Lately, I’ve been trying to learn how to use an English wheel to fabricate parts with compound curves. Creating compound curves in sheet metal is about changing the thickness of the metal. Showing how to use one properly will help me get a better idea of how I should be using this. If you look down on the roof of the car the panel curves (from center to edge) away from you in both the front to rear direction and the side to side direction. Plus I am referring to fabricating of small sized repair sections in non structural vehicle panels such as wings, bumper valances, doors etc. The best way would be to “cold mold” it from smaller pieces. RÜNGE CARS. Forming compound curves is really nothing more than knowing exactly where the metal has to be stretched and how much. Not really weakening the metal as we only use engineering scribers that make tiny but visible scores in the ~1mm thick sheet steel. Cutting in a straight line with tin snips is easy. I looked at some photos on the net and that section looks like a reverse curve. Thanks for posting this information for sheet metal bending. In the space available here we can only say that shrinking amounts to compressing sheet metal by forming into it a series of large, smaller and then even smaller crimps, such that an acceptably smooth surface is achieved. Show more. the directions of the two curves forming the compound curve oppose one another. Especially on 1100. So the ability to form sheet aluminum into compound curves requires knowledge of the process called shrinking. Metals have an elastic limit that needs to be exceeded in order to get the plastic flow to occur to effect this thickness change. Metal shaping: compound curve - building the top of a fender by Outlaw Edge 7 months ago 19 minutes 60,498 views. There is usually much more stretching than shrinking done, but shrinking can also be done with a hammer. That will help make fabricating my metal … Aviation snips, also called tin snips or compound snips (even though they are different), are the best hand tools for cutting sheets of metal. Call us with your specific requirements. Више симиларних аудио књига: Metalshaping Fender Compound Curves. With years of steel bending expertise, Chicago Metal Rolled Products can create compound curves from the lightest to the heaviest steel sections of structural steel, sheet and plate. Compound Bending Capacities. That said you can torture thin plywood a bit and these are quite easy curves so you may be able to make a form and laminate a couple of layers of 1/8” or something like that.
