AdmiralDonSnider Posted June 24, 2013 Share Posted June 24, 2013 (edited) I have cast my own hardened lead media (10% antimony) using moulds that allow me cast multiple balls, but which leave quite a residue on the balls, which has to be removed somehow.Here you can see the media: http://www.amateurpy...d-media-moulds/ Do you have any ideas how to deburr the balls best? With soft lead I would just follow the suggestions of fellows and let it deburr themselves in the mill, but that won´t happen with hardened lead. But deburring every single ball seems tedious. I will take the effort, but want to do it the fastest possible way. Any ideas? Edited June 24, 2013 by AdmiralDonSnider Link to comment Share on other sites More sharing options...
Bobosan Posted June 25, 2013 Share Posted June 25, 2013 Since they are already cast, cut flush the sharpest sprues and let them deburr in the drum without chems. I don't believe the remaining high spots at the circumference will be a problem during milling. Link to comment Share on other sites More sharing options...

dan999ification Posted June 25, 2013 Share Posted June 25, 2013 I cut mine out with scissors, squeezed each one with pliers.After a few hours milling they are round enough. I had the time but you also need the forearms Dan. Link to comment Share on other sites More sharing options...
schroedinger Posted June 25, 2013 Share Posted June 25, 2013 If they got sharp eges or spike points, run em in the mill with normal sand, to smoothen these out, the run a couple hours witchout sand or any chems and then maybe again with some sand to make sure everything is smooth. If they aren`t 100% round, that doesn`t matter, the ball mill will do this over time. There aresome applications where pyramides or short round rods are used in a ball mill. They get round after some time Link to comment Share on other sites More sharing options...
Algenco Posted June 26, 2013 Share Posted June 26, 2013 I bet they'll still round out in the mill Link to comment Share on other sites More sharing options...
Hoppy Posted June 28, 2013 Share Posted June 28, 2013 I bet they'll still round out in the mill Yup!
