Third Session July 21, more testing and shaping

Today I met Ian at the field and we went right into testing the boomeangs from last week. We decided the Aussie booms were fine, but had to work on the otheres. Back to the shop where I added some undercut to all the wings on the five blader. I also took a little more off the trailing edge. To the batrangs I added some undercut to the dingle arm only. We also sanded a musical note rang and took that along.

Well, the five blader was good enough that I caught it on my finger. Ian also had a catch so we figured those were in the bag as-is. The batarang was better but still not close enough. The musical note flew and tried to return but was too far away. Ian's lightning bolt flew, but had short rang and lost spin quickly. Back to the shop for more work. We added a bit more undercut to the batarangs. I attempted to flip the other lightning bolt blank over and sand it reverse of the first. Unfortunately my brain shut down and before I could think again, had made a left hand rang. Ian decide to sand anothe five blader and had a lefty attack too. We gave up and went to the field for anther test round.

Third time to the field we were getting good returns from the batarangs, so good that the incomng boomerangs scared us. I am not catching them! I still wasn't happy with the musical note so took it home again. Once there we traced  out a replacement 5 blader and a couple more batarangs. Ian got more experience on the bandsaw. He also used the drill press to drill holes for blinkies in one of the batarangs. His favorite tool was a palm sander, and he did all the finish sanding. Ian took the batarangs, five bladers and aussies home to start painting.

    David Ian finish sanded the boomerang for the LD prize table so another person got involved. The Lightning Bolt has small wing tips so Ian is going to ty a redesign. He did well to get it to work at all! We had great fun today. He has 8 or 9 boomerangs to paint so we are moving forward Dave

    I'll try a few different versions of the Lightening Bolt boomerang. I think I will try to do a sketch of a tri-blade and another quader. I think over all I need to increase the width of the blades, especially near the bottom. I hope to get it working, as it looked awesome in the air.

    Did you post a picture of the lightning bolt? Simple shapes usually perform better, but cool shapes are so much fun to see. It's really great when one looks interesting AND returns well. Thanks for sharing.
