This is a result of a test of the tooling for manufacturing a new range of Victa lawnmowers designed by BlueSky Creative in partnership with Victa Lawncare Pty Ltd in 2002-2003. This test piece represents an important part of the design and manufacturing process - the design and construction of the tools and dies from which the final product is made. This test piece was made by G. A. & L. Harringtons to test the tool design for pressing the mower deck from sheet metal at 50% scale. It shows that the test failed because the sheet metal ruptured during pressing.
