oz rb fan Posted November 3, 2019 Share Posted November 3, 2019 i am working on an early MK1f beau and was wondering what colour for the exhaust ring...i know they were made of stainless steel but were they bare or painted? paul Link to comment Share on other sites More sharing options...
Heather Kay Posted November 3, 2019 Share Posted November 3, 2019 I’m pretty sure the collector rings remained unpainted. I found a Beaufighter MkI photo on the IWM collections site, but I can’t get the link to share it presently. It shows a MkI Beau in flight, and the rings are definitely not painted over.

lasermonkey Posted November 3, 2019 Share Posted November 3, 2019 I took some colour screen grabs of Blenheim collector rings and posted them in the link above. That should give you an idea of how they looked new. In some of the pics you can see how the collector rings start to change colour from the heat. Cheers, Mark. 1 1 Link to comment Share on other sites More sharing options...

rossm Posted November 3, 2019 Share Posted November 3, 2019 Post no.8 in this thread is a good start https://www.britmodeller.com/forums/index.php?/topic/32192-bristol-engine-collector-rings/&tab=comments#comment-346017 I'm sure there was a thread that had a diagram of how the various bits fitted together which helped make it clear which bits got hot but I can't find it - I thought it was the one above. 1 Link to comment Share on other sites More sharing options...
Vanroon Posted November 4, 2019 Share Posted November 4, 2019 Heres that drawing which shows the two construction methods. The Mk.I used the left hand method. G 3 Link to comment Share on other sites More sharing options...
nsmekanik Posted November 4, 2019 Share Posted November 4, 2019 Some collector rings were painted black, here you can see some of the paint worn away A color pic and one in Italian service with unpainted rings And some Lysander pics which should help give a good idea what they look like You will notice the foremost ring remains aluminish as it doesn't get as hot and some Hurricane exhaust which is made of the same material 1 Link to comment Share on other sites More sharing options...
Graham Boak Posted November 4, 2019 Share Posted November 4, 2019 Later in the war heat resistant paint was developed in white and black, largely to cut down the glow down hot metal. This is what is visible on the 1944 Beaufighter and presumably on the Mediterranean one too. 1 Link to comment Share on other sites More sharing options...

I grew up on a farm where the kitchen stove was wood burning and the heater in the old back kitchen and the furnace in the cellar were wood burning, too. They were all painted black that never came off. Chris Link to comment Share on other sites More sharing options...
Graham Boak Posted November 4, 2019 Share Posted November 4, 2019 Let's say adopted? No idea of its origins. However from the Beaufighter photo this did come off. 1 Link to comment Share on other sites More sharing options...

The first reference I had of it was of its use on Stirlings where it had to be regularly re applied which was not a popular job!

Graham Boak Posted November 5, 2019 Share Posted November 5, 2019 Things are not slapped on military aircraft by chance; they are approved by somebody, ordered by somebody, paid for by somebody, delivered by somebody. They don't happen to come in just the right colours (even black and white) just by chance. However, such records as are kept don't include inventory levels and what was delivered by which truck on which day, so the chance of finding out on the squadron level is slim. Somewhere in the NA is a file covering heat-resistant paints: maybe it is mentioned in a book describing what good work paint company X did for the war effort if such a book exists. 2 Link to comment Share on other sites More sharing options...

rossm Posted November 5, 2019 Share Posted November 5, 2019 And from Paul Lucas article on the Sunderland in MAM a while back Admittedly talking about white but definitely anti glow paint as an official stores item. 3 2 Link to comment Share on other sites More sharing options...
