Happy New Year all.
I fancy having a go at gypsy setting some small cabochons in nuggets made from some of my scrap silver (although I'll probably start with some copper first). I've bought a few ball burrs and today came home from work to find my Universal handle has arrived http://www.cooksongold.com/Jewellery...prcode-999-AZM. However, on having a quick play (not with any metal yet, I need to save that for the weekend, just tried it out on my chopping board in the kitchen) I've discovered that although I can tighten the chuck to seemingly securely hold a standard sized burr, if I apply any downwards pressure then the burr shank slips down inside the neck of the handle. I've tightened it as much as I'm able, and checked that the 3mm collet supplied does indeed reduce down to 2.3mm once tightened with the chuck.
I'd be grateful for advice on how I get this seemingly simple tool to work please. What on earth am I doing wrong?
