Finally got around to snapping a couple pics of my Supersizer setup on the drill press table. It is so simple and quick to use....... one 4"-5" stroke of the handle, downwards, holds the case tightly for crimping. Just as quickly as the roll crimp is done I release downward pressure on the handle and a spring raises it, releasing the hull from the collet. No handles to screw and unscrew, just a quick downward movement and then upward.
Collets can be changed to accommodate any gauge, for resizing and then for roll crimping. Works so fast you can crimp several per minute. And, I like to work fast when roll crimping plastic hulls. Seems to work better for me when the crimping head stays warm.
