Hello everyone. New to the forum and trying to get some insight into metal spinning. Run a machine shop in Barrie Ontario and by necessity need to learn to spin simple end caps in stainless. Have done a few but having some difficulty with getting 90 degree bends. Always has a slight taper and not sure how to overcome this. I'm hoping someone might have some suggestions. Have not tried annealing as we are trying to keep the material from obvious heat discoloration. Doing these in 304 SS x .035" thick. Flat diameters range from 4" to 6" with 1/2" long skirt.
