OT: mini id collets?

Anybody know of a collet supplier with id collets in the 1" long x 1/2 to 5/8 diameter range? i will need to grind a locationg dimater in the end and
it will need to slide over another expanding collet to be actuated by. go to http://www.roviproducts.com/expandin.htm#mini to see what i mean. basically i am using a mite-e-bite id collet to drive the machinable mini collet. the smallest rovi offers is 1 5/8 long x 5/8 diameter. much too large for my app. if i can find a smaller version of the machinable mini collet i won't have to have them made from scratch. any help will be GREATLY appreciated. TIA!

Just a thought but look for 'Unimat' or 'Taig' collets or 'mini mill' or 'mini lathe' in google or ebay. These are collets for lathes and mills mainly known as Jewelers lathes and mills.
