I just purchased used a 2004 16HD (non-Baldor). It is a beautiful machine . I need to run 220 and work through issues related to the machine sitting for years. I felt that I got a good deal $1100. Anyway, I intend to buy a new 1/2" blade and get the Resaw blade it came with resharpened. The only defect I really want to address is the tires. The upper tire is a bit chewed up. Does anyone have ideas on how to replace? Thanks. Ted
