I didn’t pickup a Moistmaker, I’m simply not cool enough… however, I did snag a couple different Ti side effects from Onedrop.

I had issues with the kisses not sitting flush on a handful of onedrop yoyos. I quit testing because they were galling the side effect receiving area.

Onedrop told me this is how they were meant to be, and even sent me a replacement pair… that fit the same way and gall the same way.

Here’s my purple Parlay:

Same results on a Panorama and Bathysphere.
As you can see, though… the Ti Micro Caps sit flush, no problem! I do feel a little better that I’m not the only one having this issue. And I do say it is an issue, since no other pair of side effects has ever caused this kind of galling in any of my yoyos.

I’m sorry my Titanium Side Effects don’t suit you!
But for a little clarity, they look like they are fitting just exactly how they were designed to fit!
Here’s my drawing of the 2 Side Effects in question.
The Kiss, in yellow, sits about half a millimeter higher than the micro.
Just like it looks in your picture!

I’m actually stoked to see your picture, because it shows me that I hit my design correctly.
I don’t have all of these Onedrop throws to test them on!
As far as galling goes, maybe the picture just isn’t showing it to me.
Galling is adhesive wear, where one or both surfaces in contact with each other pic up material from the other surface.
I see evidence of contact, possibly even slight abrasion.
Again, by design.
I can be more precise, with Titanium, than one can hope to be with Aluminum, that then gets electrochemically anodized.
So that dark ring around the post of the Side Effect? Evidence of a very slight interference with the inside bore of the bearing!
Exactly what I wanted!
The evidence of contact in the YoYo itself? Meh, I wish there was a little more clearance in the throw on that straight diameter. (There could be, as it’s the tapered portion that is necessary for good function)
But that is a very difficult thing to completely control with extreme precision on an item that gets anodized.
Anodizing is equal parts art, and science.
While a good anodizer, like the company Onedrop uses will make everything appear the same, when you get down to measuring to the tenth of a thousandth of an inch, things are going to vary!
This part will grow microscopically more than that part.
That hole will go a tiny bit more out of round than this hole, etc…
All in the same batch.
It’s literally growing an oxide film on the aluminum surface, and dying it.
Science, and art…
All in all, that was a lot of words to say that based on the pictures alone, it looks like everything is fitting, and behaving, exactly as I intended them to!
And that may just not be everyones cup of tea.

Shimming may, or may not work on these.
They are designed different than a bearing, they are NotABearing…
By design, they don’t contact the ‘spud’ on the yoyo, but instead, fit in the pocket.
This is so you get a larger area of contact, and should help maintain parallelism better than a bearing can.
Still shimmable.
But likely requires different shims to do so.

If I cleared out the last of the not a bearings on accident feel free to cancel half my order. I don’t want to be greedy and take them all.

Or if there is some bizarre shipping accident and I only receive 2 and a ti se I wouldn’t be one to complain about it. :joy:

“I’m actually stoked to see your picture, because it shows me that I hit my design correctly.”
My misunderstanding then, it really seems to stick up way further than that though.

“I see evidence of contact, possibly even slight abrasion.
Again, by design.”
You intended to damage the ano in yoyos? That’s wild…
My understanding is that only the conical portion immediately above and below the o-ring are intended to make contact.

“So that dark ring around the post of the Side Effect? Evidence of a very slight interference with the inside bore of the bearing!”
It isn’t though, that portion is what’s making contact with the inner wall of the side effect receiver and damaging the yoyo. The bearing fits loosey-goosey on that post.

“While a good anodizer, like the company Onedrop uses will make everything appear the same, when you get down to measuring to the tenth of a thousandth of an inch, things are going to vary!
This part will grow microscopically more than that part.
That hole will go a tiny bit more out of round than this hole, etc…

Correct, ano isn’t flawless and doesn’t adhere to the same tolerances of fine machining. I am still going to argue that no other side effect has ever cause this kind of damage/marking/galling whatever you wanna call it on any of my yoyos, not even this Parlay. It was flawless before installing the Ti Kisses. Not to toot my own horn here, but I have one of almost every model of side effect that has been produced… and none have ever fit this poorly or caused damage to yoyo.

“I’m sorry my Titanium Side Effects don’t suit you!”
The Micro Caps are great! I’ve no issues with them. And I can’t speak to the Ti Spikes or Globes, since I didn’t manage to collect either of those. I really wanted to love the Ti Kisses, but this issue exists and they just don’t fit. I suppose it is what it is, I was just elated to hear I wasn’t the only one who considered this a problem and felt it was finally time to chime in.

if Brian is making more at some point then its not a problem that you grabbed the last of this batch.

