SD45elect2000 Posted December 17, 2022 Share Posted December 17, 2022 I'm doing a BUNCH of them. just wondering what the group thinks is a correct color. I have a LOT of different Alclad colors like copper, pale hot metal, exhaust, steel etc, as well as lots of other stuff.Randall Link to comment Share on other sites More sharing options...
Ratch Posted December 17, 2022 Share Posted December 17, 2022 If you paint one colour it will look painted. Think about what collector rings are made of and what happens to them Firstly they're made of metal, so a metallic steel or gunmetal to start with. They get hot, so discolouration occurs, maybe a transparent or metallic blue washed over. Then they rust, so careful dry brushing of various rust shades, not all over but in selected areas. My 2 pennyworth. Link to comment Share on other sites More sharing options...
SD45elect2000 Posted December 17, 2022 Author Share Posted December 17, 2022 Ratch got me wondering now just exactly what these are made from. Some metals don’t rust, some do. Most kit instructions I’m familiar with say to paint them bronze or copper but Isuspect they are either cast iron or stainless steel. Link to comment Share on other sites More sharing options...

SD45elect2000 Posted December 17, 2022 Author Share Posted December 17, 2022 That’s just what I need, looking forward to the photos , I have no access to RAF machines here. If I did I wouldn’t hesitate to answer my question.i would like to know what they were made from .Randall Link to comment Share on other sites More sharing options...
paul71 Posted December 17, 2022 Share Posted December 17, 2022 Hi rodI've picked a few different ones out so that you can see how they differ from each other even on the same aircraft at times ,they might be useful to you as some sort of reference, I've not altered the colours at all its how they were taken on the day I've only cropped them so there not so big and focus on the exhaust area for this thread,but as you say there is so many factors that can alter a picture as you take it let alone how you have your monitor set and how our own eyes see the colour when you look at them later on, it can only be a guide in the endits down to what you are happy with when its finished Link to comment Share on other sites More sharing options...
paul71 Posted December 17, 2022 Share Posted December 17, 2022 Hi randallI'm lucky one of my passions is second world war aircraft and there's a lot of museum's to go to some just have a few bits that have been found locally then there's the big ones like duxford, sadly I've not been able to get to any for a few years or any air shows.I've only put a few on so as to not overload people with pictures of the same thing but if there is something you want to look at better just ask i can always go through my pictures to see if i have it and post it for you, not all my pictures turn out good but with digital cameras it don't matter that much these days,hopefully they will help you as a reference to look at and a starting pointpaul Link to comment Share on other sites More sharing options...

peebeep Posted December 17, 2022 Share Posted December 17, 2022 If not being too cheeky I would still love to see pictures of radial engines and metals used on the engine covers. To kick off: Link to comment Share on other sites More sharing options...
dogsbody Posted December 18, 2022 Share Posted December 18, 2022 On inline engines, like the Merlin and the Allison V-1710, The forward outlet pipe would be heat-stained. Those to the rear of that one would be grey-stained by the TEL ( tetraeythyl lead ) that was added to the fuel to delay pre-combustion in the high compression engine cylinders. You cab see the stains on the undersides of Avro Lancaster wings as well as on top on the wings.As for radial engine exhaust rings, look for photos of restored flying examples. Some sre shown earlier in this topic. The RAF did use black paint ( a kind of stove enamel type ) to cover the glow of hot metal on their night flying aircraft, to help hide them from German nightfighters.This diagram shows how/where the heat-staining occurred on Bristol Radials:Chris Link to comment Share on other sites More sharing options...
SD45elect2000 Posted December 18, 2022 Author Share Posted December 18, 2022 Wow great pics. So, they are copper then. Randall Link to comment Share on other sites More sharing options...
peebeep Posted December 18, 2022 Share Posted December 18, 2022 Wow great pics. So, they are copper then. They are not copper, it's heat staining, usually steel alloy. Link to comment Share on other sites More sharing options...
SD45elect2000 Posted December 18, 2022 Author Share Posted December 18, 2022 I think I can duplicate the heat stains . A layered approach like Ratch suggested is probably the best. You can do a lot with the Alclad paint. Maybe a base of copper, with small amounts of white aluminum at the edges. Then a dirty wash over the copper. it will be fun to play with it a bit. I am building a Blenheim so I have a good reference above. I can’t wait to see the results.Randall Link to comment Share on other sites More sharing options...
