    One way that I have found to be successful is the  following: 

    1. Decide on the outside diameter of the donut and make a 1/2 sphere
    conforming to this dimension.  Make sure you drill a small hole in
    the centre of the disc before dombing.  

    2. Place finished sphere, domb facing up in a pitch bowl. 

    3. At location of predrilled hole, proceed to deform metal with
    various sized ball punches (small to large) down into the pitch until
    desired shape has been achieved but making sure to anneal adequately
    during process.  

    4. Turn donut over in pitch bowl and work from back if necessary. 

    Hope you find this explanation adequate and look forward to reading
    other suggestions.  Have a good one from David Tranter in sunny Cape 
    Town, South Africa.  aurum AT worldonline.co.za.
