ArtMetal

I am new to the Art of Steel. I am an Airbrush artist, and woodworker. I have recently taken a few classes in Artistic Welding. I would like to bring Wood, Airbrushing, and Steel to life.
I want to try something I think I can handle. I want to make some Steel candle holders. However, I can't find a place that sells the Candle holder base. The one that has a single spike in the center to hold a large candle. Can someone tell me where I can find it.
Thank you.
