Make a small stage with a Block, 2 Conveyor Belts (going towards the block) and one Conveyor belt above the block going away from it. Set the sandbags to high and have a blast.

I use Bowser for this method, personally. Nice wide swing on A and the Conveyor belts will bring all the Sandbags (along with the stickers and CDs) to you. Just have Player 2 standing on the block.

Found a video for this on youtube. If you want to check out what it should look like search for "CD Factory" on Youtube.

Cheers

Edit: You'll need to unlock Custom Parts A & B. I don't think you need C.
