MAKE A PROCESS FLOWCHART :

PROCEDURE:
Pattern Making

1. Using try square check the perpendicularity of the wood
2. Using try square and steel ruler check the dimension of thewood if it is suitable for our

design if not either replace the woodif it is less than to the required dimension as specified

in our drawing if it is greater usingrip cut saw reduce the wood to its suitable size

1. Divide the wood into two (2) parts using following procedure(either)

a. Create two diagonal lines, theintersection points of the two diagonal lines represents the centerof the wood then marked the center and draw a lines (represent aspt P)

b. Measure 60 mm from left side thenmarked the point at 60 mm and draw a lines (represent as pt P)

1. Using rip cut saw cut the wood into two (2) piece, cut locationis in step # 3
2. Overlap the two (2) piece wood then around the side of thewood, tape the wood using

masking tape for temporary joining ofthe material

1. From the top side of the wood create two (2) diagonallines
2. Get the center of step # 6 from the center create a point goingdown by 10 mm (represent

as pt O)

1. From pt O using compass create an arc with a radius of 10mm
2. From the center using a compass create an arc with a radius of38 mm
3. From the top right side of the wood from the edge measure 28mm
4. From the lower left side of the from the edge measure 28mm
5. Connect the arc and step # 10 and step # 11 to create theoutline of the elbow
6. From top right side of the wood measure 14 mm then offset goinginside by 15 mm marked

it using a pencil it represents as thebamboo pin location 1

1. From lower left side of the wood measure 14 mm then offsetgoing inside by 15 mm marked it using a pencil it represents as thebamboo pin location 2
2. Using drill make a hole for step # 13 and step # 14
3. For the drill bit use 1/8” diameter then measure 22 mm depth ofthe drill bit then marked it

using masking tape it represents asthe limits/depth of the bamboo pin for our pattern

1. Remove the masking tape around the wood
2. Then placed the bamboo pin to its location

Base

1. Secure the wood piece in the bench vise
2. Using compass draw a circle at the side of the wood piece, thecircle shall be connected to

the step 10 and step 11 of patternmaking

1. Using rip cut saw remove the part of the wood outside theoutline
2. Then to shape up the wood into elbow using set of files such asrasp file, small file and

triangular file form the elbow makessure throughout the wood it should have 28 mm in

diameter

1. Using sandpaper clean the surface of the base

Core Prints

1. Using the other wood create the core prints 1 and 2 (CP1 and CP 2); using compass drawthe circle with a diameter equivalent to 32 mm and 28 mm.
2. Using rip cut saw cut the core prints (CP1 andCP2)
3. Using set of file form, the circle of the core prints
4. Using set of sandpaper clean the main body and core prints(CP1 and CP2)
5. Using wood glue attach the core prints to the main body withfollowing arrangement as shown in drawing
