5 steps to Marking out �Face side / Face edge �Overall Length �Joint Position �Joint Detail �Any other Detail �FOLLOW THIS PROCEDURE AND NO OTHER!!!!!!!

The different parts of the digger

Orthographic Projection

Step one: The Body The 4 pieces for the body and the piece for the bucket will be market out and cut from the 44 x 44 piece

The cab and arm block � The cab is 80 x 44. The slope needs to be cut on the bandsaw and smoothened down using the Belt sander �Arm Block 22 mm 6 mm 22 mm 25 mm 40 mm 50 mm Diameter 6. 5 mm

Glue the Body

Step 2: Marking out the arms 2 of these arms are needed 25 mm � Mark out angles to allow the arms close. Measure down 15 mm either side.

Step 3: Tracks � Mark out the trench and curve of the tracks, the trench is 10 mm deep 40 mm 70 mm 25 mm

Step 4: Spacer between the body and tracks �A round spacer is needed between the body and tracks to allow it spin. Screw is used to fasten the body to the tracks

Step 5: Mark out the Bucket � Once the tenon is marked out you must free hand sketch on the shape of the bucket 6 mm 25 mm m 19 m

Preparation for finish �Using the belt sander and sand paper and the sanding block, sand the whole digger down using the different grits of paper. Make sure all pencil marks are removed

Assembly

Choose from which finish you prefer. �Varnish �Danish Oil It would be better to disassemble the project, apply the finish and re assemble.
