It's pretty straight forward. Use a spring from the collator to the drop tube just like normal. For 9mm and 40sw brass, or sizing pistol bullets (9mm-45acp), the DAA large spring and my large adapters will work. For 45acp brass you would need the DAA output chute spring, which is 13.5mm ID, and my extra large adapters.
Print out the "APP_Drop_Tube_#3_#4_Tube_Adapter". This will connect the drop tube to either the #3 or #4 (two largest) plastic tubes that come with the APP. From here you are just setting up the APP the way you would normally. You can cut the tube down to be shorter if you want, which is what I did.
There is a pic of my setup on page 79. In the pic you will see I also have a "APP_Offset_Connector" on the APP press. I came up with this and use it primarily for sizing 45acp bullets, because it gives me more clearance between the tube and my modified handle. It will not work with .45 brass (they will get hung up), but I assume it would with everything else.
Edited to add:
Here is the DAA output chute spring. It is larger then the DAA large spring by .5mm, and is 4 feet long, so you can cut it up in to whatever length pieces you need. I mentioned this before, but if I were to buy springs again I would just get the small DAA spring and this output spring, and skip the large one. This one will do everything the large one does and more. Who knows maybe you can find a use for the chute too. lol
