Masonry bell on top of cast iron stove? Possible?

I got myself an inexpensive used stove to heat a small space. I'm thinking about constructing a single chamber bell on top of the stove (where there is a 6in outlet). I searched but haven't seen this done (possibly for good reason?)

Initial thought is to construct it of brick. A brick rectangle atop the stove with some kind of manifold back to 6in pipe

Thoughts on this? Ideas for a suitable manifold from brick to metal?

Dan Woloz :I'm giving you a link to our sister site Richsoil.com and a whole series of videos, 3rd from the bottom is an adaptation to a regular wood stove to promote

more heat distribution of the wood stoves heat,, note that this does not burn as cleanly ! Link:

You can also take a look at the work done by Kiko Denser with a masonry Hat onto a small box wood stove !Link here:

The problem with what you want to do is the wood stove will not burn clean enough and your bell is where the unburned hydrocarbons like Wood tars and Creosote are
most likely to settle out onto the interior wall of the bell ! You may have better (or Worse) with the masonry hats !

For the good of the craft ! Big AL
