Playing with a Bullroarer I Made a Few Years Ago. Sounds Good and Loud...

Thank you for showing an interest in my bullroarer video. A lot of people have asked me to provide the dimensions of the Bullroarer seen in this video. I tend to make objects like this, impromptu. With saws knives and sand papers and no rulers, finishing it with flat surface sanding. I just make them by eye, shave and test and shave and test. That one was quite heavy... I say "was" because in my first attempt to do a "Bullroarer from across the water" video. I was using the one in this video. The Camera was set up and I was on the other side of the body of water. I got a good drone going, nice and loud, then, the cord snapped. And the roarer seemed to slowly fly down then back up, like a feather on the wind, then dove into the water. Shot down to the bottom of the river and I lost sight of it. I jumped into the kayak and tried to see if I could find it floating down river. I checked logjams and eddies for a few miles. It was gone for good. So I made a new one. The sound was, unfortunately not as loud as the last one. As seen in my second attempt at an over water video. http://www.youtube.com/watch?v=nme5CXfXPWc
I made the changes I needed for a new video to replace the one in the link. A third attempt video is soon to come.

The Dimensions of the this one are strictly from memory. It was cocobolo that had some good weight. It was tapered where the cord was attached and flat on the other end with rounded corners. It was 30 cm long and 5 cm wide, give or take. It was 8 mm to 1 cm thick with tapering edges to maybe 5 or 6 mm all the way down. A cross-section would look like a flattened hexagon standing on a point. I hope my description of it's shape is clear enough. Best types of wood to use are heavy hardwoods. Fire damaged Blood Oak in Australia was often used. I have a tiny scrap of that. I never worked it because it's very thin and 10 cm long by 50 cm wide. Just like pines and cedars it would be too light and wont allow good momentum when spinning. Lignum Vitae is another hardwood I have used. It stays nice and sharp and it is solid as a rock. The sharp edges help increase the volume as well. Then I just finish it with a wood oil of any type. That one was scrap wood I picked up for some flutes that I had been making. It had a beautiful marble pattern. It also had rare wormhole damage, which helped increase surface area for more sound. The cordage was braided artificial sinew at about 2 meters.

I was very bummed out when I lost it. It was a good one. I hope this information is helpful to you in building yourself a nice Bullroarer. It's quite simple really and I would very much like see how it turns out.
