My scroll saw is broken

My scroll saw developed a knocking noise which got worse with increased speed. I asked advice on the scroll saw forum and tried the suggested fix--to lengthen the rod that attaches to the tension cam. To my dismay, not only did the noise not go away, but the rod jammed and I couldn't put the saw back together. Fortunately, the shop member who is responsible for repairs called a DeWalt technician, who came on Monday, and discovered that there was a broken part at the rear of the arm which had been causing the noise. He took the saw away, and will be bringing it back on Saturday. In the meantime, I'm using this "down time" to prepare some new blanks so I'll be ready to go. I'm glad I'm under no time pressure, but the empty stand looks so lonely as it waits for the saw to come back.
