Don't use a tool for anything other than its intended purpose. Using a wrench as a hammer may seem like a quick fix, but it may cause damage to the tool, the project, and possibly yourself. Remember, always use the right tool for the job.
Use caster sets to keep your major tools, even workbenches, portable. Wheeled tools and benches will allow you more flexibility, and will let you reposition for specific jobs like ripping long lumber or for taking advantage of natural daylight.
