Is it me? I am building the Project loco from the book and have started the boiler, It shows two pipes projecting either end. I have no idea how these are connected to steam ? I know I must have missed something in the build instructions!!!

I mused on this one some months ago, looks to me as though the manifold at the cab end is fixed to the two pipes you mentioned by nuts and olives. Depending which drawings you have, the later project book shows coned seats for the olives to sit in, on the rear of the manifold, the older version does not show the coned seats.

Hi steamboater
I built my 'Project' from a very old paper pamphlet style booklet, (I think someone may have copied it from a original) but was lucky enough to have some plans in A3 size as well. As my first loco I found it challenging and at times I too was a bit confused as to some of the parts and what went where but lucky for me I had some help from folks on this site and managed to piece her all together. I have run her up on air and she ran great apart from a small pin hole in the boiler which I am hopefully going to repair this week if my gas bottles are delivered. I would be happy to assist you if I can by way of photos or advice, I will be rebuilding her once the boiler is fixed and testing her on steam this time.

I am also building the 'Project' and was not happy with connecting the blower and steam pipe direct to the boiler as shown in the book.
So I took advice and followed someone else's example and put two 1/4" pipes through the boiler to act as hollow stays ( in place of the blower and steam pipes) and then fed the smaller pipes though the stays. It made them easier to fit and as they say "She steams like a witch"!

Hello Ace,
Any picture would be greatly appreciated, the last post from Bookworm seems very helpful, as I have heated and cooled the boiler more than one once! I am getting to the stage where any advice would not come amiss, thanks for the reply by the ay

steamboater I am re-soldering my boiler tomorrow (small pin hole in it) so will take some photos for you at each stage of the rebuild. How far have you got with yours mine was almost finished until it sprang a leak in the boiler and then had to dismantle it.  ace |

steamboater sorry about the quality of the photos, I have not got the hang of my new camera yet and can't seam to get the light level right. Anyway here are a couple of photos that might help.  .  The larger pipe is molded that shape to fit around the petticoat.  Now I am left with scrubbing the boiler all clean again, mind you I have tested the boiler while it was all put back together loosely and no leaks from anywhere and held 50psi for over 1/2 an hour. ace |

Hi Ace
That looks very nice indeed, been sometime since you've posted a picture and they're most welcome.
One small point, and it may not be a problem, I noticethat the blast pipe doesn't look vertical. Is that part of the design?
In my dealings with engines, mainly full size so it may be off the mark in this case, the blast pipe alignment is critical for steaming. The blower tube, blast pipe and chimney alignment together create the smoke box vacuum necessary to draw the fire through the boiler tube(s). If there is any misalignment or leak in the smokebox the locomotive's ability to make and maintain the necessary steam can be compromised. It may not have such an effect in a gas fired engine but I'd imagine that the 'scale effect' might be greater the smaller you go?
No critcism intended just an observation.
Cheers
Brian

Hi spurley
Yes the blast pipe is bent, must have happened when I re soldered the boiler yesterday. Saying that I have yet to clean (pickle) the boiler again so I will reset it after then.
Spent today designing and building a steam whistle valve to fit on the regulator will post a few pics later. I fancy having a small whistle on my loco. ;D

Many thanks for the pictures, much help with those, can I ask? But the book shows the steamchest and cover as two separate items, It could be the picture, but yours looks like one piece? Am I right? As this will save some work of course.

No problem mate, I have now cleaned my boiler and have just a bit of fiddling to do with the smoke-box as it appears not to want to fit back on now. I have to say that when making the cylinder and associated parts - time and patience will pay off, it did for me and I am pleased with the way it runs (on air) and the fact that I made it all from one solid block of 3"x3" brass to begin with. ;D
I will be uploading more pictures on the G1 site shortly of my progress.
