Numpty, get yourself a Donald strainer. They are top quality and will last a lifetime. My old one has strained hundreds of miles of fence.
You can make a strong spinning jenny out of timber, just give it some thought to be sure the wire doesn't rise above the short posts on the
jenny and come off !! Have NM put a foot on it so that it doesn't get out of control.
Also get yourself a good set of pliers, farmers and fencers use the ones about 13 inches long with no plastic or rubber grips on them.
For twisting the wire around itself to tie it off, cut a piece of flat steel
about 7 inches long, inch x eighth. Drill a hole a bit larger than the wire about an inch from one end. Fit it over the end of the strained
wire and wind it around and around like a tight coil. Easy. With a bit of practice you can make a similar tool to tie off barb as well.
For running barb the simplest and quickest way is to just tie off one end, put a crowbar thru it and the two of you just walk it out unrolling as you go.
You can do it this way on your own if you are fit enough.
Wear leather gloves.
Keep your canvas water bag topped up !!
Have fun.
