Hi Dan:
Thank you. The track plan is somewhere around 75ft +/-, enough that, like Bruce, the materials need to be inexpensive and locally acquired. Everything but the wire is from Lowe's or HD, including the 3/8-24 threaded rod you correctly noted. The 125ft 18g copper spool is from SmallParts. All of the cat support masts are bolted to the table over a metal plate. Otherwise the wire tensioning would bend the supports into the benchwork. Some days progress was '3 steps forward, 2.9 steps fixing things you should have foreseen.' I'm typically not inclined to share projects until they are more operational, but after Bruce's post I couldn't help myself.
