Hello all, I misplaced the outside blade washer for my Bosch 4000 TS while using my dado blade. I went to 2 local tool repair shops and one did not have it in stock but offered to order it for me. The second was lessthan helpful. Went on-line and found http://www.ereplacementparts.com /. Prices were excellent, reasonable s&h and fantastic customer service. I try to buy locally when possible but I'm very happy that there are companies on-line that give excellent service. Of course, I'm not affiliated with them-just a very happy customer!!!
