Today, I got serious about building the lift from American Woodworker-March 2004. They list a couple of suppliers, but I have found a local supplier for 3/4" polished rods. Their reccomended supplier is in Nashville TN, so the freight is almost the same as costs of rods, but they will cut them in half at no charge. The local ones are 35" long instead of 3'- you lose 1/2", no big deal. For the bushings, MSC has them for $1.60 each, while local supplier is $4.60 each. Each lift needs 4 bushings. MSC has a minimum order of $25.00. The first of next week, I will be placing an order (I need some other things). If you think you might be needing some of these bushings, let me know and I will try to order extras.
