I think creating a sub forum specifically for Rocket Ovens is better for what you want since a single thread for Rocket Ovens DVD would be harder to search and keep things specific to what QA and technical question a member could have. A Rocket Oven subforum would solve that issue.
For now, I suggest a new thread for your technical questions so you can get answers to your specific questions as soon as possible. I know I have a lot of questions too.
agree, there is already one set up for plans, which I believe are being updated, which is great. I notice some techy questions had already been addressed at the other thread, which seemed to have been started to address backer, down load, shipping , upgrades etc, leaving the one that Paul set up specifically for q&a ready for the barrage. Hopefully that is where comments related to the actual build will be posted.
My first question is regarding the back of the oven, and wondering if there is a tight enough seal to prevent exhaust gases from entering the oven with it being held in place by rivets. Has any testing been done and I am guessing a lot depends on the soundness and roundness of the parts being used by any individual, but if one felt, after building it that there may be some leakage, what would be the recommended sealant to use?
