Rik think it was you that I suggested Fishing Line to hold your Logs on the new Feldbahn Wagons you got. If not you sorry but this post should be found by the right guy.
I use 2 methods for holding Logs together. Essential when Loads are removed for Empty return to the Loading Point.
Method 1
I started to use Mains Copper Wire hammered flat and wrapped arounfpd the Load. This is not the best of methods as the loads can sometimes be a little loose, bodging in more wood to make the Load nice and tight helps. This method is still in use and the Loads are used regularly still. Does not look to pretty underneath but from normal viewpoint is fine.
Method 2
is Heavyweigyt circ 20-30 lbs Breaking Strain Pike Fishing Wire, this is Metal Braided Wire and cimes on Reels. Crimps are also supplied for this to end the Wire and are Threaded with the Wire and Squashed up with a Pair of Pliers.
