To create a lathe-boring woodworking machine me prompted memories of school days when in the classroom I received the first skills of work on a lathe — lesson interesting and exciting. Since then, as they say, much water has flowed, but the desire to do of wood pieces of furniture with a beautiful chiseled details is preserved, but the necessary lathe I had. And I decided to do it, adapting to the bed of the other machine, consisting of a “circular saw” and electrofunk (see “M-K” № 1 ‘2011), thus obtaining woodworking mini-complex.
The process of designing and manufacturing lathe were occupied not less interesting than megachilinae details on it, because it wanted to build multipurpose transformable machine, which could perform several operations. I think that I in some way failed because the machine can carry out turning, drilling, slotting and grinding operations. Various additional devices significantly extends the functionality of the machine.
Important advantage of the machine is that it is relatively simple in design, as its main components: front and rear headstock, the drilling head is constructed on the basis of the same body of the worm gears, and therefore relatively difficult to manufacture (although some parts had to be ordered turners professional), reliable and easy to use.
Multifunction wood cutting machine:
1—the guide of the frame (channel No. 12. 2); 2—cross member of the frame (channel No. 12. 3). 3 — tailstock with quill; 4 — front headstock; 5—handrest: 6—driven pulley belt transmission: 7 — V-belt; 8 — drive pulley V-belt transmission; 9—the electric motor (3-phase, N=0.7 kW, 2850 rpm); 10—a bracket of fastening of the engine to the frame (steel sheet s, 2); 11 —control; 12—disc saw; 13—rotor plane; 14—driven pulley belt transmission “circular saw”: 15 — V-belt “circular saw”: a 16—drive pulley V-belt transmission “conveyers”; 17—motor “buzz-saws”; 18—frame “conveyers”; 19—Playground of the motor 20 is a table of the circular saw; a 21 —table planer
Structurally, the machine consists of frame, electric drive with V-belt drive, front and rear attendants, boring side of the head. The attentive reader will notice that this is not mentioned in the frame (or base) of the machine, and the basis for lathe serve as a frame table and other woodworking machines — circular saws, combined with the plane. This constructive solution, maybe someone will cause disapproval and even censure, but I think that it is very rational: saves space, materials. Frame is installed on pre-laid on the table of the planer with wood blocks and attached thereto by clamps.

The frame is made of a pair of segments (with a length of 1400 mm) of the rolling channel number 12 (wall height is 120 mm, flange width — 52 mm) — guides connected (welded) in three places (on the edges and in the middle) short segments of the same channel. In the upper shelves of almost the entire length (excluding the left edge) is made through the longitudinal guide grooves, which move the tailstock, armrest or backrest. In the left edge along the axis of the grooves drilled holes for permanent mounting headstock. About the middle of the length of the frame in the grooves left by the jumper, through which these fixtures are rearranged. This creates some inconvenience (though this happens infrequently), but retains the stiffness of the guides. The grooves are cut with a angle grinder, pre-drilled at their ends in the ground jumper the appropriate holes with a drill. The final finishing of the grooves performed by grinding the edges of the rails, controlling the quality of work ease of movement of the tailstock.
