Milling a Dovetail in Plain Milling Machine Saddle on a No. 3 Vertical Spindle Milling Machine

The casting is held on a special fixture which has a slide corresponding to the slide on the top of the knee of the milling machine. The piece can be removed by simply loosening the gib.

The top plate of the fixture also swivels, so that one side of the ways can be milled on an angle for a taper gib. Both operations are, therefore, completed at one setting of the fixture, thus insuring the surfaces being milled in relation to each other. A 50° angular cutter is used for this operation.
