Abstract:
A method of retaining parallels against the jaws of a vise, each parallel including opposite end edges, comprising:providing a plurality of spacers having different configurations and spacing widths corresponding to the widths of the workpieces to-be-clamped in the vise, said spacers including pressure exerting areas and being manually resiliently compressible to decrease the spacing width between their pressure exerting areas for enabling insertion of the spacer between the jaws of a vise,selecting one of the spacers or a combination thereof corresponding to the width of the workpiece to-be-clamped in the vise,inserting the selected spacer or combination of spacers between the parallels in the vise and onto the ways thereof with certain of the pressure exerting areas of the selected spacer or combination of spacers bearing against the end edges of at least one of the parallels,inserting a workpiece between the jaws and onto the parallels, andclamping the workpeice between the jaws while simultaneously compressing the spacer or combination of spacers to increase the compression thereof and allow pressure to be applied thereby against the parallels to maintain them against their jaws.
