Threaded Kettlebell Handles
Back around the turn of the 20th century, mass-produced weight lifting sets were beginning to catch on in the USA and Europe. Although they no longer included true bells — hollow spheres that could be filled to the desired weight with sand or lead shot — people still called them as such: barbells, dumbbells, and kettlebells. The weight came from standard iron weight plates that were similar to the ones commonly used today.There were two ways that early equipment manufacturers met the demand for adjustable kettlebells without actually making hollow spheres (or bells).
One, they made kettlebell handles for dumbbells. These handles attached to the handle of an adjustable dumbbell.
But the second way was to provide threaded kettlebell handles. These were extremely easy to use; all you do is pop some weight plates on the handle and tighten two locknuts. It’s easier than setting up an adjustable dumbbell.
Threaded kettlebell handles and their weight plates superficially resemble traditional kettlebells. Although they’re probably not as comfortable and useful as regular kettlebells or kettlebell handles, they’re better than nothing. Athletes would set one (or two) up and use them for dynamic overhead work or Olympic-style lifts.

So you have some old weight plates (dumbbell plates or barbell plates) lying around collecting rust? Why not use a threaded kettlebell handle and turn those plates into a kettlebell? Making a kettlebell was never so easy!
