I bought a 1930’s style big hole no name whistler off ebay for $9. Can’t get her to sleep long enough to whistle. I am thinking the axle is prolly a little ruff. How could I sand it? With a worn out string and some kind of sanding compound?
I also bought a new YoYo factory whistler. Well she whistles, but not very loud at all. Any solutions. I thought of angle drilling the holes the same size as they are so they would catch more air.
