Using an English wheel is quite labour-intensive, but can be customised to produce a number of different panels using the one machine; simply switch out the anvil wheel to suit.
To use an English wheel, the operator passes the sheet metal between the anvil wheel and the rolling wheel, which causes the metal to stretch and become thinner. As it stretches, it starts to curve over the anvil wheel. This process is repeated until the operator achieves the right curvature or 'crown' from the material.
Most English wheels are based off one main design; where the sheet metal is fed through two rolling wheels manually to stretch it and give the metal a curve, as described above. If mass production of panels is required, then you may be better off with a stamping press instead.
The design of the frame is one of the most important things to note, as tubular frames are most effective on thinner or softer materials, while steel frames can handle thicker materials. An English wheel that is properly equipped will have a range of anvil wheels to match the required curvature.
One of the main things you will want to keep an eye out for when considering English wheels is the throat; the larger the throat, the thicker the material that can be processed by the machine. There are some limitations when using this machine, such as: the thickness of the sheet the machine can handle; the size of the workpiece and whether the operator can physically handle it; the larger the panel, the more work is involved.
The English wheel is a tool that has been around for many years, and used in many workshops across Australia. Be sure to note the steel capacity, throat depth, and whether the unit comes with a range of anvills or whether those are sold separately.
As always, confirm any queries with the dealer or seller of the English wheel you're looking to purchase.
