Thursday’s post Update on Japanese 99 magazines

This was going to be a library post but I felt that this was a little more up to date for the on going projects. We have finished the next phase of design of the Japanese  99 dies. If you might have forgotten we had a few problems with are original die design with it shearing the sheet steel as it went into the female die.

This die is a spring loaded die that will pick up the sheet metal after it has been located with dowel pins an holds it between the two dies causing the sides to bend inward up until it reaches the base at which time it presses in the groves into the sides. Here are the solid model designs.
