Most comfortable furniture, “serious” joinery collect connecting parts on the thorns. Technical requirements for the quality of such nodes is usually very high. Run them by milling or using special equipment. Existing designs handmade kiparisov, regardless of their complexity, there are drawbacks, and one of them — a large thick spikes with little their length and the insufficient depth of the eyes, the inconvenience of zapilivanie, and hence risk of injury.
The proposed device, despite its simplicity, is unique and is devoid of the above disadvantages. It consists of a rigid metal strip with two handles and a set of plates-spacer plates between which are clamped two of blade. Assembled this package with both sides (at the handles) is tightened with screws M5. Together with a steel band saw blades give the whole structure rigidity, so necessary for quality performance. Steel strip is selected with a thickness of 6 mm, and a blade — carpentry hand saws. Use a cloth bow forks is impossible, as it is thin, will bend, and hence will not provide the desired quality. Plate spacers can be made of any solid material: Plexiglas, textolite, plastic. Among them is the need and such, the thickness of which is equal to size of divorce drinking. This condition is required to ensure an exact match of the obtained sizes of thorns and eyes.
