exhaust collector rings

There is a deal of variety to colouring exhaust collector rings.

There is a recent article in BM somewhere where the construction of two types of Bristol collector rings was discussed. This matters, for one had a fairing which didn't discolour as much as the nickel-steel main collector or individual header pipes.

Found it!

I like to paint mine with jet exhaust, then dry brush with burnt metal and gunmetal mixes. The hedgehogs I'll commence with burnt metal and tone with matt cockpit black with a little beige/tan for lead ashing then pick out details like heat paint or fairing rings as your subject requires.

Good luck with the advice which I'm sure will be forthcoming.

My Hampden build was odd for this reason. I have looked at a variety of pics and ended up doing a mix of gunmetal and antique brass. I think I didn't use enough of the latter and the Engines look like they are just out of the factory! As I have said in another thread, I am not good at ageing or weathering.

I've painting mine metallic gray and then over sprayed flat black for my beaufighter, I will use some metallic coloured weather powered around it to give it a weathered look to it.

Doing some research on collector rings, I found out that some were indeed painted black, this was due to the metal heating during flight and would cause the metallic coloured rings to give out a glow, which was very bad for night fighters. Hence they were painted black to try and decrease this effect.

I'll upload a picture of an engine once I've finished one, which will be in a couple of hours hopefully

Here is the RAFM Blenheim/Bolingbroke.

In contrast that of the Beaufighter X is painted black (no pix for this I'm afraid).

If painting a 'metal' ring, I use an acrylic mix of Revell Aluminium and Citadel Tin Bitz.

The bright coloured pipes(?) visible between the cylinders, is that part D12 in the Airfix kit? I ask since Airfix says the same seimigloss black as the rest of the engine, for part D12.

Part D12 is the induction ( fuel/air ) pipes to the cylinders, from the supercharger at the rear of the engine. The light coloured between the cylinders in the photo are the baffles that direct the cooling air around the cylinders. These are not include in the model. For that matter, the baffles have never been included in any kit that I have ever seen.

At the risk of stating what most already know, the collector rings started out as unpainted steel alloy which, unless they were actually painted at some point, would become discolored due to the heat of the exhaust gases. There have been many previous threads on this topic. One of the more recent ones can be found here:

I'm just about to paint the collector rings on my Blenheim IVF and was planning on using Tamiya Dark Iron as this looks close to photos of the real thing.

The other point I noticed from prototype photos is that engines on Blenheims appeared universally black.

would appreciate some advice on the colour of these.the airfix beaufighter instructions state matt black,which just sounds wrong to me;tamiya ,and others suggest brick red,red brown etc

When I built a Beaufighter about a year ago I discovered that the ones used by Coastal Command as in the new Airfix kit mostly had the collector rings painted black, but of course the paint would show ware after time if not repainted. If you are doing the Far East version then sorry I don't know if they were black or not, you are probably best asking the Beaufighter experts on that one.

If the Far East version had unpainted collector rings then like Vanroon says it is all explained in the earlier thread that he linked below, there even are diagrams and everything!

As far as unpainted collector rings are concerned I feel sure that they were not the copper or rust colours often given in painting instructions, but anything from silver up to a dirty lead colour with a dusting of powdery rust.

Novice suggestion; to get the colour of heat discoloured metal would a colour such as Hu56 washed with Humbrol Oil Stain wash do the trick? Sorry if this is wrong: just an idea.