To be fair, the Ti Micro caps from the first drop and the Kisses I got on the second drop work perfectly on all SE yoyos I have. I’m only seeing issues with the SE’s received in the “Bells and Whistles” Moistmaker. Specifically, the Orbs and one of the Kisses, but I need to do some more testing

My Micro Caps are from the first drop, and so were the first set of Kisses. I’d bet the second set came from that batch as well. If I recall correctly, onedrop sent me the replacements prior to the second drop.

I’ll try my OD Ti kisses with more throws when I get a chance. They worked flawlessly in my Deep State. The kisses are great for pull starts.

No intent to damage the yoyo, no.
Evidence of contact though? Absolutely not surprising.
Contact with the bearing there, is ideal, in my opinion.
I made them for Onedrop, to the specifications they gave me.
All I can do is give them the diameter that was asked for!
They did change that spec for the second run though…
If it was my IP, and it isn’t, I would likely have the hole in the YoYo about .001" larger than the diameter of the Side Effect.
Then the side effect could be toleranced differently, for a slight interference, to a couple of tenths clearance on the bearing itself.
The closer that fits, the more true the yoyo will run!
Concentricity between the bearing and YoYo body is of paramount importance in my mind.
That is controlled by the bearings fit to the Side Effect, and the tapers fit in the yoyo body.
If I made them smaller still, we would just be introducing more opportunity for error by a looser fit to the bearing…
You are saying the fit in the bearing is ‘loosey-goosey’ already…
I’d rather see a witness mark on the side effect from contact, than have a fit I’d call loosey goosey.
So, in my mind, I definitely don’t want to go smaller!

By no means think I am questioning how mine vs all the other Side Effects fit in comparison with each other!
I have next to no experience with comparing them.
I have a couple of throws here, and a couple of aluminum side effects, but not many, and certainly not enough to claim any empirical knowledge!
I’m a rookie here.
If you say it is so, I absolutely believe it.

I would expect titanium to behave / feel different than aluminum though.
And evidence of metal on metal contact is not unreasonable to me

I’ve only got a single Onedrop here, no idea what model it is. The other one or two must be at the house.
I just went and tested a random dozen of the Titanium Side Effects I have here in it, and they work flawlessly, in this one.
I can see a couple of rub marks in the ano on one side.
But that doesn’t surprise me considering I just pushed titanium through it a dozen or more times.
Nothing on any part here that I would consider damage.
Like the girl you bring home from a bar on Saturday night, there’s some evidence that something has been in there before.
But hey, something has…

That looks a lot like the Kamuraiju that I have coming in the mail.

I am not surprised to hear of titanium marking aluminum, it tends to be a bit… firmer.

If the machinist made the parts to companies tolerances, verified the tolerances on the completed parts, and then the company accepted those parts, I’d say job well done to the machinist. +/- .0002” is no joke

Overall I think most of your side effects are flawless, like the ones you tested here. They’re absolutely wonderful and the Kisses are my favorite in my collection, but I think a few may be just a bit off. I’ll demonstrate what I mean later with a video. I appreciate you being open and discussing this with us.

The second run of the Side Effects were actually +0 / -.0002"
Talk about no joke.
.0002" total tolerance.
I bought special Micrometers that measure to something like 5 MILLIONTHS of an inch, (0.1μm) just for these!
The micrometers cost almost the same as the invoice for the whole order!

Hey, I’d appreciate the demo.
And I am always open and happy to discuss.
It’s how I, and all of us really, will learn.

And I have a lot to learn in this realm…

Let me start with THANK YOU.
Awesome demo of the issue.
It’s great to have so many things on hand to be able to go back and forth with!

I suspect I know what is going on.
I’ll check when I get to the shop tomorrow.

Now, advice…
Next time something is stuck in one of those, stick an axle screw in it.
Push on the screw…
If you need to, push it against the table or something.
Don’t tear a nail!

And to see if the 1/4 diameter part is too big, you can see if it goes in from the other direction…
If it slides in easily that way, even more investigation will be required!

Again, thanks, great video.

You’re welcome! Happy to help.

Yeah, I normally push it against the table, so I was being a bit dramatic. ha!

I can confirm that it’s the same issue from the other direction.

Looking forward to what you find out!

I haven’t seen much about the Dessicator yet. How well do the weight rings secure? My wife is traumatized from some weight rings falling off another yo-yo during a forward throw lol.
