ABOUT THE PROJECT
When making the oil sludge, neat and flattened slits should be scraped. However, the available tools at the time were not sufficient to accomplish that. I made some improvements on the ordinary needles through manual work with the support of the electric grinding wheel combined in the processing. Upon grinding, the thin slits can be scraped out of the oil sludge quite conveniently, making the model more classic and graceful with the scrupulous attention to details.
