Since the days when “Tsar Peter arapa married”, carpentry work associated with a large number of planing boards or timber, produced a two-handed plane. Such a tool would no doubt be useful for beginners and vacationers, the area which has no electricity. It is also important that the width of the cutting edge can reach up to 90 mm, whereby the productivity of labour thanks to the efforts of two people is much higher. In addition, it does not require any workbench: can be planed, sitting right on the stack of processed boards, the length of which is not limited, since most work is conducted outdoors. Movement partners resemble a rowing boat: one pulls a plane behind the front handle, and second — is pushing at the rear.
Depending on your technical and financial possibilities of such a plane (let’s call it “PushPull”) can be made as all metal, and solid wood. For all-metal construction should be selected and cut thin-walled steel channel flange width up to 100 mm (preferably from a welded aluminum alloy) and the cut area size 75x50x5 mm length 100 mm Length of channel should be 270 mm, flange thickness of profile is desirable to be increased to 5 mm (at least in the mounting area of the cutting knife) by milling. At a distance of 80 mm from the leading edge in the wall of the channel making the cut from shelf to shelf with a width of 8 mm. Reference plane for the blade is formed by welding the slot (carefully pre-fit in place) of the polygon so that the angle of inclination of the glands of the plane was 40 degrees.
Fixation of the cutting knife is effected by means of a clamping wedge, in which is screwed the M8 screws supplied, with the large head with the notch. Support for locking of the wedge is a stud, screwed one end into the threaded hole M8 flange of steel channel and fitted with a slip fit into the hole on the opposite shelf channel.

R and S. 1. Solid metal construction with a two-handed planer:
1 — “block” of the channel, 2 sleeves, for pens, 3 — foot area, 4 — piece (knife), 5 — a clamping wedge, 6 — screw, 7 — resistant hairpin.

R and p. 2. All-wood construction plane
R and S. 2. All-wood construction plane:
1 back pad, 2 — pads cheek, 3,9,— back and front handles, 4 — piece (knife), 5 — screw, 6 — clamping wedge, 7 — thrust pin, 8 — front pads, 10 — sole.

The planer knife is made of carbon tool steel, allowing the heat treatment (U8A, 45 Steel, etc.) with a thickness of 4 mm; a sharpening angle of 35 degrees. You can use the knives from the planer, available for sale.
“PushPull” you can run and solid wood. Pre-manufactured front and rear parts of the plane, then merged into one by attaching the side cheeks made of plywood thickness of 5…6 mm.
The sole of a plane, it is desirable to make removable from Micarta, textolite, or PTFE with a thickness of 5 mm, attaching it with glue and screws with conical (secret) head. In the manufacture of wooden plane, mapping out the size of the pad width should be based on the width of the glands for him.
The level of performance of joiner’s works is largely determined not only by the skills of the joiner, but the quality of the applied tool, including acute sharpening of cutting edges: the plane of the knife blade of plane or chisel must be flawless. The skill of training tool does not come immediately. So lover is better to make a special fixture to facilitate this difficult operation. The efforts expended on its production, met EA account quick sharpening and the best sharpness of the cutting tool.
A device for sharpening a cutting tool
A device for sharpening a cutting tool:
I — base, 2 — bar, 3 — piece (knife), 4 — block, 5 — clamping wedge, 6 — cheek clamping node 7 and thrust pin, 8 – screw, 9 —niche of the bearing 10, the axis of the bearing 11 — bearing.

The device consists of pads in the form of a triangular prism, the end surfaces of which screws are attached two steel cheeks with a thickness of 2-2,5 mm. And in the corner of the bottom plane is a roller — bearing of small size. In steel cheeks threaded set pin with a diameter of 5-6 mm, which is a stop for the wedge-clamping, which can take from a plane or manufactured specifically for this purpose.
Note that the dimensions of the prism cannot be arbitrary: delinv its base should correspond to the length of the abrasive block, which will be sharpening and the angle of the knife is equal to or slightly more than the required angle (approximately 35 degrees).
The prism is easier to fabricate by gluing kit of plywood parts. In the Central parts of the case provides a cutout for the bearing and related parts of the set are drilled the holes for the bearing axis. Assembly begins with gluing to the Central parts of the side elements, in which holes is inserted the ends of the bearing axis. Then to this unit glued the other side panel. The plane of the fixture finally is processed after the complete curing of the adhesive.
To install the abrasive stone when sharpening with this device it is desirable from the Board to make a base.
