Mrcnja's Mods

I know I wanna see who has a better price.

I am not going to play the price game just to undermine my fellow modders. With that said, for my lighter work I generally charge a price that is not far removed from those who come and go, but work for next to nothing. I have also done plenty of mod work for contributing community members at the rate of pay what you want. I don’t do this for the money.

Let’s take a look at the YoYoJam Classic for a moment. In past discussions about modding them people have wondered about what they look like without their caps. Allow me to shed some light on the subject. Under the caps, the body of the yo-yo looks like this:

They use the now standard YYJ solid spin axle, but the hub is pretty beefed up. I bet these yo-yos would take a considerable beating before the hubs took any damage.

This is the profile of the inside of the caps:

The caps are simply press fit into the body without any glue. You can remove them without much damage if you are careful and use a thin enough blade to pry them from the body. However, without a good way to hold them, it could be a dangerous venture. I used one of my lathe arbors to hold the yo-yo half and keep my hands out of harm’s way. Putting them back in place would be done by freezing the cap and warming the body, pressing the parts back together, and allowing them to come back to the same temperature and tighten up.

It feels like roughly one third of the Classic’s weight is in its caps. (Someday I’ll actually own a scale accurate enough for yo-yos.) Those looking to cut into the center of the caps to mod them into lateral caps should know that the center of the caps are about 3mm thick.

You can all thank iYoyo58 for letting me work on his Classic that you see here. More work on this yo-yo is coming soon.

Would it be possible to take the caps of a Surge sand down the rims and put O Rings in and keep it in the 66-68 gram range?

I would just shave down the caps.

Thanks for the pics man! You still have the cap design I sent ya right?

How do you high wall a yoyo?

With a lathe…

This yo-yo has been one of my most stressful mods that I have ever done. With that said, it did turn out very nicely.

My first real roadblock was that I could not get this yo-yo to take dye. I spent a full day trying everything I could, but still could not get any results. As it turns out, in 2011 Rit created a new dye formula and started phasing it in on some colors. I suspect that by now they have moved their entire product line over to the new formula. The new stuff is supposedly way better for dyeing natural fabrics like cotton, but it is horrible for plastics, especially delrin. With some late night research I discovered this fact and also read that iDye Poly works great. Armed with this knowledge, I bought the right dye and had success the next day.

The next problem was that I had no idea how I was going to hold the delrin and make these caps and I only had enough delrin for one attempt, so I had to get it right. A little in the moment ingenuity saved the day and I was able to make these custom delrin lateral caps.

Maybe

High walling is a pretty simple facing operation on the lathe. You just shave off however much of the face of the yo-yo you want, but it is best to leave the lip between the response and bearing seat alone so you don’t have to adjust the bearing seat.

What exactly is the yoyo ad what work did you do on it? I can tell is dye.

Looks like a YYJ Classic with black dye and custom delrin lateral caps.

My yoyo looks amazing. Can’t wait to get it!

That is just pure awesome.

Maghee sent me four wooden fixed axle yo-yos that were in need of repair. One Apollo had the axle snapped completely in half while the others were worn and had lost most of their strength.

To repair these yo-yos I first cut their existing axles in half and machined them down to be flush with the body. Then the body was drilled out and threaded inserts were fitted. The result is a take apart wooden yo-yo with a replaceable TMBR axle.

To continue exploring the measurements and design of various yo-yos and parts: TMBR axles measure about 1/4" in diameter, have a 0.525" length, and are drilled with a 9/64" bit for a 6x32 axle.

MetalMilitia sent me a collection of Freehands to silicone recess.



I also removed the sticker lips and polished the yo-yos.

Hello, I saw your thread on yo-yo expert forum. I am looking for someone who can build me a throw. I want a replay pro, size and shape, with a deep finger spin cup just like the arrow elite. Is that something that can be done?
