strokes of a file and hardly worth setting up in the mill. i might do one side in the mill though as it's tough stainless it's easier to file than risk damaging an end mill and blunting same.
cheers,
julian

not everything goes according to plan!
in the above pic of the smokebox front you can just see where i'd marked where one of the lamp brackets goes at 12 o'clock...
2 x No.55 holes drilled ok for tapping 10BA, then broke two 10 BA taps one in each hole! should have gone up to No.54 for such fiddly bits in an awkward location!
drat!
cheers,
julian

hi roger,
yes a pain and no way will the bits will come out so ive covered them up with the lamp bracket affixed with a new tapped hole between the disasters! no one will know.... unless you all tell!
cheers,
julian

 here's the lamp bracket covering up yesterday evening's disaster. as all the bits for my A1X version have no proper drawings and ive judged the parts by photos etc of fullsize ive made a bit of an error with the lamp bracket at 12 o'clock on the front of the smokebox as it should be taller, though for Isle of Wight A1X locos it is the correct height! new lamp bracket required which so far will make 3 items in the scrap box the other 2 being front guard irons i'd made the wrong shape. dart door handles nearly finished out of solid stainless. the round head 10BA screws on the hinge straps will get replaced with nickel silver specially made rivets for the stainless hinges and straps. cheers, julian |

Oh well, it's annoying but that's all, no harm done. I use carbide PCB routers that have been discarded by the PCB industry when they're worn out to destroy a broken tap. I usually break several in the process but it will turn HSS to dust if you're very gentle.
I'm doing that business of guessing dimensions and proportions from photographs too, and I think that's good enough for most things. Someone told me recently that he's building two locomotives.... one for the scrap bin and one for the model.

It's all looking mighty fine Julian, a lovely job! Have you seen this? The bloke looks like the lead singer from The Darkness but he is a cracking bloke, he had a fair few days helping us out in the works at SP. youtu.be/exQyyn56sVcCheers Ben |

hi ben,
many thanks and thanks for the link to that excellent youtube film by chris eden-green.
i need to crack on with the smokebox and fit the brackets for the dart crossbar so i can then give the smokebox a coat of primer this side of the winter otherwise it's going to go rusty.
cheers,
julian

No probs! There are all sorts of other engines featured for many regions for those who may be interested! Just search in his YouTube channel.
Good luck with finishing off and painting, the tender chassis of the V2 has once again rusted over, but I don't want to paint it until all the stretchers and ideally the holes for the pipe clips have been worked out and drilled, some time away yet, guess I'll just keep on polishing it off every so often!
Cheers
Ben

Cheers Ben Why not give it a light dusting of that Zinc primer, it's easy enough to remove if you need to and it won't go rusty? |
