Product Guide: Ever Increasing Circles

The problems with cutting circles and ovals are that you want the cutting blade to move around, in some cases, quite tight curves and, at the same time, cut cleanly at an angle of 45º. The solution is to use the tip of a scalpel blade so that the width of the blade does not prevent “cornering”. Then by making the blade repeat the cut, each time at a deeper setting, the tip will eventually complete a cut through the thickness of the selected board. A final issue is to ensure that the axis around which the blade turns remains in the same place. Quite an engineering conundrum. However, what you end up with is a machine such as the Logan oval and circle cutter. This hand held tool is actually quite a fine piece of engineering and because of the restrictions on how it has to behave, is not something to be handled roughly.
