Längd: 53 min. Planishing hammers are a real 'workhorse' of metal shaping process. They are unexcelled for flattening welds, working in constricted areas, and stretching flanges. Ron demonstrates the basic procedures for using these machines, including proper die selection and operator technique, and he shows their use on both steel and aluminium panels. More specialized techniques are covered too, including flanging, riveting, and making reverse curves. This dvd shows seven different planishing hammers in action, from bargain-priced entry-level machines, through vintage and hand held machines, to the most robust professional-level machines available, giving the viewer invaluable insight about the great diversity of these machines, and which features are most important for specific types of work. As popular as planishing hammers are, there is precious little information available on their proper use, and this dvd will give you a strong foundation for selecting and using the right machine and tooling for your application.
