advantage is chat it allows you to keep a moderately strong, sharp edgc while lowering your anglc of attack. This mcans that your chrust is not wasted downwards. NotÄ™ that in FigurÄ™ 1.35 the chisel edge of approximately 15° would be suitable only for soft timber. The inside bevel makes a combined angle of 25°. For hard usethe bevels may be steepened. Ali angles arc approximate. The inside bcvcl also means rhat an invcrtcd tool can be used instead of a backbent to create a long, convex chamfcr (Fig 1.36).

CORRECTING THE SHAPE

If the edge is not straighr or is damaged it should be squared on the end of the coarse stone (Fig 1.37). If you thcn look on to the edge you will see a white linÄ™ probably varving in thickness (Fig 1.38).

Putting in an Inside Bevel If you intend putting in an inside bevel you will need to see bright metal right across. This bevel is ground in next. Puc oil or water as appropriate on the slip or the tool to floac off the wastc metal. Rest the coarse slip stone in the flute with the end overhanging. Tilt che slip at a shallow angle (probably lower than 10*). Slide the slip back and forth, working from one corner of the gouge to the other, frequently chccking that the back linÄ™ of the bevel is paraÅ‚ lei with the front edge, l-2mm (¹/32-^,/ióin) deep. It is easier co maintain
