After watching one of Jose Rodriguez teaching CD's and seeing his little Sieg built lathe outfitted with metal change gears, I tucked the idea of owning a set in the back of my mind and kept my eyes open. I stumbled onto a web site offering them recently and ordered them today. This guy also offers a range of metal gears for these little machines, including a full set of replacement drive gears with the change gears at a discounted price. His products can be seen at https://thehobbyistmachinestore.com/catalog/products.php?cat=8 . I spoke with him when I placed the order and he seems to be pretty straight up. Said I'd even have them in time for the wife to find them in her Christmas stocking. I do love buying things for that woman. Steve Who will soon have a nice selection of plastic gears to use for indexing tools.
