Abstract
An adjustable miter bar assembly configured for temporarily securing a workpiece to a woodworking table miter slot, the adjustable miter bar assembly having a first elongated housing member with a longitudinal slot and a second elongated member slidably received within the slot. The interior surfaces of the housing and slider members are equipped with complementary angled tabs and angled adjustment slots, allowing for precise lateral adjustment of the dimensions of the assembly. This adjustment ensures a snug fit within a miter slot while maintaining longitudinal sliding capability. Embodiments may feature roller bearings on the exterior surfaces to provide smooth movement and reduce friction within the miter slot.
Claims20
An adjustable miter bar assembly comprising:
- a. a first elongated housing member having a distal end, a proximal end, an exterior surface, and an elongated slot extending along a first side of said exterior surface, wherein a first adjustable fastener is provided at said distal end that extends into said slot, and a second adjustable fastener is provided at said proximal end that extends into said slot, and wherein a plurality of angled slots are provided in the first housing member extending inward from the elongated slot;
- and
- b. a second elongated member operably adapted for slidable engagement with the elongated slot of said first housing member, the second elongated member having a distal end, a proximal end, an inside surface, and an opposite outside surface, wherein a plurality of angled tabs are located on said inside surface, said plurality of tabs corresponding to and operably adapted for slidable engagement with the plurality of angled slots of the first housing member;
- wherein the second elongated member is adjustably secured in said elongated slot by said first and second adjustable fasteners.
A method for securing a workpiece to a miter slot of a woodworking table comprising the steps of:
- a. positioning an adjustable miter bar assembly in said miter slot, the adjustable miter bar assembly comprising a first elongated housing member slidably engaged with a second elongated member,
- i. wherein the first housing member comprises a longitudinal slot along a first side thereof operable to receive said second elongated member, a first adjustable fastener provided at a distal end of the first housing member and extending into said longitudinal slot, a second adjustable fastener provided at a proximal end of the first housing member and extending into said longitudinal slot, and a plurality of angled adjustment slots in said longitudinal slot, and
- ii. wherein the second elongated member is slidably engaged with said longitudinal slot and comprises a plurality of angled tabs on an inside surface thereof, the angled tabs being complementary to and adjustably inserted into said plurality of angled adjustment slots, with the first and second adjustable fasteners being movably engaged with opposite ends of the second elongated member;
- b. engaging the miter bar assembly with the miter slot by cooperatively moving said adjustable fasteners, causing said plurality of angled tabs to travel along said plurality of adjustment slots, which causes said second elongated member to separate from said first housing member such that the miter bar assembly expands for tight engagement inside said miter slot;
- and
- c. attaching a workpiece to the miter bar assembly by engaging the workpiece with a plurality pointed shank members extending upwardly from said miter bar assembly.
An adjustable miter bar assembly comprising:
- a. a first elongated housing member having a distal end, a proximal end, an exterior surface, and an elongated slot extending along a first side of said exterior surface, wherein a plurality of first bearings are located on an opposite side of the first elongated housing member, wherein a first adjustable fastener is provided at said distal end that extends into said slot, and a second adjustable fastener is provided at said proximal end that extends into said slot, and wherein a plurality of angled slots are provided in the first housing member extending inward from the elongated slot;
- and
- b. a second elongated member operably adapted for slidable engagement with said elongated slot, the second elongated member having a distal end, a proximal end, an inside surface, and an opposite outside surface with a plurality of second bearings located along said outside surface, wherein a plurality of angled tabs are located on said inside surface, said plurality of tabs corresponding to and operably adapted for slidable engagement with the plurality of angled slots of the first housing member;
- wherein the second elongated member is adjustably secured in said elongated slot by said first and second adjustable fasteners.
