Oops! I forgot a mod. Again, it's wood. I couldn't help myself.
Well I just ordered them and I'm hoping I got the right one!!!
I got a link to a video that shows replacing the wire and wick which is about as deep as I want to get into this. They say the heads are so cheap it's not worth the trouble but I want to try it and use cotton as the wick.
I guess I'm getting into the experimental mode!!!
