Great stuff Bill! The cylinder looks a lot better.
If you need to bend sprue to shape for other jobs, depending on size/angles etc, a pin board often helps. This is basically a sheet of balsa or similar, with a sheet of paper on top, which has the shape(s) drawn to scale. Where a bend is needed, insert pins, then anchor the sprue at one end, then bend it around the pins to form the shape, keeping it under tension. Apply gentle heat, maybe from a hair drier, then cold air. The sprue should then retain the shape, and can be trimmed as required.
