Hi all,

I'm currently approaching completion of my 1st locomotive, a 5" Hunslet to the Don Young design, but try as I may, I have not been able to form the brass cowling that wraps around the rear of the firebox backplate / outer wrapper joint. The cowl is a 2" wide brass strip in half round section and is curved through a 17 1/2 " diameter for 180 degrees, with the remaining legs on either side continuing half round but straight in order to cover the vertical joint.

I hope that makesense!

I've tried clamping sheet brass between 2 formers and heating/beating, but I still end up with creases. I've also tried forming a half round srtaight section and coaxing it around the radius, again to no avail. Pressing seems to be the answer, but I don't have the means or wherewithall to machine a set of dies.

I realise that the cowl is purely cosmetic, but as it adds immeasurably to the appearance, I would really appreciate some advice as to how approach this task before I ruin any more sheets of brass!

Many thanks,

Brian Brown
