King, Mec will make the "short" press for progressive presses. SS presses are done by the owner because it's so simple. Actually, what Rick referred you to will work, but some of the wood parts are unnecessary. That top piece screwed to the other one isn't needed. You're just trying to raise the shell in the last three stations. And the bottom wooden piece should have extended over to the station under the drop tube. If you go here
