The turning of wood, which allows to make pieces with complicated shapes, does not involve the use of complex machines. There are full-machine wood lathes, but also good drills adapting machines: the resulting machine differs little from a fixed station. Turning the wood requires a solid experience difficult to acquire. Start by turning simple pieces and train regularly.

Setting up the room of the room to turn
1. The tower includes a base, or frame, which carries at one end the drive system (drill reversed and fixed). This set is mobile on a rack rail. On the other side of the frame is the support of the clamping point of the part to be turned. The principle of operation is simple: the piece of wood, clamped between the two points (or tower dolls), is attacked with tools as soon as it turns. During work, an adjustable guide, also mobile on the frame, supports the tools. The tour is presented here with the three main tools used: the chisel, the plane and the gouge. The lapidary tray (or pigtail) is used to make hollow objects (bowls).
2. Adjust the drive tip on the drill. This tip is called "claw" because it consists of a central tip and two lateral claws. This claw penetrates the piece of wood, ensuring a solid grip. Check during shooting this grip on the wood: it weakens when the piece turns a long time.
3. Attach the drill to the bracket. Tightening a single screw at the back of the drill ensures its stability. The support of the feed dog is fixed once and for all on the frame according to the length of the part to be turned. Perform all these drill operations unplugged.
4. To properly position the piece of wood to work, locate the center of its end face by drawing the diagonals. On a circular piece, determine the center with a compass. To reduce roughing work, cut the edges of the workpiece with a circular saw or planer after drawing an octagonal line to guide you.
5. Place the prepared piece between the dolls of the lathe; blow a mallet to make it penetrate the training shoe. Tighten the stub end until it also penetrates the wood. Screw it into position, after placing a drop of oil on it to facilitate rotation. A strong cardboard template gives the profile of the piece to be made, here a candlestick.
Machining the part on the lathe
1. Start roughing with the gouge after starting the machine. Remove few woods each time; continue to obtain a cylinder with a diameter slightly greater than the largest diameter of the finished part. Hold the tools with both hands and place them on the fence, located very close to the room, a little above the axis.
2. Place the template on the cylinder and mark in pencil, while the tower continues to walk, the different markers. Present often the template in progress: it remains your only reference in this work. Be careful not to cut the coin too much each time.
3. Continue to trim the thinner parts of the candlestick with the gouge. The chisel also serves to dig the different reliefs of the room. The chisel is generally used the bevel above; it allows to round the angles. For the finishing of the cylindrical parts (after roughing with the gouge), use the plane, tool a little difficult to handle. We must attack the wood of the cutting edge; An angle attack may explode the wood. The gouge is used to make the throats: attack the wood by the side of the gouge.
4. Using the template, check the turning correction. It's hard to get a perfect piece right the first time. Practice first to make cylindrical parts to acquire the hand, the regular movement of the tool that can remove the right amount of wood. This candlestick, rather simple piece (compared to the table legs), yet requires a good experience. If your drill has multiple speeds, set it to the slowest for roughing, and the faster for finishing.
Sanding and finishing
1. Sanding: Start with medium-grit sandpaper and finish with a very fine grain. To sand the bottom of the grooves, fold the sheet of sandpaper or wrap it on a thin block of wood. Sanding brings out the wood of the wood; the wire must always be in the width of the object. To give a beautiful polish to the candlestick, use at the end of sanding sandpaper very fine grain, and very used.
2. Remove the piece of wood from the lathe and saw cut off the logs at the top and bottom of the candlestick. Sand the bottom of the object and check the plumb. Pierce the top with the drill to introduce the candle. Pass a coat of varnish in finish.
3. To turn a hollow object, attach a piece of wood to the pigtail, which consists of a metal disk and a threaded rod. Screw the piece onto the pigtail and place it on the drill. Install the tool guide as close to the workpiece as possible, slightly below the axis of rotation. Work to attack the side that is turning up and down, that is, to the left (the coin is rotating counterclockwise). The roughing is done with the gouge and the finish with the chisel. A template ensures greater accuracy of work. Finish with a sanding and a coat of varnish.
