Power Hacksaw 

The main problem with constructing a DIY power metal saw involves the correct slow speed drive to the crank. Washing machines use an electronic control to do this task. This saw also uses the drum bearing and a cycle pedal to provide a reliable machine. The 1000watt AC motor has ample power and constant speed when controlled by the  TDA1085C. The inspiration was from our friends across the pond 

This shows my saw in all its splendour and you can build one very cheaply as I did. I use it making my support chair. OK, junk is just good stuff in the wrong place !! Plans available now. Now Free download !!!
