Method for bending a tight set in solid bar

[swedishchopper]

Hi All

This is a method I use to bend solid bar which works really well when a tight radius is required. I had to put a set in a piece of 12mm diameter bar for the handle on my retractable screw cutting tool holder. (for three reasons) To give better vision when external screw cutting, secondly to move operators hand further away from the chuck when retracting the tool and thirdly to miss one of the clamp screws.

Method;
Firstly, you notch with a file where the inside radius of each bend will start along the bar. In this case I also had to take in consideration the orientation as the bar screwed in to a housing. The bar can then be set in the vice with the notch vertical and at the edge of the vice jaw. The bar is then heated until red and a piece of tube slid over to aid leverage to bend the bar. Due to the notch, this is where the bend will be formed about. The process is repeated for the second bend to create the set.

First photo shows notch cut with the bar screwed into the housing so the orientation of the handle is correct

What's the gas nozzle you are using for heating? and what type of gas are you using
