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: Specs: 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.
