What about a notch on the axle and the body, with a pin there? Like a half-circle on the outside of the axle and a matching one on the inside of the body, then a small dowel popped into it. Could be a slight pain to align the second half in assembly, but no worse than tuning a TMBR.
I really like this idea, but it would be extremely difficult to pull off as both notches would need to be created independently and very accurately.
I’m about 99% sure that all it will take it a tighter fitting axle.

They probably take too long to make to end up as a production model, still it works well.

Understandable.
But also disappointing; I love product designs that use magnets to keep things together, yet detachable.

Yeah, but in this case it might be more of a novelty.
Don’t get me wrong, it is super cool, and I’m sure it would perform well enough. I just can’t see it matching the performance of the regular glued together models. I could be proven wrong, of course.
All I know is I hardly play with any fixed axles other my Spinworthys, and mostly I’m just glad to get back to them when I do play with something else!
I do love the experimentation and ingenuity of it.

Why do you think that? The one I just made is performing very well.

I know it doesn’t matter as much for a fixed axle, but I thought that would be too much extra center weight. If i’m wrong, then that’s pretty awesome!

I do actually hate adding extra weight.

Right, my point wasn’t that it couldn’t be a good yoyo. My point was more that I love how your glued together models play so much, that I’d prefer to dig out strings, if a take apart came at a sacrifice.
I’d probably still buy one though…

I just can’t seem to get out of my mind that I need a take apart yoyo system. It’s a recurring thinking cycle I keep going back to.
I’m also so dissatisfied with every system out there. The only plus to every system I see is that they can be taken apart. Everything else is a downside. They are all not precise enough, not reliable enough or add too much weight. Mine fails the third, but I still can’t think of a way to solve that.
There is also the problem that any system doesn’t work properly with my dimple designs like the KNack. There is not enough room at the center to fit the hardware into it, or to accommodate an axle that is long enough. sigh 
All I really want is to give people the option to replace axles if they want to.

The magnet idea is super cool, regardless.
I love that you’re trying to find a better solution. Don’t give up!

I appreciate the perfectionist in you; as an engineer I can relate. But I’ve not heard @edhaponik, for instance, express much dissatisfaction with his TMBRs or his No-Jives, so I can’t help but think that maybe the “downsides” to today’s take-apart fixies aren’t really that big a deal.

Oh I think you’re right, the downsides aren’t a huge deal at all. I just want them perfect.
I have a TMBR yoyo, and it has flown apart on me regularly. I know with some tinkering this can be fixed, but I don’t want to make something that requires any tinkering at all.
As I’ve said before, I still think the TMBR system is very cool and pretty successful.

I’ll make a take-apart maple Harbinger today with a metal shaft with an axle sleeve.

The TMBR axle setup is kinda like fixed axle in general in that there’s a learning curve associated with tightening it so it doesn’t come apart. I have become very, VERY good at this lol. Can’t remember the last time it happened.
I agree w Glen though that no system is perfect and they all have liabilities. I love the idea of that magnet setup - super smart - but it’d drive me nuts if I felt it shift on a heavy Time Warp. The TMBR thing is a pain to make and people get justifiably bummed if it does come apart. I love the No Jive system honestly, but it’s a pain to cut those hexes clean. (Stupid No Jives - before them NOBODY cared if their yo-yo could come apart!)
It’s just tough to make a good wooden yo-yo, and tougher by far to make a lot of em. Respect to anyone/everyone chasing it!

Yep. It simply must not happen, or it’s no good.

I made this Skinflint today.
The first completely successful take-apart design I have made.
If anyone is interested I can explain in detail what I’ve done and how it differs from the other designs out there.

That is looking good.
