Yes, I am tired of using a torch to bend the pedal cranks out for clearance for pull-start and centrifugal clutches, so my plan is to use a rewound microwave oven transformer controlled by a variac to heat the crank to bending temperature.
To give you an idea of what I am talking about

Of course, the variac will be uses to control the output so that there will be some element of repeatability and safety when using such a technique.
Anyone ever try such an approach?
