Randy,
The link below will take you to 16ga.com and the thread in which it was first posted. Scroll down and you'll see the crimp head as well as paper and plastic hulls done with same:
http://www.16ga.com/forum/viewtopic.php?t=7496&start=0It was also posted here at DoubleGunShop by me at about the same time (early June) .....if you look back several pages in the earlier thread topics. The head as you can see is pretty small and came in the various gauges. Lyman also made a hand crank machine to hold these heads, though a drill press works just as well or better, IMO. Go through all pages of the 16ga.com thread linked above and I believe you'll see the larger machine pictured. If it's not there, then it's in the earlier Lyman roll-crimp thread on this site (c. early June, 2009.) I distinctly remember someone posting a picture of the machine. Hope that helps....
I've still an extra (unused) 12 ga. Lyman head available, should you decide you want one.
