Question

MAKE A PROCESS FLOW CHART :

PROCEDURE:
Pattern Making

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

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

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

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

a. Create two diagonal lines, the intersection points of the two diagonal lines represents the center of the wood then marked the center and draw a lines (represent as pt P)

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

4. Using rip cut saw cut the wood into two (2) piece, cut location is in step # 3
5. Overlap the two (2) piece wood then around the side of the wood, tape the wood using

masking tape for temporary joining of the material

6. From the top side of the wood create two (2) diagonal lines
7. Get the center of step # 6 from the center create a point going down by 10 mm (represent

as pt O)

8. From pt O using compass create an arc with a radius of 10 mm
9. From the center using a compass create an arc with a radius of 38 mm
10. From the top right side of the wood from the edge measure 28 mm
11. From the lower left side of the from the edge measure 28 mm
12. Connect the arc and step # 10 and step # 11 to create the outline of the elbow
13. From top right side of the wood measure 14 mm then offset going inside by 15 mm marked

it using a pencil it represents as the bamboo pin location 1

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

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

17. Remove the masking tape around the wood
18. 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, the circle shall be connected to

the step 10 and step 11 of pattern making

3. Using rip cut saw remove the part of the wood outside the outline
4. Then to shape up the wood into elbow using set of files such as rasp file, small file and

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

diameter

5. Using sandpaper clean the surface of the base

Core Prints

1. Using the other wood create the core prints 1 and 2 (CP 1 and CP 2); using compass draw the circle with a diameter equivalent to 32 mm and 28 mm.
2. Using rip cut saw cut the core prints (CP1 and CP2)
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 with following arrangement as shown in drawing
