Metal Shaping Options in Making a Complex U Shape

- Lazze demonstrates the differences between two different techniques to make a very similar part. One technique uses the english wheel and 'a rubber band,' made from a truck innertube, and the other uses the english wheel, shrinker and stretcher, and then the english wheel and rubber band.

Great instructional video. I'm just starting with an English wheel anhydride your videos are a great help to me.
i see so every stroke of the wheel is like a slight bend in a brake? very cool , ive seen this device in the past having no clue how it worked , thanks for posting
Awesome stuff. Thanks Lazze. :)
Lazze thank you for your how to vids. They are very helpful. Gary
I'm really interested in metalshaping, thanks for the videos Lazze. Can you make a video how to achieve these type of results using hand tools?
There are some great videos on RUclips by others showing how to by using hand tools. My technique doesn't turn a smooth piece of metal into one that looks like a bag full of potatoes then back into a smooth piece of metal again. You'll see some hand tool work sometimes at the end of as things are getting minor adjustments, but that's about it!
I love that technique!On a piece of metal the size you are using,approximately how much "pre-stretch" can you get away with before the slip-roll type work?I'd like to make a panel similar to this,but with a much more pronounced long-axis curve.Basically,like a motorcycle fender as mentioned by another poster below?Thanks again for posting these videos,they are a great inspiration! I am in the process of building my own English Wheel,and can't wait to get started making stuff!
Thank you for your comments. The amount of pre-stretch depends on the material, and tools you have access to. There is another video you could watch which may help with deciding the technique, and while it isn't exact to what you are doing it might help: ruclips.net/video/jYzOwWNZIME/видео.html
Thanks fot the video! Is that how you make a motorcycle fender?
That could be one of several ways to make a motorcycle fender shape. It depends on what equipment and material you have access to. There are usually many ways to accomplish the same goal.
Nice!! Thank you!!
Hi Lazze,
Great demonstration and much easier than using the slip roll.
The real difference between shaping with the rubber band and without, is using the rubber band is "forming" and not using the rubber is cold "forging". Great video and wonderfully insightful technique.
Forming and forging - maybe cold press forging to be more accurate?
With a slip roll the result is curved only on one axis, with this technique, it can be curved on the second axis as well.
To describe this differently, because someone else will have a similar question, think about the structure for a tunnel - the material holding the shape; with a slip roll you would end up with a tunnel that is straight through from one end to the other; by adding the rubber band to the process the tunnel can curve up or down, and we'll have to try it on video some day, curve left or right too.
This can also be used on much smaller pieces of material, and with less waste. rather than making the shape and then cutting off the material that was required so it could be secured in the slip roll.
