Tool Holder To test you understanding of the assembly process, copy the contents of the tool holder folder (located on the shared drive) to a folder on your memory stick or P drive.

Using the parts provided in the Tool Holder folder, create an assembly and drawing. This drawing should include Top, Front, Sectioned and Isometric views as figure 20.

Create a Table and Bill of Materials and label appropriately

Use figures 17,18, &19 as a guide for the placement of parts.

When both drawings are complete they should be saved as PDF files and submitted via email (see last page of this tutorial).

Please keep this exercise for future reference as it will NOT be reissued.
