Had to replenish my stock of Lyman/RCBS type top punch blanks so I thought I'd post a video of the first step. The last time we ran these we had to change tools three times for each part. With a gang tool setup that we made several years ago this time all we had to do was operate the air valve to clamp and release the part and catch the part as it was cut off.
The second step - making the other end of the punch to be a specific caliber and flat faced or cupped - is done on a manual lathe.
Here is the first step
Here is the resulting output
Here are better shots of the tool holder setup. Everything is anchored firmly in place, no tool changes. Fast and accurate.
