Hello everybody, i just had a bow break on me. it broke on the bottom limb so i cut off from the broken part to the handle and made an atlatl with the top limb. I'm looking to do something with the bottom limb and i was thinking of making a bullroarer. You guys have been very helpful and i thought i would ask. Thanks in advance!

What is a bullroarer?

It's a aboriginal musical instrument that is swung over the head to make a deep throated roar of varying pitch depending on the speed at which it is swung.

A Bull roarer is an indigenous cell phone! They have been used by primitive people around the world for communication. They have been mades in various shapes and sizes. One was used by paul Hogan (crocodile dundee) in his movie. Typically made of wood or bone. fairly thin usually not more than a quarter inch or so. 12 to 18 inches in length. rectangular rounded on the ends and beveled all the way around. drill a hole in one end and tie on a leather or heavy cotton or dogbane cord. I will take pics of the one in the musuem and try to post later. I have been having trouble posting so might have to wait till I get home. Have fun with theat and don't hit yourself in the head!

It may not be primitive but a braided nylon string is best to use for the bull roarer. The board is not only rotating as you swing it but it is spinning on the string's axis. When the string gets tight going one direction the roarer switches directions of spin until it gets tight going that way. It wraps back and forth as long as you keep rotating it. the pitch changes each time it switches.

You can make them out of most any hardwood but denser is better. Oak, osage, hickory, etc. avoid soft woods like pine, cottonwood, etc.

Have fun and paint it up real nice!

WHOAH! that thing is huge!

Like a paddle without its handle. Does it sound different than a smaller model?

Don't guess I have heard the smaller one,it has a pretty deep roar.Sounds awesome.
