Press-fit Knob Inserts - Easily Make your own guitar knobs!

This is a set of five (5) black plastic knob inserts you can use to make your own custom guitar knobs! These press-fit inserts have raised ridges and fit nice and snug into a 9/16-inch (14.3mm) hole (though a little superglue or contact cement wouldn't hurt). We recommend getting yourself a 9/16-inch forstner bit (or nearest metric equivalent). Using a drill press (even a small bench-top model) really helps with being able to drill nice straight holes of specific depths also. These inserts are 1/2-inch (12.7mm) in height so not a very deep hole is needed.

You can make your own knobs out of old bottle caps, pieces of wooden dowel, and many other things... you can even laminate thin strips of different-hued woods together for a very nice effect. For more exotic knob-making supplies, take a look at sites that supply pen and knife-handle makers... they have lots of great stuff to spark your imagination.
