Thanks guys for the info and advice. I was looking for a thread like that as I’m a member of a few forums and they all seem to have a similar page but I couldn’t find it. Maybe the admins can put it in the welcome email after signing up. I will read the link tonight. To clarify a bit I did lay down 2” of kaowool and sprayed rigidizer on it before applying the KOL 30. For the most part I have followed instructions on how to build forges the only difference is I used a steel square tube no a propane tank. I’m glad to hear that the bond is not an issue as much as I thought. Thanks again for all your help. I’m sure you’ll be hearing from me in the near future.
