I'm trying to locate plans or suggestions to make a large cabinet mobile. I saw an idea online (unfortunately I'm not able to locate it now) which involved using a long piece of all thread which when turned activates a set of wedges underneath and are concealed. When turning the all thread or threaded rod it will raise or lower a set of casters. Upon placement of the cabinet you can then turn the threaded rod and cabinet would lower.
