Corbin announces the world's first practical, true sprueless ROUND BALL SWAGE for home use! Most swaged round balls are really multi-faceted polygons, with dozens of tiny flat surfaces applied by passage through a "meat grinder" helix. The BSK-1-S Ball Swage Kit consists of two dies that make precision, round balls of exact weight and spherical shape, in two quick operations.
The first die is a CORE SWAGE, which produces a lead cylinder with rounded ends, of a weight that is approximately 1 grain heavier than the final ball. It accepts lead wire, cut from a spool with a Corbin PCS-1 or PCS-2 core cutter, or cast in a Corbin CM-4 or CM-3 core mould. The diameter of the wire is not critical, so long as it fits into the die and isn't so small that a sufficient weight projects from the die.
The core swage die adjusts the weight automatically by extrusion of surplus lead from precision bleed holes in the die wall. You simply set the position of the punch holder, in the Corbin S-press, Corbin Mega-Mite, or Corbin Hydro-Press, so that the lead weight is about 1 grain heavier than the desired ball (information on the proper weight comes with each set).
Then, after making a quantity of these precise cylinders, you change to the ball swage die and reform the cylinder into a perfect spherical shape. Rotate the ball a quarter turn so the parting line is vertical and press the die together again, and you have a true round ball.
Each BSK-1 Ball Swage Kit comes with specific instructions giving the formula and the calculated exact weight of the ball, plus the suggested weight for the finished core.
The BSK-1-S Ball Swage Kit is available in any caliber from .22 to .54, for the Corbin CSP-1 S-Press. The BSK-1-H Ball Swage Kit for the Corbin Hydro-Press, Hydro Junior, and CSP-2 Mega Mite Press can swage nearly any size ball up to an inch in diameter. Prices may be seen at http://www.corbins.com/prices.htm. Use your "find' or "search" option to look for either BSK-1-S or BSK-1-H in the text of the price list.
