Painting and lining

Sorry to go back to the topic last week of flux, but I regularly solder steel so rust is an issue for me. I use Carr's if its stainless, but Bakers Fluid if it isn't. I then wash and treat immediately with Jenolite which stops the rust pretty well.

My confusion is that folk seem to be saying that paste flux is phosphoric acid, but I thought Jenolite was phosphoric acid too?

They use phosphoric acid as a base for rust cleaners etc. I do not think paste fluxes are phosphoric. But the carrier is a soap base. It is hard to clean off. It is very good at hiding in small gaps and leaking out later. I have even pressure tested plumbing systems and then running for a week before it has let go in joints.

Hi Peter. That's replicated itself in model building for me. Joints which looked sound when made have broken own later - probably because I'd not put them under enough stress when initially built but experience says that safety flux is less forgiving. If it's gonna go it'll go.

The flux can get like green lime scale. If it happens inside a joint you cannot clean it, and it slowly desolves hence why you get the reaction spreading from joints.

On the topic of paste fluxes, I was re-reading an old MRJ (you know the magazine, the one apparently disliked over on the 'other side') no 161 when I came across a letter by someone called Brackenborough, you may have heard of him. He stated back in Oct 2005 that these fluxes were his greatest problem, calling them "delayed action paint-strippers".

So if anyone still doesn't believe Warren then surely Mr B is authoratative enough?

Hi Warren,

I just kept looking and looking at these latest photos. The SECR loco's livery in particular is exquisitely executed. You do not have to divulge trade secrets of course, but how on Earth did you line the splasher tops of the Immingham locomotive?

Cheers Colin

No secrets really, the backs and bottom edge are free hand with a 00 series 7 miniature brush, the fronts are edged with the compasses. If the boiler had been made removable it would have been so much easier as then the backs could also have been edged.
I think a lesson for all GCR modellers, make the boiler come off;)

Warren, looking at the next to last photo of the Immingham I thought that the boiler came off and that you had not fixed it down correctly looking at the gap on the L/H side of the saddle.

OzzyO.

When I screwed the bogie on it pushed the boiler up, I noticed it after the photo also. I slackened it off and the boiler has gone back to normal position with no adverse effects.
It's soldered up solid at the cab end.
Well spotted:thumbs:

You're B*****ing about again, Warren. That's clearly the prototype reference pictures. Where's the model?

In truth the only give away is the track......

Magnificent!

Yup, the track is the give-away, unless, of course, Warren is using Photoshop and adding Peco track to the real thing to confuse everyone. Devious.

Need to eat a Thesaurus to find the right words for this quality of work. The guy even gives close-ups, you know the ones the rest of us avoid like the plague (unless you are Nick Dunhill and one or two others who build things like Bullieds).

Still, its things like this that give the rest of use something to aim for rather than stagnate.

Keep up the great work mate.
