This is a little of of the subject, but is a modification nonetheless. I like having the ability to move my equipment (not the machinery) around to where I am working in my shop, then get it out of the way when it is not in use. To do this, I put casters on everything that I can to facilitate movement. The one item I have pictures of is my hydraulic press. It does't see too much use, but it is easily moved about when it is. Common inexpensive hydraulic press: The base. Two pieces of angle iron were cut and welded to the base to keep it rigid during movement. The ends of the "legs" were drilled and casters from an old shopping basket (picked up at the scrap yard, not the grocery store!) were added. This little mod took about an hour to complete, but the mobility of the press is a very welcome trait for this otherwise hard to manuever item. It is top heavy, but with deliberate movement, it is very stable on the casters. A clear path is essential for safely moving it about. In hindsight, the base could have been bolted rather than welded. This may be of benefit for someone wanting to do this mod that doesn't have access to welding equipment. Additionally, all of my tables and benches are on casters, and they are moved where the work is when needed. Fewer steps back and forth seem to keep things more enjoyable, at least for me. It also helps for housekeeping purposes to be able to get things out of the way for a quick and thorough clean up.
