Hi all,
I really should have joined a forum many years ago. I started building my Martin Evans B1 back in the early 90s. Divorce and other things meant I left the project alone for a long time. So I promised myself I would start again when I felt more settled. I was at a vintage steam rally last year in Cranford, Northants and a lovely old chap had brought along his part built 5" Jubilee (I think). I was inspired! So I have started up again and de-mothballed my engine. So, some of my future questions may be a little school boy for some of you more seasoned builders but its good to know I have somewhere to get advice? Have I even posted this in the correct area?

Jinks?
I have e
found out the hard way that dear old Martins drawings are, lets say, a bit liberal in dimensioning Can i suggest that if you are not at the trnder stage yet, a visit to the NRM and a day pouring over works drawing with planty of pics will not be wasted. AND if either 61264/61306 gets anyywhere near you that pics of their tenders will be a great help, esp the front and locker arrangements. I have found out the hard way that B17s had at least ( to date) diffrent arrangements with their GE tenders, resulting in me being on my third body and second chassis Triggers Broom eh?
Any questions and believe me from the ones i have put up over the years the 'elders' are a very patient lot lol
Keep posting on your progress
Best Wishes
Ron

Or, if you're like me, you'll have no interest in the different tenders that may or may not have been attached to one or another engine. If a rivet counter turns up and says that the original was not like that, you can invite them to explain at length and make their day.

Wilf,
i agree with the rivets, but Taking workmamshop as read, i look for,does it look like what it purports to be, and if so is the painting correct. There is a lovely B1 coming up fpr sale on one of the sites ,but the csabside mumbers are not quite right. My teeth started to itch quite badly!! BUT that is my bette noir.
I am looking forward to someone pointing out that my tender is asymmetrical, let them rant on and then i get the pics out and do a Bill Carter on them. Likewise there will be a dent in the RH cylinder casing WHY? because the picture i have of the loco has one, if only to annoy them lol
Seriously to build a loco( again great workmanship) and to claim it is a XYZ yet not have the correct cylinders, a fictitious number yet the outline is the same is akin to putting a Porsche body on a Skoda chassis....... a Porsche it aint!!
But at the end of the day it is their loco and they can do with it as you wish, it just isnt ( as James Brown used to sing ) My bag

To build anything is an achivement, to build it to please anyone other than yourself is a waste.

Like Mr Jinks, I have an unfinished 'Springbok'. Bought some years ago (12 I think?), to be a quick completion as it was not far from finished. Not much I could do about dear Martin's errors, but more so with the previous builders. For instance he did not allow for the 1/16 inch gasket for the cylinders, therefore all other parts of the motion were not in alighnment. I only found this out a few weeks ago, wondering why everything was a bit tight! Even the boiler, which I believe to be by the late great Ron Chambers, has two extra bushes on the smokebox end for the water pump and injector, the original builder using the backhead bushes to secure his own design of the firebox door! These are now blanked off with plugs with very thin hex heads, but will still be visible unfortunately. As for the tender, well, it is what it is, and I can live with it (at my age, haha). Now all I want is to get it finished and into steam. I'm not too fussy about the number of rivits, etc, although I do like them!

I'll be using a flange sealant when I seal mine up for the last time. It may be a solution for you to do the same? regards Pete |

Hi Jinks
Welcome to the forum, I'm confident that any questions that you may pose during your build will be answered by a member of this forum, in fact you'll probably get a few suggestions. good luck with your B1 build.
Regards
Pete

I've already fitted the gasket material, but, as I said, the motion plate (on one side) was then tight against the frame, and the other side was too far out so I had to machine some metal off! The original bodger, sorry, builder had also cut away part ot the connectiong rods on the inside, where they fouled the front of the coupling rod (this lack of clearance is a known error), but I soldered a piece of steel into the recess, as, with the gasket in place this no longer fouls!

cool.. happy to hear you have it sorted Geoff, yes it's always a minefield finishing a model that someone else started. I've been through that with 4470, never again, I still need to renew the superheater as I think it's leaking. Far to busy with her big sister to play around now, one day perhaps, she makes a nice mantelpiece ornament though...  Pete |

Have you got the ME series on it?. I used them as a basis for the B17, If you want any scans let me know

My latest conundrum is how to machine the smokebox saddle! The smokebox is 6.25" dia. I am relatively happy to fly cut this on my vertical mill but how on earth do you hold it? My lathe (Warco 918) doesn't have enough swing to use a between centres fly cutter and my mill doesn't have enough travel to do the whole job in one direction. Any advice would be gratefully received |

Why not just file it in the bench vice with a half round file? But first make the smoke box. Keep offering the smoke box up to it. Wherever it rocks, file that bit off. Keep going until it fits. Then stop.

When I did my saddle I double-sided some aluminum sandpaper to a tube of the right diameter. It did the job but to be fair, the saddle arc was pretty close, to begin with, just needed the flange thinning down.

Thanks guys. I was indeed looking to use a drum with emery paper but I am going to try using a fly cutter in my mill with the saddle mounted vertically. The biggest problem is finding a way to hold it in place
