I recently bought a slide whistle. How much resistance is meant to be on the plunger and how is it supposed to sound when moving it up and down (without blowing into it)? Mine has a noise that sounds like something is scraping the inside. I'm not sure if it's supposed to sound like this or if it's just been damaged in the post.

Thanks.

  • That's the problem. I bought it through Amazon and I can't ask the supplier a question. – zx_exe Nov 7 '17 at 18:46

It is generally not supposed to make a sound.

If this one is made of metal, you can probably take it apart. You would want to remove the piston, and clean the chamber with a microfiber cloth. Then, add a VERY, VERY SMALL dab of mineral oil, if you are unable to return it. This should properly lubricate the piston, so that it does not scrape the sides enough, and will lighten the load you need to put on the plunger. Reassemble and you should be set.

If the plunger still does not move freely, I recommend going to your friendly neighborhood music store, and they will probably check it out, or sell you a replacement if they cannot fix it. Most of these stores are generally pretty honest and won't tell you that you need a new one if it is easily fixable.

  • Okay, I will try this. I live in a very small community so i'm not worried about dishonest shopkeepers. Thank you for your help. – zx_exe Nov 7 '17 at 21:27

A bit of mechanical noise is normal. If the plunger wasn't slightly 'scraping' it wouldn't be air-tight. But it should move freely.
