DIY stereo bar (on budget)
Ingredients: - unperforated, zinc-plated steel DIN rail (available in electrical supply stores or TME) - 2 K&M 3/8" thumb screws (available on Thomann) - 3 K&M 3/8" thumb wheel (available on Thomann
Tools: - drill for making the holes in the rail - 9mm drill bit (but you can use a smaller one and extend it manually)
Total cost: ~6€

- 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.
