well I finally got around to turning the coke machine i got last spring into a incubator I will post pics in a little bit, I still got to take them. I do have a question will the foil tape hurt going over the flexwatt at all ?? I had to tape across the watt to hold it in place while I taped the edges down. the stuff like tinfoil in feel and not very thick. ( electircal tape is heavier) ?? I can remove the tape from accross it just takea a lot of time this stuff works great ( Might try to see if it works on wood as well as it does on the coke machine .. )
