This is the miniature version of our highly regarded Maelstrom spinner! This spinner is made from brass and stainless steel. The ring is what makes it special. We use a 10 ton broach to generate the teeth on the ring. We then shrink it in liquid nitrogen and insert it into the housing. There is no adhesive, screws or welds holding it in place. Pressure from the shrink fit holds it firmly in place. We have chosen the same r188zz abec 7 hybrid ceramic bearing for the Mini Maelstrom that we use in the standard Maelstrom. We use the same caps on the mini that we use on the full size Maelstrom. This version uses a few dollars less material but is a little more complicated to make compared to the standard Maelstrom. This is why the price is the same for both versions.
