A tip for the budget versions pictured above – grab a couple of zip ties and tie one around each leg. The excess straight part that sticks out can be directed to stick out between the legs and act as a pointer/guide for truing the wheel (if you get what I mean). If I wasn’t so lazy I’d draw a pic.
I’ve built plenty of wheels for bicycles over the years and recently laced up a couple of motorbike wheels too. I have to say the motorbike wheels are much easier due to the hub design (spokes are guided in the right direction) and the strength of the rim as well as having disc brakes. Building up a skinny little racing bike wheel can be a real pain because the rim can be contorted so easily by the spoke tension and the tolerances are much finer with a rim brake.
