Some people have suggested unbending the tabs and drilling them for pins so it could be disassembled.
In theory it would work, although you'd have to make it a very tight fitting. The tabs are on the bottom of the short sides and hold the whole structure together. The long sides come out by sliding, so as long as the tabs remain in tightly the stove cannot come apart.
I suppose you could also unbend them each time you disassembled it, although metal fatigue would mean the tabs would eventually snap off.
Bending permanently seemed the best way to ensure the tabs do not come out, but I'm certainly open to the idea that it is not the only way to achieve this.
Obviously I cannot guarantee the stove if people want to mod it though. As I sell them I know 100% that they work.
My prototypes were hand cut from sheet metal using a dremel - it took a loooooong time
Perhaps this is not the correct place to discuss Mods....
Why would I object to free bumps for my advertisment?
In any case, inventors love being given the opportunity to sing their creation's praise.
However as I said, I'm limited in my ability to implement any changes right now, although I'll certainly file them in the "maybe" drawer in the event I ever do another production run. So thank you for the input.
