Just a quick word of intro. I just inherited a complete blacksmith shop. My father was a hobby smithy for about 40 years. Over the years I have played around with his stuff from time to time but never really spent much time learning it. Anyways, now I'm setting up the shop and learning what I can. Still have not fired up the forge as I don't have a chimney yet. I've been reading books and poking around on the web. I have a decent mechanical aptitude, having done a lot of woodworking, some plumbing, and some electrical work over the years. I am a professional pilot by trade, so I have a good understanding of how high speed aluminum tubing moves. Live in rural (yes there are some rural parts) New Jersey and my shop will be unheated but well protected from the elements. I also inherited oxy-acetylene tanks and an arc welder. Don't know much about either of those things, but I'm looking for a local welding class to take.

Another thing that has just crossed my mind... Designs say that the opening should be nominally smaller than the opening of the flue pipe. Designs also say that the super-sucker is 13" x 13". That equals 169 square inches of area. A 10" pipe has an area of 78.5 square inches, and a 12" pipe has an area of 113 square inches. Does the (smaller opening) advice refer to the opening at the smoke shelf? Does the smoke shelf actually restrict the opening or does it just direct the smoke? TIA

Glenn and Harley, Thanks very much. I've searched the site and searched the web and have not been able to find anything like a "blueprint" for the Hofi. The two images that Glenn attached are very helpful and they look like exactly what I would like to build. I think that those images and the plans for the super-sucker, can be used in conjunction to build it, but I would love to see actual plans - if anybody knows where to find them. I've also read the full page at http://www.beautifuliron.com/chimneys.htm. That's full of good advice. All warnings about sparks - heeded. Thanks. I do have stone walls and concrete floors, but will purchase a good fire extinguisher before my first fire. Roger

Newbie here. I just inherited an entire blacksmith shop and I'm about to set up the chimney. The shop is in an old horse stall in my barn. The chimney will be stovepipe that will enter through a cinder block wall. I'm thinking about building the super sucker side draft that I've seen plans for. So, here's my question: Rather than have the stovepipe go out the top of the super sucker side draft (SSSD), I am thinking of having it come out the back of the SSSD. From there it would go straight out through the wall and then take a 90 degree turn up. Comments? Suggestions? Advice? Thanks, Roger
