I am building a 2 3/8" post and cap rail fence. It will have 4 lower rails of 1" sucker rod. Anyone have any good ideas or photos of jigs they have built to keep their rail spacing even distance from top rail? Needless to say I have a lot of fence to build and am looking for a faster way to place my rails , other than measuring out each onc at each post. I hope this makes sense! Thanks in advance!
