The thread start itself would though have to be able to travel in any direction, but if meet with a thread going in one direction, it will push a leaver and push over the cam and thereby the thread, ensuring that the nut can only be threaded on in that direction. Driven by an internal cam that is controlled by a leaver at the thread start. One could also make the thread into many smaller sections that are able to rotate. Though, how useful that is in practice is a different story. It would though need its threads to have a pivot at their start that the rest of the thread then follows after. Posted in Parts Tagged bolt, fidget, machining, threaded Post navigation Sadly it is a fading form of craftsmanship, rendered mostly obsolete outside of hobby projects by CNC machines. A handbuilt V10 engine and a pneumatic hexacopter model are just two examples of what’s possible with enough skill, knowledge, and patience. It’s possible to make incredible parts on a manual lathe. While this is a one-of-a-kind fidget toy, have any of our readers seen a bidirectional bolt or lead screw in the wild? We can imagine that the ability to move two nuts in opposite directions on a single lead screw might have some practical applications. Although the bidirectional nut doesn’t move as smoothly as the other two, it can change rotation and translation direction at random. Due to the large pitch and careful machining, all three nuts will spin down the bolt under the force of gravity alone. First left-hand and right hand threaded nuts were made, followed by a bidirectional nut. also machined three different brass nuts to go on the bolt with a fixed cutter. ![]() Instead of a fixed cutter, he used a trimming router mounted on a custom clamp. ![]() It took four painstaking attempts to get it right, but the end result looks very good. Since this was all machined on a manual lathe, a dial indicator was required to maintain accurate spacing. The large pitch means that instead of a single continuous groove like a normal bolt, ten separate grooves need to be cut for each threading direction to cover the bolt surface. The bolt is an M42 size with a 40 mm pitch, with grooves cut in both directions to allow left-handed and right-handed nuts to be threaded. But that doesn’t mean they can’t be used to have a little fun, as demonstrated by who made a bidirectional bolt as a machining exercise just because he could.īoth videos after the break are in Russian, but the video and auto generated subtitles are enough to get the main points across.
