You can do most sanding by hand, using sandpaper, SB, Siaair, Abralon, Mirlon, or NEAT pads. The rougher sanding is harder, due to the nature of the roughness.
Use of a CAB or other device to insure the evenness of the sanding can be very helpful. Light, even pressure is best; it helps to insure the actual grit level of the pad is applied and reduces the amount of stock removed.
Use of water will help cut down on the toxic resin dust put into the air and which you will wind up breathing.
Compounds and polishes are much harder to apply effectively. A spinner is almost a necessity, with a a few exceptions , like rough compounds (Step 2, Crown Compound, Gel Scuff, as examples). You won't be able to get them to smooth the ball, but they can apply a rough version of what they usually do.
