I started out with the classic Gemini symbol.
This almost looks like a double ended slingshot already! So I formed my plan - adapting my HammerHead design to the Gemini theme.
For that, I decided to use two different types of wood, each one representing one of the twin pillars of the symbol. I went for Red Cedar (smells great!) and Bubinga.
It was a very complicated build as Cedar is very soft, and Bubinga is quite hard. Not easy to shape these wood types in an even fashion.
This actually has advantages, as you can attach two bands at a time - you have a spare bandset with zero attachment time. It serves as a lanyard in the meantime. You can also attach a weaker target band and a stronger hunting band.
Here, you can see it next to some of the other HammerHeads I own. They look alike, but aren't the same... I vary, in order to enhance the concept further.
This frame isn't competing, in fact it is a prize that will go to the winner of the Gemini contest. Good luck!
