playing around

It is Sunday afternoon, the temperature is hanging around 37 degrees and it is raining off and on. Not exactly the weather I want to be making boomerangs in. Wish I could do something. Wait a minute, didn’t Chris send me some black plastic deli tray bottoms? Where did they go? Hmmm, check the storage shed, they must be there. Found them, let’s get back in the house where it is warm.

Ok, back in the house and at the computer on Pierre Kutek’s site looking at plans. Here’s an interesting one, a triblade called Triple 6. On the same plan is the Forty Four, a quad that looks promising. I also find the Floatsy, another quad design I like the look of. I print and head to the kitchen where the stack of plastic waits.

For the first shapes I tape the plan to the plastic and cut them out with a kitchen scissors. This stuff cuts sort of easy, except for the edges where the tray is not flat but has ridges. Fortunately this area is not on the boomerang itself. I cut out one of each shape and quickly bend in an airfoil. The I slip outside into the cold for a test throw. The Triple 6 is a winner! Nice range for a backyarder and a fairly low flight, I like this one alot. Next is the Floatsy and I have figured out what it is named so. It makes a very short flight, rather hight and floats in. I tweak the airfoils and tuning to increase the range. Its not one of the longest backyarders I have ever seen but has loads of hover. The Forty Four turnes out to be an excellent quad.

Back in the house I use the three to trace out additional copies and cut them out. I am not bending in airfoils yet but will wait and maybe try more or less bend. I might even try some with just positive diheadral. These will be fun to play with. Here’s a close up of the bent airfoils.

Well, I seem to have succeded in having some fun with boomerang building on a cold, wet Sunday afternoon in January. Thank you Chris for the material. It was fun.
