Sometimes we will encounter items in our workshops that are a little bigger than we bargained for. An engine block, an anvil, or a particularly substantial machine tool. Lifting these things may be possible, but doing so risks injury, perhaps a hernia or worse. For these moments a particularly well-appointed workshop will include a small crane, and [Workshop from scratch] has posted a video that we’ve placed below the break showing the construction of a particularly nice model.
The fabrication of a crane is not in itself a difficult task, in that most metalwork-minded readers could probably make one. What’s appealing about this video is the sense of gratification at watching metalwork being done well, and that while he does use a bandsaw and a drill press there’s not a lot in the video that couldn’t be done with more basic tools. The result is a handsome item that is probably better than many commercial offerings, though the gut feeling here is that the pivot points would have been better made with a sleeve and pin rather than a threaded bolt. The lifting effort comes from an off-the-shelf hydraulic ram.
Cranes feature here surprisingly rarely, but at least we’ve brought you a balcony crane.
