MODEL NO 1.3
Date:
CROSS HALVED JOINT
Aim: - To make a cross halved joint from the given material as shown in the figure.
Materials required: - 50x25mm wooden reaper of size 250 mm.
Tools required: -
a) Measuring and marking tools: 1.Steel rule, 2. Try square 3. Marking gauge 4.Straight edge
b) Cutting tools: 1.Tennon saw, metal jack plane, firmer chisel
c) Striking tools: 1.Mallet
d) Work holding devices: 1. Carpenters vice, C Clamp.
Operations to be carried out: - Measuring, planing, marking, cutting, chiseling and assemble.
Procedure:-
1. Copy down the fig of the model in the rough book and collect the work piece.
2. Check the suitability of making the model using steel rule.
3. Hold the work piece in bench vice in such a way that one of the best wider sides can be planed.
4. Using the jack plane, plane the surface till the band saw mark has gone and check for the straightness.
5. Plane one of the adjacent side and check for the right angle using try square.
6. Mark 44 mm on the wider sides with marking gauge and plane to remove the excess material.
7. Mark 22 mm on the thinner sides using marking gauge and plane to remove the excess material.
8. Cut the material to two pieces each measuring 120 mm.
9. Mark the material to be removed on both the pieces to make the joint using steel rule, marking gauge and try square.
10. Using Tenon saw, cut the material to be removed to the required depth very near to the marked line in the unwanted portion.
11. Using firmer chisel, remove the unwanted material by holding the item with a C clamp and assemble the joint.
Result: - Cross halved joint of required dimension is obtained.
