The other day I came across a thread I found useful but I didn't subscribe. I've been looking for it for days now. Some one posted a picture tutorial on how to build an atty/cart. It looked super simple, and the designer used an 18g clipped needle on the base, and wrapped their own coils. Whoever it was had some pretty good pictures. Does anyone know what I'm talking about? I'm probably being too vague, but maybe someone can help.
