This is somethin i had in mind lately. So i asked around in my circle of friends who wants to have sum and one of the juggler-girls said, yes, she'd love to have sum for upcoming shows.
I use technics from www.mailleartisans.org to design my stuff. So (almost) all parts/units, including tutorials on howto make them, can be found there.
As material i basicalley used aluminium scales, aluminium rings and brass rings:
Scales: 35mm length, 22mm width,1,3mm thickness
RIngs: 1,6mm gauge, Inner diameter: 11,52mm; 8,8mm; 7,6mm; 6,4mm.
Source: I get the stuff from a german seller, but i suppose, he gets the scales from TRL (www.theringlord.com) and resells them; my scales are being connected with the 8,8-rings, but i guess, there'll be similar provided by TRL.
Step 1: Front
I made the cups by using a double-pyramid-system, say, i connected scales in rows from top to bottom: 1,2,3,4,5,6,7,6,5,4, then we removed the two inner-scales in the no.7-row.
I connected the cups with a "starfish-base unit" (11,52 center-ring; 6,4mm brass/alu) in the center: two ends are connected with the outer rings of the no.6-row, then we added two rings at each lower ends of the star with the rings of the lower no.5-row.
For the neckholder we decided to use flower-chains (6,4; 8,8), alternating brass and aluminium rings for the flowers. Reason for flower chain is that she said that best would be to keep the chains flat as possible, so that it doesn't hurt when she leans on sth with her body.
The lower scale-chain consists of a simple chain (i call it "klokette": toilet-chain), simply connecting brass rings with alternating a scale or an aluminium ring; rings used here are the 8,8-rings again. The ends are connected sumwhere in the outer region of the lowest scale/ring-row.
The last photo shows my second scale-bra made with mainly black materials; if there are any questions about it, just ask.
Step 2: Back
For the back we used flower-chain again, but inserted a triangle at the center based on the star-fish base again: starfish-base has 15 rings connected to the center ring, so its easy to connected either 5 or 3 rings to form the ends to make either a starfish with 5 points or 3 points (triangle).
For the scale-chain i used a left-over Aura-chain (rings: 11,52 aluminium, 7,6 brass), and replaced the lower rings by scales and connected the middle to the starfish-triangle and the ends to sum "flowers".
Then, for more comfort and becos the whole things' weight stresses the neckm we removed sum of the flower chain in the neck and replaced it by sum piece of gum string knotted to the flowerchain.
