I put the 2 ties about 5' apart, based on what I had handy for the horizontal compression strut! My buck rail fence is getting a lot of interest from my rural neighbors and passerby, all positive. I am telling some I cut all the wood myself, plus dadoed the jacks's, and so on. Actually my fencing supplier did most of that work. I still had to assemble the cross jacks, and man handle all the material, BUT the fork attachment made that as easy as possible, still a butt load of physical labor and I'm glad it's done. About $2300-2500 cost, the log cabin screws and and other hardware being about 400 of that, to go about 700'. But in this country these type fences seem to last forever.That makes so much more sense now, thanks for the explanation. We base most fencing on eight feet post center and generally the h-brace is also eight feet apart. Why 5 foot space? More idle curiosity.
And I hate barbed wire running and stretching, always get too many nicks and scratches. Be safe
