I'm trying to make my wood stove for efficient. I bought stainless steel for this project. I need advice on how to proceed with this,do i weld the reburn bars Or weld in flanges to set them into?what size holes do I drill into the bar for Reburn to take place? Do I need more than one row of holes or more. 1/4" plate for top with 2"x2" tubing for sides, tubes in between tubing. any advice on this would be greatly appreciated.
