Homemade hack saw

[Hardly]

Josh,
Can you expand on how your auto shut off works?

I need to make something for my Marvel.

I have an old craftsman power hacksaw. I used a switch off a wayne upright sump pump. I mounted it on a piece of 1 1/2" angle iron that was slotted so I could move it up or down to change the shut off point. The lever of the switch sticks out about 1 1/2" and contacts the bottom of the carriage as the machine cuts and the carriage lowers. I have it set to shut off just after the cut if finished. The reason I went with this type of switch instead of something like a limit switch was that after the cut is made you have to manually reset the switch for the machine to restart. I was afraid that if I used a limit switch someone that wasn't familiar with the machine would pick up the carriage, without shutting off the main power switch, and it would scare the bejesus out of them and possibly someone would get hurt. There is probably a better solution for a switch but this is what I happened to have and it has worked very well for years.
