Ego Spinner – Update 5
Boy, have I got something to show you today!
Actually – two things.
The very FIRST production Ego spinner has been made. Yes, only one. This one:
A couple of important things…
This is straight off the cnc machine and raw. This means I have not done any of the finishing/tumbling processes on it (I wanted to get this photo to you before I run through the surface finishing process on it). So, yes, it is covered in sharp corners …sharp edges …there are “ripples” …there are machining lines.
The other thing is that I need to do some testing of this final production version to make sure it works the way I designed it to. So a little bit of testing to be done (and possibly some tweaking …but, truthfully, it’s performing pretty well so far).
Right, another photo:
As you probably recall from the pre-order page …The Ego is a fairly thick spinner. And, as a result, this gave me a little room to “play” with.
And with that extra room I’ve upgraded the Ego to have dual-bearings. Yep, you got it, your Ego spinner houses TWO bearings.
Why is that a good thing?
Well, if you’re familiar with spinners, then you already know. But this is for those who have not owned a spinner before (I know there are quite a number of people who held off buying anyone else’s spinner until I produced one …which really makes my “Ego” go through the roof :-P).
When a spinner is spinning and you change axis (i.e. go from holding it horizontal to holding it vertically) there is a vibration that occurs. This is always down to the bearing. It’s the shifting of the balls inside the bearing as you change axis. Some bearings are worse than others.
The dual-bearing eliminates this. Now, honestly, I understand the physics of it …but I just don’t know how to explain it. Can anyone in the comments help me out in describing why the “judder” disappears when you have dual-bearings?
Oh, and there is one more thing…
I’ve UPGRADED the bearing retention mechanism.
Initially the mechanism was going to be a “c-clip” type thing …and then I wanted to make it easier for you to insert and remove bearings – which led me down a path using some sort of screw-in/clip-in holder.
But, in trying to maintain my “impossibly high standards” (as well as aiming to simplify as much as possible wherever I can), I wondered if it was possible to just have the bearings “click” in. So my machinist and I set to work. And…
Did it work?
After a lot of testing and tweaking my machinist and I managed to get it done. Not only that …but I’ve been testing it do death with various bearings and it’s working damn well (with the caveat that ceramic bearings a little tighter to go in and out than steel bearings).
Here are a couple of the “blanks” we used to test the bearing retention as we developed it:
So, yeah, I think that’s it for today. I hope you enjoyed this update.
Any questions or comments?
