If a plane does not work properly the fault often may be with the back iron. If the back iron does not fit perfectly close across the full width of the plane, the shavings get between it and the cutting iron and clog the mouth of the plane. The remedy is to fit the edge of the back iron to the face of the cutting iron. This may be done either with a file or by bending it over a piece of round iron with a hammer. A defect often found in back irons is that of slipping over the edge of the cutting iron when the screw is tightened to hold the two together, thus destroying the edge. This sometimes may be remedied by roughing the top end of the back iron where it fits on the top of the cutting iron, by placing it on a flat file and then hammering it; or the screw may be tightened with the back iron some distance back from the edge, and afterwards gently hammered to its proper position.
