Default Fabricating a sauna wood burning stove

in rec.crafts.metalworking the following:


About the inside of the oven - are any liners (bricks) etc used - or
fire burn right on the exposed metal ?


At a minimum, I would suggest a grate to hold the wood up off the
floor. Of course, after the first fire, you will have the ashes to
serve as insulation/protection of the bottom of the firebox.

A firebrick or fireclay lining will protect the steel from corrosion
and, to some extent, warping. But it'll also increase the time it
takes for the outside of the stove to warm up. Depending on the
design, I probably wouldn't line a sauna stove.


Put the brick on the bottom - that will protect the bottom from
fire. Iron does oxidize. Lining the sides with firebrick will serve
as thermal mass to moderate the extremes of hot/cold as the fire
flares up and burns down. It may take a while to heat the sauna to
proper temps, but it will also take longer for it to cool off, so you
do not have to jump up and stoke the fire.

Steel is cheap and a heavy steel stove is less likely to warp.


That too. There is the issue of over building - heavier steel
will mean that it will be longer till you have to repair or replace.


I don't have experience with sauna specific wood stoves, but did
work for a while making "regular" wood burning stoves for heating. I
think we used a 3/8 plate for the box (it was about "that thick" -
holding fingers about a quarter inch apart).

It's eight fifty eight. Close enough!
