The knives are now ready to be ground.

FREE HAND METHOD OF GRINDING TENON CUTTERS TO GAUGE.The template supplied with the machine is used when free hand grinding tenon cutters to gauge.It is necessary to ensure that the cutting edge of the cutter is shaped correct to the templateotherwise the tenons will not be flat or parallel.The correct cutter angle of 30 0 should be maintained. This is to give the correct strength tothe cutting edge and clearance on the cutting track.Hollow grinding is recommended wherever possible, as a perfect cutting edge is more easilyobtained by stoning. When stoning a flat ground cutter a good edge is more difficult to obtaindue to the tendency to rock the stone and leave a convex face. When hollow grinding is carriedout the angle of the cutting edge should be kept as near 30 0 as possible.SETTING UP STAND T. S. S. FOR TENONING HEADS. FIG. 31.Setting up the curved adze cutters on horizontal tenoningheads can be considerably simplified and speededup by the use of this stand.On the stand are engraved a series of curves representingthe cutting track of cutters used on various machines.The wood block is first adjusted so that it is inline with the appropriate curve.Fit the head on the arbor up against the locking collaras shown in Fig. 31. Rotate the cutterblock to checkthat as the edge of the cutter passes the centre of thewood it just touches -all along. The cutter will needadjustment either if it will not pass the wood or if thereis a gap between the cutter and the wood.The head is slightly tapered to obtain undercutting ofthe shoulder as described below.CUT OF THE HEADS.The cut of the heads is shown in Fig. 32. The undercuttingof the shoulder, which is exaggerated, is necessaryto ensure clean fitting shoulders when crampedtogether.Fig. 32Page 27PO CKET.www.wadkin.cominfo@wadkin.comSHOUL.DE.R. .
