We are also looking at building a greenhouse - possibly with a shared wall or at least near the forge building.

Has anyone given any thought to the possibility of using waste heat from a solid fuel forge fire for using for something like this? We will be building a rocket mass heater for another project, and it looks to me like running the (or at least some)  of the forge heat through a similar exhaust/heat exchanger should work for the greenhouse.

I am looking at building a small forge on ' skids ' - zoning issues - will probably never move but . . . 

My question is about whether or not insulating it is practical or not.  I live in central Saskatchewan (Canada) and our winters are cold -40 is not unusual,  snow etc. This will be a hobby thing for now, but I'm mostly retired, and who knows? This will likely be used mostly in winter, as my wife and I are gardeners, and have lots to do in the growing season.

The building plans are fluid now, but will probably be in the 10-12' X 16' range, with overhang for outside storage, etc.

I am looking at using a small propane forge, but mostly  charcoal (30 acres to work on, more-or-less free wood, + steel drums. . .)

Any thoughts on insulation, ventilation, ceiling height, etc., would be appreciated.

I am trying to get started into blacksmithing and have been looking for an anvil (or something to use).
We wound up with a job near a local metal recycler, and I checked there several times for something.
They had a BIG bent forklift tine there that I had them cut the straight portion of the back off for me. (no way could I have even moved all of it)
I now have a piece 3" X10" X 27" - about 180 lbs worth - that I got for $40 bucks.
Now I have to figure out how to work it into an anvil.
any suggestions?
