The bolt which locks the toolpost in the harp snapped off on my 3520. I had extended the lever with a 6" wooden turned handle and it worked fine for the last 450 bowls/vases. The original lever at 3" just was too difficult to properly tighten. Of course the toolpost was locked into the harp as well. So after a few choice words I spent the next 2 hours drilling it out and retapping the hole. Now I have a temporary bolt in there which is tightened by a crescent wrench. Has anyone else had this happen, and if so what did you do to fix it longterm?
