This "Aussie Round" is an absolute HONEY of a boomerang.
It does a wonderfully predictable 70' circle and then hovers directly down from about 40' above you. Very, very nice. The plans called for it to be weighted, and I have taped coins on occasion. The extra weight increases the flight circle a bit and makes it better handling in the wind, but for day-to-day flying, I use it unweighted.. | |

See me throwing a Colorado Boomerangs "Condor Comp." (2005Nov26)
(this boomerang sadly, is now lost in an oak tree in the park next to my home.)
This was the first boomerang I made.
Constructed of 5mm 5-ply birch plywood, this
was a good flyer despite the fact that I didn't know what I was doing,
and that I used material too heavy to make this a real "MTA" (maximum time
aloft) boomerang. Live and learn. | |
| 11 Oct 2003 - Ted Bailey MTA |
And this is my first boomerang 8 days later.
As you can see, this boomerang has a crack
at the elbow from hitting the ground too hard on launch. Whoops. | |
| 19 Oct 2003 - Broken Ted Bailey MTA |
The first step is to transfer the pattern from a cardboard blank
onto the sheet of plywood. I downloaded all the patterns for boomerangs
used on this page from the French site, Boomerang Passion. Here, I've laid out two right-hand boomerangs.
(yes, lefties have to have their own boomerangs, since these things have airfoils). | |
| 19 Oct 2003 - Boomerang Layout on 5mm Plywood |
Using an electric saber saw, I cut the pattern as closely as possible so as
to minimize the amount of sanding/filing. Purists apparently use manual tools
for boomerang construction. Using power tools, one can have a finish-ready boomerang
in under two hours.. | |
| 19 Oct 2003 - Cutting Boomerangs |
The next step is to rough out the airfoils. I use 60 grit sandpaper on an electric
sander.. | |
| 19 Oct 2003 - Ready For Airfoil |
Using my first boomerang as a template, I draw out what will be cut away.. | |
| 19 Oct 2003 - Airfoil Detail |
And this is what it looks like after roughing with the power sander.. | |

Hand-sanding with 150 and then 220 grit sandpaper follows the rough sanding.
Here are the sanded, unfinished boomerangs.. | |
| 19 Oct 2003 - Finished Sanding |
I use 50/50 modelling dope as a first-coat sealer. This dries quickly and
is sanded down using 220 grit. | |
| 19 Oct 2003 - First Finish |
Some 000 steel wool work and the surface is finish-ready. | |
| 19 Oct 2003 - Finish Prep |
The artist is using acrylics to transfer the pattern she first drew on paper. | |
| 19 Oct 2003 - Chicken Stick Artwork |
Here's a close-up of the head of the bewildered chicken gracing the "Chicken Stick". | |

I chose to simply spray some Rustoleum onto the bottom of the other boomerang.
If I had it to do over, I'd've chosen a less gross finish. Rustoleum doesn't
dry very hard over dope. This boomerang has been my favorite flyer of late.
In light wind, I can get 20 seconds out of it.. | |
| 19 Oct 2003 - Rustoleum Boomerang Finish |
This clear acylic spray finish seems to do a decent job; dries hard after
24 hours or so. | |
| 19 Oct 2003 - Clearcoat |
The final touch is to do a final light 000 steel wool sanding and then to
apply paste wax. | |
| 19 Oct 2003 - Waxing |
Two "Ted Bailey MTA" Boomerangs. | |
| 19 Oct 2003 - The Outcome |
Now that I've caught the bug, I'm moving on to even more styles.
Here's a close-up of my 6th boomerang, a "Lazy Seven". My attention to
detail has improved and the latest booms are veeeerrrryy sensual to touch. | |

Here's a detail shot of my 7th boomerang, a "Simple Bois" - pre-finish.
This design, unlike most classic boomerangs, does not have a flat bottom.
Instead there is an undercut at both the leading and trailing edges - apparently
in an attempt to reduce lift in-flight. Since it takes the mastering of about
5 degrees of freedom to get a good flight from a boomerang (elevation, layover angle,
spin, strength, wind), adding more variables (undercuts) to the mix seems dubious. | |

And here's the full collection to-date. Fun, fun, fun.
You're free to go, now. Thanks for looking. | |

Looks beautiful! Just asking, is 5 grams too light for an MTA boomerang? Also, if it's too light, how do I add weights (coins) on it such that it balances well and is able to fly without spinning in an out-of-control fashion?
I just found this! Who knew! Very cool, but your Mom's comments were my favorite. Shows that Wittemore competitiveness and also a pinch of "do that outside!" Lose an eye! Fantastic.
it sees that your photos was all interesting...
Godbless there
hello there, i was searching for some adjectives and it came to my surprise that i found your some photos and i amaze on it..it catches my attention!!!
Hi I found your boomerang photos while searching on Google. Nice work. I run a group on yahoo about boomerangs and would love to have you join and share your building techniques. Already have 10 or 12 David's on the list, but there's room for more. Check us out at:
