You may remember my post regarding a Utube video of my restrored Parkinson Power hacksaw. It was suggested that it was running in the wrong direction. It was recommended that I time it cutting in both directions , and the direction that cuts the fastest is the correct one. I timed it in the "backward" direction and it took some 12 mins to cut through a 100mm x25 mm flat bar , on the flat.The blade was cutting on the backward stroke . Up until today I was waiting for my nieghbour ,who is an electrician , to change the direction of rotation of the drive motor .Well today I finaly collared him and put him to work ,the rotation was reversed . I checked the lift before cutting and found I had to flip the blade around so the teeth pointed forward as it was lifting on the back stroke and dropping on the forward stroke. Any way it took just over 4 mins to cut through the same material and down feed setting as before so I guess this is the correct direction . It's just a bit strange to me as all the power hacksaws I have ever used cut on the back stroke to ward the fixed side of the vice.
