Gary, the way they use the plow discs is to keep the rolls separate while unrolling.
Thirty years ago I bid on a great big job, hundred miles or so. It was five strands of barbwire with t posts and braces in California. When I went to the pre-bid I realized I'd stepped out of my league. This was a phase three of a continuing job. The boys doing it had miles of experience to work out the bugs.
What they had was wire holder that held tension along with a post driver. This was on a small crawler, D-3 if I remember right. They had one crawler clearing the right of way and setting braces. That was followed with the wire dispenser post pounding rig. A third crawler followed doing clean up.
Here's some ideas for you to consider.
One, the pilot rod should be hex bar. Then the separator plates should have hex holes to match the bar. I would weld tabs on both sides of separator plates that will grip the rolls of wire. These could and should be short so that they engage only the wire frame and not the barb wire itself.
Two, I'd want the hex bar to have a mechanism that allowed the tension to be adjustable. I'm thinking a sleeve that fits over the hex bar and with a coarse acme style thread with threaded collar to tightening. For tension I'd rig a disc brake assembly like that found on small motorcycles or go karts. Cable would work, hydraulic would probably be better.
The hiccups are of course uneven terrain and different factory tensions in the rolls of wire. This might be compensated for with a stand off rod or bar like that found on the Wire Hog or a comparable product.
A friend of mine does a lot of farm fence and he just uses pipe with plow discs for separating so if you're not going to make this job a career that might be the place to start.
James, I'm glad you like the wire unroller. I heard the other day people are now buying shirts without pockets. What's this world coming to?
