Hand turned yoyo: HTYY#0.44 (reply #186)

Really stunning work. Something about black and white delrin - makes them look so classy.

The 0.23 looks absolutely gorgeous. Is the vibe completely unfixable? I really really want one, and would be happy to buy one off you.

Also, the 0.26 looks great as well. Your work is just so pleasing aesthetically.

O.O these yoyos look amazing! I’m thinking once i buy a better video editing program i need one of these to my specifications!

Hi everyone.

I completed this little yoyo yesterday. Let me share with you the HTYY#0.29…

When I started making delrin yoyo about one and half year ago, most of them were 50mm in diameter. This was the right size for me back then. But I found it pretty hard to get a suitable weight around 65g with good distribution without the aid of aluminum rings (I don’t like to turn aluminum because it is a lot harder compares to turning delrin). Then I switched to 56mm as you can see in this thread. Until a few weeks ago, I came across pictures of CLYW Wooly Marmot and suddenly thought of making a delrin version of this yoyo for myself. I made a design based on the profile of WM and after a few days of hard work, here’s the outcome:

The delrin halves and aluminum rings

The HTYY#0.29. It is not quite the same with WM. The WM has a more rounded catch zone but mine is a bit angular :’(

How does it play? Well, the best I can describe is that it plays quite similarly to my One Drop Cafe Racer but softer due to its material. It has some vibe but it is within my acceptable limit. I like it a lot! It looks simple and nice to me. And it feels comfortable in my hand too. I am very happy with this little yoyo.

That’s all for now, til next time… thanks for reading.

Looks awesome!

I love those colors together.

Hi, I would like to share with you an update to this little HTYY of mine. After a few days playing with this yoyo, I found the hubs are a bit too long and looks bulky, a reshaping is needed. After about an hour of work, my HT#0.29 has gained a new look.

Here’s the “before and after” photo:

The changes are not merely cosmetic, its weight (center weight, to be more precise) has reduced by 0.6g. And this actually has some positive effects on the play characteristic of this yoyo. Firstly, I feel that it hits the bottom of the string more lightly upon throwing down. Secondly, it is less prone to tilt. All in all, I am very glad I took the effort to reshape its hubs and now, IMO, my HT#0.29 looks and plays better.

I just read through this thread today. Very cool, I enjoyed seeing how you progressed.

How do you keep both sides identical on a manual lathe? Do you have a jig set up for each design or something?

Looking great!

Hi, Eric. I am happy that you like my work.

And thanks for the question. I make all my yoyo with a metal minilathe which has indicators of the depth and length of each of my cuts, and I follow strictly to all dimensions in my design. You will know if you are familiar with metal lathe. But sadly, the halves may look identical, there are always some difference in weight between them, but I always try to make sure the difference is less than 0.1g.

Thanks, Greg.

Nice work, i like the progress and changes. someday i will get up the time and courage to try.

Thanks for the nice and kind comment, scooter. Your works are awesome, I think you should just do it :slight_smile:

I did some more refining on the profile of my HTYY#0.29. The weight has been reduced further to 60.85g. It feels light in hand but surprisingly it plays just fine and more stable, slightly better than before.

Nice work and good eye, especially since its all by hand.

Looks awesome!

Hi. This time I would like to share with you my HT looping yoyos.

Making a delrin looping yoyo has been in my to do list even before owning a lathe. Here’s my first attempt in making looping yoyo, about 3 months after playing with my minilathe. I must admit that I was inspired by the RecRev REBERB while designing the yoyo. I really like the idea of solid body with hollowed out inner wall, which can save me a a few machining steps. I did include an extra feature in the design where both side of the yoyo halves has a hub for the spacer with brake pads making them flippable. It allows me to study the influence of inner wall on looping yoyo.

Here’s the photo of my first delrin looping yoyo.

These are the sides with hollowed out inner wall.

This how it looks with them facing inwards.

This is how it looks when the sides with hollowed out inner wall facing outwards.

I am quite happy with my first attempt. I have to lube the bearing and wrap a few layers of string to make it responsive enough for me to do the loop the loop trick (I am not good with 2A tricks), but it did work. And I found that both walls make no significant difference in terms of functionality but when the hollowed out wall facing inward I can feel the string rubbing with the edge of the catch zone and hear a hollow sound during play.

And here’s my second attempt after a lapse of more than a year.

The experience that I gained from making string trick yoyos really helps in designing and making this yoyo. I have replaced the spacer system with a solid axle hub, and the brake pads with rubber o rings. I referred to the specifications of some famous looping yoyos and found that most of them have diameter, width and weight of around 57mm, 28mm (without cap) and 50g respectively, and I incorporated these spec in my design. I completed the yoyo last weekend.

Here’s the photos.

I lack the skill and experience to comment in terms of its play characteristic. I would say the HT#0.34 plays quite similarly to my YYJ Sunset Trajectory NXG (since both of them use rubber o rings). Maybe due to the material, I feel that my delrin looping yoyo is “soft” when holding in hand and slower during play while the Sunset Trajectory feels rigid and fast. However, there is one thing in the yoyo that I don’t like which is the weight. If feels heavy. And the weight comes from their caps. Each cap weighs around 5.5g. So just before I start writing this post, I have removed some materials from the center of the caps and reduced the total weight to 50g.

Here’s the final look.

I hope you enjoy reading this post and your comment is most welcomed. Thanks.

That looks great, looks even better with the reduced caps. Nice work!

That is pretty wicked to say the least.
Being shy of any spending money, I wish I had the tools or means to make my own custom throws like this. I love customization, and there just isn’t any feeling better than making or having something completely custom. Aside from money being an issue, that is why I make my own custom polyester strings.

Keep up the awesome work, maybe you be a top manufacturer one day!

I made myself a pair of looping yoyo based on the HTYY#0.34. I have discarded the cap and added a little bit of weight to the rim. Each of them weighs around 45.5g. I wish I have added more weight to the rim or at the center so that total weight would be around 50g. Never mind, to be continued…
