Precision, quality and economics are the principal factors when goldsmiths make new investments in their workshops. Within this context, it need not necessarily be a major investment – small tools for manual applications can also prove their mettle with time.
Each new tool should support the goldsmith and model goldsmith in their work and should be noticeable in terms of efficiency. Stages of work that are simplified and facilitated save time that can be used elsewhere, even if one includes the time required to learn how to use and operate the new devices.
Bema systems for goldsmiths
If they weren’t already available, somebody would have to invent them: the Bema ring bending appliances. It takes as much skill as it does strength in order to bend solid, round, silver wire into rings. In order to employ the force correctly when bending an individual ring, the goldsmith requires sufficient quantities of round wire, a measure of which is superfluous to requirements after bending and must be sawn off. The ring bending appliance from Bema is not so frequently used whenever handling cast parts; instead it is used mostly when assembling jewelry parts that the goldsmith fashions himself. Examples of this include open rings with a setting, precisely measured material for individual rings or when bending a spiral. Whatever the case, goldsmiths save material and time. The wealth of accessories means that the ring bending machine can also twist spirals. Every goldsmith is familiar with horizontally winding a wire spiral using a clamping device. The ring bending device by Bema means that it is possible to roll a spiral vertically with the same techniques, even when dealing with longer material – for example round wire. The pressure roller has a spring mechanism, while the barrel is exchangeable. The ring bending device can also be adjusted in order to bend oval bracelets and rings, even using flat material. In these cases, interested parties should enquire about models. The standard, round, steel barrels have a diameter of between 15 and 32 millimeters. Two plastic barrels are available with 25 and 32 millimeters.
Stainless steel saw for emergencies
As early as the start of 2004, the goldsmiths Wiesner OHG presented the steel jewelry collection doubleyou24. Even when the collection was presented, Markus and Michael asked themselves which tools specialist retailers could use in order to work on overly tight rings, as traditional ring saws are not really suitable for stainless steel. Tool dealers were unable to offer a solution, so the Wiesner brothers decided to develop a ring saw specifically for stainless steel. The saw is now ready to be marketed and is sold by specialist retailers. Quite similar to a traditional saw in its optical appearance, the stainless steel ring saw developed by Wiesner is significantly better in its handling. Just like when wedding rings have become too tight, there is the risk that owners of stainless steel rings will have to have the ring sawn off laboriously in emergencies. The stainless steel saw by Wiesner has a “finger guard” in order to protect the hand; it is inserted beneath the ring. “We felt we had no choice but to develop this kind of saw and were astonished that no one could offer us a suitable tool, seeing as how stainless steel has been in trend for a few years now”, said the Wiesner brothers.
