I personally haven't had any noticeable problem with paper concrete forms, but I can understand the apprehension. What I don't like about the forms is end cap mounting. Also, if it falls it's easily damaged (like when your wife opens the garage door and the back of the door hits the top of the coil! Yes, I know, my fault).

I'm not so sure if using paper concrete forms is such a bad idea if you take care to make a careful selection and remove the "inked" layer, properly dry and varnish the form. For example, here is a picture of a 12" by 48" coil built by Dr. Spark producing about a 8 foot spark. This coil uses a cement form and has produced arcs in excess or 14 feet with no problem! http://www.drspark.org/images/wwt2007/1281.JPG Spark on! Woo
