homemade mechanical cow....with small pulley

This is how I made a mechanical cow for cutting training....the white pulley end is set up with a chain so that I can easily tighten the rope if it sags too much.. just move the links over on the hook to tighten....the motor is a marathon instant reverse motor which cost about $280....the controlling switch is a 9 pole reverse switch which cost about $23....the side of the motor tells you how to wire the switch..I use different size pulleys on the motor to change speed...smaller pulley (1 1/2") for slower and larger pulley for faster...it takes less than 1 minute to change the pulley out..total cost including rope , pulleys and wiring was about $360.00...you need 5 wires to wire up the 9-pole switch...I used an old extension cord and added two wires.....4-17-2014...please email questions to [e-mail]...I can't seem to reply to questions directly on youtube for some reason....
01/01/2017....Wow I never thought this would get so much attention...just wanted to let folks know that I now have pictures of the wiring of the motor and switch available....just email me at [e-mail]...
The motor is: 1/4 hp Marathon instant reverse 1725 rpm, 115v
The switch: amazon.com/Power-First-Toggle-Switch-Maintained/dp/B001QROZUW
you will also need 5 strand wire…I used an old 3 wire extension cord and added two more wires to it….
I just googled the motor and found this:
www.zoro.com/marathon-motors-...
I got mine off amazon but I don’t think they have it anymore….they listed some third party sellers but they were higher than the above….
The pulleys on the motor I got at TSC - Tractor Supply….I got the rope and plastic pulley at Lowes….if you want the spring mounted with the plastic pulley TSC had some of those in the nut/bolts section on an end display…..I used a spring I had laying around from an old screen door …
The flag is a silk neckerchief folded over and attached to the rope with safety pins…it hides the knot where the rope ends are tied together…I placed a piece of rope in the fold to help hold it down while it goes back and forth,,, the spring and plastic pulley assembly is attached to a chain so that I can tighten it easily if the rope stretched.
The switch box is just an electrical box with front plate on it and the switch mounted to the front plate.
The motor has the wiring schematic on the side of it….the only thing that was somewhat tricky was what position the switch goes…it has three rows of three connections….the first time I wired it was wrong and I tripped a breaker when I flipped the switch on….I turned it 90 degrees and rewired and it worked fine…
