This fixture was designed with the kind of engraving and stone setting done today. Often it is difficult to hold your rings in a position that is easy to work from when performing tasks such as stone setting or engraving on prongs. It seem that so many times I have found myself saying "If I could just hold it at this angle". Often times even when we can hold it at a particular angle there isn't clearance enough for my gravers and burs.
The solution was this fixture which is machined from 303 stainless. It comes with 4 collets made of solid brass with two expanding angles for a firm grip. The collets are split into three sections. This allows easy holding of rings especially when there not perfectly round. It take very little pressure to secure your workpiece.
The collets are designed to expand two sizes only. Therefore., these four collets will allow holding rings from sizes 4-6, 6-8, 8-10 and 10-12. The advantages are that you won't be looking all over for the right size collet. The brass's density helps to reduce vibration considerably, which means more of the energy from your tools will be directed to the work.
The system comes with extra o rings so that in the event that one is broken or they wear they can be easily replaced. Each collet is clearly marked as to the position of the section to each other form easy reassembly. watch the video
