Beginners Take Apart

Hi Chris, Thanks for the weight/density/volume/ moisture content explanation. One of those leftover things from childhood-softwood ain’t no good for a fire-burns too fast.lol. I think MEN did a test burn on a bank of stoves with wet/ dry wood, etc looking for creosote, etc. Can’t recall the results, but I’ll leaf through and find it.

reduction hole.
