Some of the attachments are limited in capacity, so I continue to use my shop built rig. Plus the issue of will it work on my saw, and I question if they are all that accurate. Also the sliding attachments are expensive if used only occasionally, at least to me. While I would prefer to have a proper sliding saw, shop space and limited use stops me from going this route. I built mine so that it uses both of the slots made into my saw top. I use a crosscut slide table or sled on my Powermatic fairly often. It has been called a sled for many years, most shop magazines will have a plan for it. Why do you want a slider? What kind of joinery do you use? Do you need a full 8' capacity? These are important things we need to know. If you are a professional don't waste your time. Is this unheard of? I have some ideas but was wondering if any of you guys have ever done it and if so could tell a little of how you done it. I'm not interested in getting a sliding table saw. I only have a Delta Unisaw right now, but am getting ready to make new extension tables for it and would like to incorporate a homemade slider for cross cutting plywood.
