Jonathan i think you need to learn some safety. Extending the lenght of the cutter using an 8mm bar seems an extremely dangerous thing to do. You are not wearing any safety gear (Full Face Shield) would be a good idea and ear defenders, i know to my cost how stupid it is not to wear ear defenders .

My guess is centrifugal force took over and bent the bar not the power from the stepper,there is a reason that the cutters are not too long, and that is for safety/stability reasons. I'm sorry if i seem to be having a go at you personally but you seem an accident waiting to happen.

So this rant is also aimed at the people who think machines running at high speed are safe, they are not especially when you modify them to be even more dangerous.

The last thing people on here want to hear is of you having an accident or anyone else for that matter.

Rant over
