I would appreciate help from cup collectors who have a set of Bazar De Magia Combo cups. May I have the following measurement for the Bazar De Magia Combo cups?

* Height of 1 cup in millimetres -

* Height of 2 cups stacked together in millimetres -

* Height of 3 cups stacked together in millimetres -

* Inner diameter of mouth of cup (opening) in millimetres -

* Outer diameter of mouth of cup (opening) in millimetres -

* Outer diameter of bottom in millimetres -


Thanks in advance for the help.

James

Hi James, I use the Bazar De Magia Brass Combo set. Here's your info if I'm reading my mm scale right on my ruler:

Ht of 1 cup = 80mm.
Ht of 2 stacked = 125mm
Ht of 3 stacked = 165mm
Inner Diameter of mouth opening = 67mm
Outside diameter of mouth opening = 72mm
Outside diameter of bottom = 45mm

Hope this helps. S.R.

Just one correction: Height of 3 cups stacked together in millimetres- 175mm.

Hmmm, my ruler says 165 (?)

Sir Richard.

A BIG 'Thank You' to you, Sir Richard, for the measurements. It really helps.

Thanks to Walid Ahumada for the 175 mm height of the 3 cups stack info too. I will bear that in mind in the particular project I am doing now.

Another BIG 'Thank You' to both of you.

There is something wrong somewhere, 10 mm is a big difference, it can not be the cups, either Walid started from the 1 instead of the 0 or Sir Richard is measuring on a different scale. Strange cups, we need one more measurement ...

I used a yardstick that has the mm scale on one side & S.A.E. on the other. I had held the stack of cups in one hand, evened out the edge to match the top of the cups, & read the mm line that matched the bottom & got the "165" reading, I did this 3 times. Yet I just now stacked the cups on the table, placed the yardstick directly in front of the stack, & read the line that lined up with the top edge & now I'm coming up with 170 mm. I don't know why my measurements are different so I agree that a 3rd party should do another measurement for the sake of accuracy.

Sir Richard.

You are all assuming two things:

1) all of the Bazar di Magia cups are identical
2) all of the cups in a set of Bazar di Magia cups nest exactly the same way.

It may be that both of these assumptions are false.

There is a third assumption which is that the Bazar di Magia cups that were made at one particular time would be exactly like the ones made at another particular time.

This may also be a bad assumption.

As proof of my statement, let me give you the results of measuring a set of copper combo cups.

Two of the cups in the set were 82 mm tall. The other (gaffed cup) was 80 mm tall.

The nesting was such that if I nested the gaffed cup with an ungaffed cup, the two cups produced a total height of 129 mm. That's with the gaffed cup on the bottom of the stack. The other way around, the stack of two was 127 mm high.

My calipers will not measure more than 150 mm, so I can't help you with a three cup stack.

I was able to measure the three cup stack with a ruler. It came to 175 - 176 mm.

Thanks, Bill, for your input and measurement.

You are right. We tend to assume that the cups are always identical all the time. And we take that for granted.

I don't.

I did some checking & found that it depends on where the "chop-cup" is in the stack.
The "gimmick" takes up more room on the ceiling of the cup.

Sir Richard.

Of course, you don't, Pete. For those that are not cup makers or do not have a large collection of cups or vast knowledge of cup making, would assume a lot of things for cups. I am speaking for myself. LOL!

He meant like the royal We.

in my set it does not matter where the chop cup is in the stack, it is always 175 mm

Just like to understand further ... based on the above posts.
.

Does this mean there will be inconsistencies in different batches of cups made?

It seems so. S.R.

Correct me if I'm wrong but:

One problem with the bazar combo cups is that because the rib is so high on the cup (around the middle of the cup) you cannot put the chop ball on a normal cup and then place the chop cup on top of that, making the chop ball seem to penetrate the lower cup (used if one ball is already under the lower cup).

This is true with my set, but I guess its possible that the strength of my cup or ball may be too weak. Looking at the cup, I think its the design rather than the ball or cup.

Has anyone else had this problem?

This is exactly true. It's because of the kind of ball that they use. If you use a set of RnT II balls or a set of Mike Rogers balls with these cups, they should work correctly.
