Hi All;
Planning to convert my J tubes to batch box's this year (I hope).
I bought the correct size square tubing to make a floor channel for my 6" . 1.5 x 1.5 x 1/8" square tubing.
Heading up to Big fork later this week , to buy 50 insulating fire bricks.
Morgan super wool is already here.

I am going to convert my shop stove over as well. It will be an 8" batch box.

Does  anyone know (Peter are you listening ?) What is the size required  for an 8" BB floor channel?
Will the same size as the 6" work ?

I'll be starting work on fabricating this 6" channel soon.
A new post with plenty of photo's at that time.

Yes, I am listening.
And no, you'll need a larger size in order to have it in proportion. Let's see... that would be 1.85" square by 1/8" thickness. One of 1.75" square by 14 ga or 0.083" thickness being the closest according to MetalsDepot. Don't be scared because of the lesser thickness, heavier steel doesn't necessarily last longer.
