A woodworking apparatus comprising:

• a pair of elongated parallel members;
• multiple spacers for securing said pair of elongated parallel members to each other;
• a pair of slidably mounted bodies mounted on said pair of elongated parallel members;
• means on said pair of elongated parallel members for measuring the distance between said pair of slidably mounted bodies, and including a plurality of holes positioned at graduated intervals along said pair of elongated parallel members;
• said pair of slidably mounted bodies further comprising a first and second frame member having multiple clamping bodies mounted thereon;
• said multiple clamping bodies being slidably mounted on said first and second frame member;
• a pair of slotted tracks on opposing faces of said elongated members within which said pair of bodies slidably operate;
• said pair of bodies further including a first body being slidably and selectively positionable along said graduated intervals of said elongated parallel members, and a second body being threadably adjustable along said elongated parallel members;
• and
