More draw die experimenting

Well today I found it easier to make more dies and punches rather than make jewelry....
I started with a 3" diameter piece of 18 gauge sterling sheet. Punched it through 5 dies, annealing between each step. Ended up with a cup(shot glass) with a round bottom, 1" in diameter and 2.6" tall. Counting anealing time it took less than 20 minutes to go through all dies. The thickness at the top rim is 1.2 mm now, a 20% increase.
I don't have a digital camera so it will be a few days before I can post an image.
All of the dies for this can be used on the Original Bonny Doon press.
(one doesn't need a larger aperture or more powerful press).Anybody interested in this kind of pressing?
