You'll need a 4x4 for the base, some scraps for the pad block and legs, a piece of all thread (I recommend 1/2"), two nuts and a washer and four wood screws. I also recommend that you use wood that's as dry as possible or cedar for the base, as wet wood can split when drying. I had used pressure treated wood for a couple but have replaced them due to concern for chemicals used as preservatives. If you wanted to use pressure treated wood for a garage setup, that may be okay, just be careful to clean up the sawdust and wear a mask when doing the work. The schematic shows the general principle of how to put together the business end, the "pressing mechanism".
