Thank you for the advice Zapper!
I already did the dry stack method of running rebar through every other hole and filling them with quickcrete. The other holes are filled with dirt. Then the whole top is capped off.
If the thing were larger, I probably would have used mortar.
Then I followed bubba's instructions and did two thin layers of mortar on the outside of the base. It turned out pretty well....especially for my first time. lol I have not painted it or anything, it's just plain mortar right now.
I have treated the outside of the wood with a clear, weather sealer....heck, I can't think of what it's called right now.
I had one firebox made out of 20" pipe, but the lid was so heavy, I couldn't even get it opened.
Now I have one made out of 1/4 of a barrel.........It should be easier for me to handle.
I'm still in the middle of attaching the firebox and pipe to the base......I put a baffle/valve in the pipe for more smoke control.
The last 3 weeks have been too busy for me to get anything accomplished on it.
I had planned on having it up and running by November.........huh... so much for that plan!
I sure do appreciate your input......now that I know you work construction, I'll be bugging both you and bubba for advice on my projects.
