I am realizing now that from the video and photos you might have thought the entire white delrin part spins separate from the top but it does not. The upper (or lower in the photo) white delrin portion houses the three bearings, and provides a good amount of tip weight.
It still has a nice upper portion to the tip which makes it easy to grab and slap-spin it like a basket ball. I've never got it spinning fast enough that way to let go of the tip and have it spinning in my hand on it's own, but it should work to drop it into a rollercoaster or drumbeat and get it going, the one-way bearing makes regens pretty easy.
A note to whoever wins Nimbus; the one way bearing slips a little. It is still very efficient for regenerations. Actually it means the axle can't lock up. By that I mean if the axle is totally tight, because of the torque on this large of a top, the one way bearing can actually cut the axle and the whole thing has to be taken apart and sanded down. Probably wouldn't happen from standard play, but... Anyway, never fear, this top comes with a mechanic... me
About the name, my buddy Dustin has been practicing his airbrushing, he's painting flames on mailboxes for friends. He's working his way up to paint his step-side truck. He did this one mailbox that I saw on Facebook:
and I just had to have him do something similar on my top. The paint has lots of depth, it kinda changes colors and the flames kinda melt away as you walk around it. I like the flame shape but cloud colors thing, so thinking about clouds, nimbus is a name for a type of cloud and when I looked up the definition, I was sold on the name:
nim·bus
noun?/?nimb?s/?
nimbi, plural;?nimbuses, plural
A luminous cloud or a halo surrounding a supernatural being or a saint
A light, aura, color, etc., that surrounds someone or something
A large gray rain cloud
