I get flat wire on 20" x 6", 12" core wooden spools. Sometimes they are wound poorly or I need lighter spools for a repair machine. I rememberreading a post years ago about a traverse for winding. I remember it had a DC motor with a pot to adjust speed but that's about all. I don't need a PLC to adjust for height on the core or perfect alignment of the wrap. I found that a basket weave works great for tangle problems and eliminates having to precision wind. Any ideas will be highly appreciated!
