A TS made of caribou antler! Wow! Exceptional I'm sure you know that the oldest TS was excavated from a cave in Poland, is dated to 20.000 BP, and made of mammoth ivory. Almost every material can be used for making servicable TSs, I guess. As a part of the continuing research about Yenikapı prehistoric TS, I completed three copies (using 3-D computer modelling) from three different materials (and of course three different specific weight). A detailed experimentation will give a clue about the relationship of wing surface and the total mass. About the glue: Yes, I used tapes to reinforce the glued pieces on my snake-shaped stick (glued with epoxy). It Works fine so far. The bat-shaped stick was repaired with carpenter's glue and failed at the first throw, re-glued with cyanoacrylate, but not thrown yet. I know that epoxy works well, so it made sense to me to try another glue. I'll let you know about the results and will make a video to Show the flight characteristics of snake- and bat- TSs. Here I attach a video of a returning boomerang I made and decorated. There is a pic of the bat-TS as well. Hope you'll enjoy.

I love this forum.

We have guys from Turkey, the US and France talking about making throwing sticks and boomerangs.

What is interesting about the piece of antler was that it was just the main beam, the rest had been cut off to make tools for flint knapping or into jewelry.  It had the perfect natural curve, all I had to do was split it length wise. 

That's a neat three bladed boomerang.  The first one you made just worked perfectly?  That is when skill and a little luck came together perfectly.
