I haven't in a while, but I used to have a "station" made out of a 15"(i think?) car rim mounted to a table. Split garden hose lined the bead on the "up"side, making a perfect platform to hold the MC wheel being mounted. The MC wheel was secured to the platform using a threaded rod, big washer and wingnut.
some soapy water and momentum makes getting the first bead onto the rim easy(just slam that sucker on there). Then you only have to deal with the second bead with, as IKARUS404 says, tire spoons and lubricant and patience.
think i've seen a few youtube vids on balancing, but again i haven't done it recently enough to verify any of them.
