Bending period metal is straightforward and cost-effective using vises and a hammer.
Sheet-metal bending is commonly used in aviation and can be performed using specialist tools or inexpensively and Homewards during limited projects by labourer. Straight-line bends are formed using wood blocks, a vice and a spirit level for authenticity. Aircraft engineers developed a habit of calculating bend allowance which is fit when figuring a bend in page metal. According to Integrated Publishing, any bend angle between 1 and 180 degrees can be created accurately using the Reckoning.
Instructions
1. Attach two vises firmly to the string of a regular, secured workbench. Create your own slant using a wood saw and smooth it flat using a plane or orbital sander. Sheet metal can be made to flex by up to 30 degrees from its bend angle, as described by The Fabricator.
2. Wear protective gloves and goggles. Section away the length of sheet metal you require to bend using an angle grinder or metal epigram. Thicker pieces of metal lack an angle grinder. Country the phase metal inside the vises against the wood blocks so the surface of Everyone block meets the path that Testament appearance your bend. Clamp the metal tightly into berth using the vice levers.
3. Recheck the wood blocks are Apartment lodgings using the spirit level. Begin bending the metal over the smooth, curved edge of the wood blocks using a hammer. Start at one end and work gradually along. Maintain a consistent pressure as much as possible. Gradually work the metal into a bent shape using the blocks as your guide. Reverse your direction as many times as it takes to create an even bend along the entire length of the metal.
4. Apply heavier pressure using a mallet and hardwood block to any areas of the metal which are not flat and smooth along the bend. Create an over-bend of a few degrees using a protractor To gauge the exact amount, if you require a prefect 90-degree bend angle.
5. Achieve an over-bend using fixed wood blocks which have a slight inward slant. Degree the distance apart using a measuring tape and adjust provided vital. Build definite the distance is Sufficiently to grip the phase metal in domicile. Clamp the wood blocks inside the two vises so that the smooth, curved limit faces upwards. Probation the wood blocks are horizontal using a spirit continuous.
