I have a 10” HF DP that vibrates a little too much. Running the motor alone, with belts removed, it runs very smoothly. The pulley system has 3 assemblies. The center assembly pivots, but is kind of floppy, like side-to-side floppy. Is this the way it should be or should the assembly be stiff enough to hold 90* or parallel with the other 2 assemblies?[URL=][IMG][/IMG][/URL][URL=][IMG][/IMG][/URL]

You will find the belts that come with much of the equipment from overseas leave a lot to be desired. My drill press, jointer and bandsaw all had the same noticeable lump in the belts leading to vibration. If you want to spend the money the link-belts will reduce or eliminate this vibration. A less costly option is to use the cogged belts which are generally available at the auto parts stores. I used the cogged belts on my bandsaw and jointer with noticeable improvement. For the drill press, I had a length of link-belt I received for free from someone at work and made the two belts from that. This reduced the vibration and flopping of the center idler pulley assembly. Whichever route you choose to take just make sure you are replacing with the same width belts, usually ‘A’ or ‘B’ width.
