Here's what Star said in their original instructions:
INSTALLING MACHINE
In order that you may have the correct position for reloading, you should build a bench by using a board 4 feet or more in length; about 2 inches thick and 12 inches wide, using 3 or 4 legs long enough to make the bench about the same height as a chair. In the center of the bench build up a portion 5 inches high, making holes in the top for the loaded shells and fired primers to drop through into trays set under the reloader and on top of the bench; then bolt the reloader down on the top of the raised portion.
The raised portion should extend out far enough to the left of the reloader to have room to set two trays containing empty shells and bullets.
This arrangement will leave room enough on one end of the bench for the operator to sit while reloading and should you have a helper, he can sit on the other end.
After you have your reloader installed and before trying to do any reloading, you should make a study of each operation. Before filling the powder magazine or putting primers in the tube, we would suggest that you run a few empty shells through, bringing the lever all the way down each time you insert and position a shell in the plate, and watch carefully each station so that you will know just what is taking place, at the same time you will learn why there is a loaded shell at each stroke of the lever.
