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.
