INTRODUCTION :
A vise is a mechanical apparatus used to secure and hold the object to allow work to be performed on it. The vises have two parallel jaws, one fixed and the other movable, threaded in and out by a screwor bolt andlever. Woodworking vise is attached to aworkbenchand typically flush with its work surface area. Its jaws are made of wood or metal, and the latter usually faced with wooden material, called cheeks, to avoid marring the workpiece. In the vise the movable jaw may include a retractable dog to hold workpiece against a bench dog. The quick-release vises employ a split nut that is allows the screw to engage or disengage with a half-turn of the handle of the vise.
When you need to exert bone-crushing pressure or securely hold very large projects, make your own clamps from long wooden block-clamp fixtures and small wooden blocks. Clamping capacity is limited only by the length of the long wooden block.
Parts Used :
- Long wooden block ( 39 “ length )( 2” width )
- 3 pcs Small wooden blocks (2”*2”)
- ½” Bolt (8” length)
- 3/8” Bolt threaded at the end
How to make :
Step 1 :- Long wooden block
First of all take a 39” long wooden block and make a centre line on it. Then after, make points to create holes on the centre line of the wooden block. The distance between the holes is 3”. The Diameter of holes is 3/8”. Make sure that the holes are accurate and on the centre line of the wooden block.
Step 2 :- Small wooden blocks
Second step is make a small wooden blocks. Here, 3 pcs of 2”*2” small wooden blocks are used to make a long vise. One is fixed at the end of the long wooden block and ½” nut is fitted in it to make a parallel movement of the second wooden block using a bolt. Second small wooden block is movable block. Its parallel movement is provided by bolt and nut fitted in the first fixed block. Third block is also movable according to the length of the workpiece. In the third block the 3/8” bolt is fitted, this bolt is used to fix the third block in the holes of long wooden block according to the length of the workpiece.
Now, the vise is ready to use. This vise is very useful tool for woodworking and it’s very easy to make.
