Re: Gibson LMS Compound

Thanks Tim :) Can't decide which of various threads to ask this question on so here goes - I wonder what people think about painting the chassis with IPA alcohol used (drizzled about with a paintbrush) as the final cleaning agent? Photo taken a couple of hours after I did the tender chassis. Loco ch...

Re: Brass preparation for painting

Re Allan's post just above, what I don't get is this: we use phosphoric acid flux....which makes crud...we then use phosphoric acid.... to get rid of the crud!(?) There seems to be more traffic on this thread than where I posted this idea, a citric acid "pickle" to, I assume, do the same t...

Re: Brass preparation for painting

Andy that is useful to know, thanks. But it is the preparation (specifically, the cleaning) of the brass model, before the application of primer, that was my concern just at the moment. Is your recipe using Cillit Bang and Shiny Sinks still your preferred one? No one else has raised any further thou...

Re: Brass preparation for painting

Looking for advice on this subject (it's the aspect of modelling I get very little practice at, being so slow) it was a bit disappointing that this thread is so brief! The thread by Allan Goodwillie on making locomotives has a useful section on this page https://www.scalefour.org/forum/viewtopic.php...

Re: Bachmann B1

It's always such an irony - we go to great lengths to make the brakes as close as possible to the wheels yet not touching at any point of the suspension/sideplay travel, then to even greater lengths to get pickups on that touch at every place the wheel might go yet are invisible and do their job.

Cheers Philip - I think it's all in vain unless it's visible on the end product which depends on one's sight! - and viewing distance, lighting, etc, so when I paint it I'll make the colours lighter than they should really be.

Thanks for the comments! I couldn't attach these pictures that came up on a Google search for "atomiser" to the last post, here they are. The diagram gave me the basic idea of how the four pipes relate to the lubricator box. I've sorted the tender height a bit better now. Mark's comment pr...

Mark thanks for that thought - I assume you mean the tender front, not back. I'd thought the RHS was correct (I know the LHS isn't) but checking photos I see the tender chassis valance thingy (I don't know correct words) should line up with the bottom of the one on the loco, not the top as I've got ...

Re: Gibson LMS Compound

There are some problems that I can't change arising from having bought the kit partly built, tender complete. The loco frames seem to sag slightly at the cab. Whether that is the reason I don't know, but the bottom of rear footstep is too low - it should be above the level of the brake rigging - and...

Re: Brassmasters Blk5 45232

No atomiser above the platform in front of the lubricator on the loco as preserved at the museum in 2013 Dave, and none I can see on the RHS. But there's no lubricator on the RHS at all. Pictures of the loco I've chosen to model in BR days show lubricators both sides, but plenty of photos from earli...

Wow :!: The idea of a tube 0.5 to represent the lubricator glands is really helpful.

Do you know about this? - the Compound lubricators had 6 pipes originally each side. I see you ...

It enabled me to make sense of the pictures that I took all those years ago that follow. I...
