I once saw, on a website, a tool to make your own snake guides. It was a two piece block of metal in which you placed your own selection of wire material and somehow it formed the snake guide. I believe the form sold for around $40 and was able to make only one size guide, so one would need to purchase several, depending on your individual needs and rod specs.
Problem is that I can not seem to locate this tool any longer. Can anyone help me locate this tool?
