Hunk of junk 2x4 cut into a couple of pieces to make a bead breaker. Two pieces for skids to keep the rim and rotors off the ground, one short piece cut at an angle for the 'wedge', a long piece (like 3') for the lever. Use a door jamb, wall, whatever; for the fulcrum point.
Three long tar/tahr/tire/tyre spoons. Jug of Ru-Glyde (NAPA), some split vinyl tubing for rim protectors (optional after practicing on someone elses wheels

)
Set of old wheel bearings, seals/shields removed, and degreased well. Combine these with the wheel, a couple of chairs, and the axle to balance. Basically this is a frugal Marc Parnes balancer. I dare say I can get balanced to < a gram with this setup.
