We have some aluminum on hand that is the perfect thickness to make a Bat Symbol out of. I modified this design by Abir Alward of the noun project. And all I had to do was cut it out! Easy peasy. My next step is to embed it in a block of wood and create a clock out of it, using this mechanism. I'll likely have the wood block cut soon, but the clock I will need to wait on to arrive.
Oh and it's polished it using the lathe polisher. Need to sand it down better next time to get more shiny, but it does pop quite nicely and reflect the light beautifully!
