HI BB,

Normally a wrapper of this shape would be formed over a wooden former made to the inside dimensions of the required shape..

I hope that makes sence, using a set of rolls would make it very difficult to end up with the correct dimensions.

So, make a former out of a hard wood if possible, anneal your copper that has first been cut out to the required plan shape, and after annealing, gently hammer the copper round the former.

You will only be able to go a small way round the former before the copper will require annealing again, don't force it, you are likely to end up with it cracking.

Hope this helps,

Regards

Lofty

Hi Billy

Just done the same, did the first bend in the rolls, the second free hand using the end plates as formers. The copper must be kept well annealed then it bends like paper. Judicious taps with a planishing hammer gets the nice tight fit you need.

Keep on bashing.
