Ok, this might seem like a bit of a dumb question, but I am thinking of lathing my own wooden chop bowl. I don't have the tools to make something with an aspect ratio of a cup. Anyway, gluing up the blank gives me the perfect opportunity to chop the bowl; however, is it better to use a steel disc or a rare earth magnet disc? The other complication is that if a chop ball has a magnet and the chop bowl has a magnet, several bad things could happen: 1)They stick too well, 2)the ball gets repelled (although it should just flip to the other pole). If I was using some nonspherical, hard device in the bowl it would probably make a clicking noise as it flipped. I guess I am answering my own question, but I am afraid that using a piece of steel won't be good enough to let a magnetic ball stick. Any advice would be nice!
Definitely a nerd, in science, technology, and magic.

Simage,
Chop cups have a magnet in the base - the balls are steel shimmed.
You have to give it away to keep it.

The balls I got with my Don Allan Chop and Don Allan Pocket Chop have magnets, not steel shims. I know this because the balls attract each other.
I think the balls supplied with the Riser/Loomis mini-chop are steel shimmed, though. (I've not handled them, but vaguely remember a discussion in the forum about it).

Simage;
This is a project that you should be able to do. John, FYI - the balls in the Riser/Loomis Micro Chop Cups actually contain 3 very small and weak magnets. The tiny chop cup has one larger/stronger magnet. This balanced the attraction as we need it. Simage, as you have guessed the magnet/ ball problem is critical. You will need to experiment to determine what is best for you. Thickness of the wood and covering on the ball are both of concern. On some items that I manufacture the ball is steel (no magnet). On others the ball has the magnets and the cup steel insert. It is a balancing feat to get exactly the correct attraction. This fine tuning will take longer than the making of the chop bowl. You will need to decide if you want the ball to be magnetic or not - depending upon performing conditions and other requirements. It is always a compromise. Good luck. Jim |

Jim,
Thanks for setting me straight. I recently took my old Don Allan Pocket Chop (Rings N' Things, if I remember well) out of storage. Unfortunately, the original balls were missing and I have had a heck of a time findng balls of appropriate strength/size. It has been so frustrating, in fact, that I've decided to get the Riser/Loomis mini chop combo set. As I mentioned in a letter I mailed yesterday. Regards,

HI John. RNT apparently has "adjustable strength" balls.
Good luck Magic1 |

I have a nesting wooden chop cup set, (no idea who produced it) that has the balls stuffed with steel wool. They look like regular knit balls, but a little squishy.

I believe you probably have a mikame set made in the late 70 s |

Those are the Mikame sets, there were 2 models made, the single cup and the double set. One uses the traditional gaff, the other used a rather neat concept,
but for whatever reason was not used in the future.
