Think about your safety when using your bender.. what happens if you have a failure... currently you are setting yourself up for a serious injury... think about a remote switch that allows you to step away from the work... as shown you are all tangled in it...
I have a foot switch,,, a 6 foot cord,,, and safety glasses all the time
update.. I see the brothers already made this suggestion.. remember how much load the thing is under.. (hear it creaking?)... you have to reset pins.. I was wondering about that.. on mine (jd4hd),, I just keep on bending.. no reset
