Lubricants For Redrawing Shells.
For redrawing aluminum shells use a cheap grade of vaseline. It may not be amiss to add that the draw part of the redrawing die should not be made too long, so as to prevent too much friction, which causes the shells to split and shrivel up.
For redrawing copper shells use good thick soap water as a lubricant. The soap used should be of a kind that will produce plenty of “slip.” If none such is to be had, mix a quantity of lard oil with the soap water on hand and boil the two together. Sprinkling graphite over the shells just before redrawing sometimes helps out on a mean job.
