  - Adjust the size of the rail to your liking. For a 40 cm AB stereo bar I went with 42.5 cm.
  - Drill the three holes in the top rail. For 3/8" you can use 9mm drill bit on the sides and 10mm on the central one. On the sides, the closer to the internal diameter of 3/8" you'll get, the better.
  - Screw in the screws into the holes and use thumbwheels as washers, protecting the screws from falling out. Alternatively you can use M8 retaining rings for shafts.
  - Use the third thumb wheel as a way to tighten the bar to your stand. You can epoxy-glue the wheel to the bar to attach it permanently.
