Barbed wire rig (invention)

I was looking for a way to stretch four strands of barbed wire at the same time but did not want to spend a lot of money.  I have taken a woven wire unroller and modified it to stretch four strands of barbed wire at once.  I could possibly add another roll to the device to stretch five strands at once.  Watch and see this simple modification I made to the unroller, which can still be used to install woven wire fencing.
