    Wood turning

    Wood turning

    Wood turning consists in cutting the processed material with a turning knife or a hand-held chisel (wood turning); the cutting tool then being almost stationary, however, the turned material rotates.

    The piece of wood to be turned must first be prepared for processing. This preparation consists in determining the axis of the future bored workpiece, and hence, the exact seating points of the three-prong driver and the tailstock cone, and initially giving the material an approximately circular shape.

    We fasten the prepared material on the lathe, taking care, so that the driving trident is pressed into the front surface of the wood no shallower than at 5-6 mm. The same goes for the tailstock cone, under which a drilling with a twist drill should be made with a diameter of approx 4 mm, in depth 8 mm. However, because the cone of the tailstock squeezed into the wood resists (which is the result of the cone rubbing against the wood), so it is worth squeezing a little bright one into the drilled hole, thick grease, for example STS grease or the like, or even a few drops of machine oil. The hole for the tailstock cone must be lubricated very carefully, so that the grease does not stain the turned wood and thus destroy all the effort put into the processing of the element.

    Another important issue is the correct mounting of the so-called. a support that supports the chisel. Let's try, that the edge of the support is as close as possible to the processed surface. The height of the support must be this, that its upper edge is exactly at the level of the wood axis.

    And one more important relationship: the cutting angle of the wood has to be the greater, the harder the wood we are going to roll. So in the case of linden, the angle will be small, while for oak wood it is large, that is, close to 90 °.

    Turning is not difficult, on condition that they are fit, sharp turning chisels, good turning material and, of course, some practice. When starting to roll, it is necessary to wear protective goggles, because the splinters of wood generated during work can be very dangerous to the eyes.
