Thanks, I did what you did, fabric a side sucker, with heavy plate, hell to bent, no welding. Installed inside in back of hood. Very impress. Next, a bigger pipe. And it is fascinating to see the smoke going side way...out, and not floating around
Venturi effect isn’t something thats just willy nilly, its a scientific science of inter dimensional portals. Its like your hood is a black hole and your chimney top is a white hole. Getting smoke to teleport properly requires proper measures, prayer and a a few mantras
That was fantastic! I’m building a new forge and plan to use the super sucker concept. I like the traditional hood look, and will likely build something similar to your modified hood solution! It’s good to know the hood “depth” can be extended , as I would like to run the horizontal thru the wall behind the forge, then turn vertical outside the building to avoid the roof penetration completely! Thanks for posting and providing inspiration to proceed on with my “traditional” approach to my period smithy.
Great explanation! I have a wacky setup that shouldn’t work but it does. It starts with an 8” pipe that goes into a 90 degree bend, reduces to 6” double wall pipe, then expands back into another 90 degree 8” pipe. Hard to imagine. The only reason it works is that my coal forge is mostly enclosed reducing the amount of cold ambient air mixing in with the hot. Sort of like the expansion part of your setup.
Really great video as I'm just looking at building a super sucker. Couple of Qs if that's ok. How close to the firepot does it need to be? Just thinking of working space in the fire? And can it be slightly above the level of the fire? Can you tell me the rough dimensions of the sucker box you used? Thanks
Hi Damian, you generally want your super sucker to be in fairly close proximity to the fire you wouldn't want the center of the fire to be more than a foot away from the entrance of the super sucker, and yes, it can be a bit above the level of the fire. As for the box in this video, it's roughly 12"x12"x12" with a 10" pipe flange, the box entrance is roughly 10" sqaure.
It's just 12" duct pipe. Believe it or not, the pipe doesn't get very hot. This is galvenized pipe that's been used for several years and hasn't even got hot enough to mess up the finish.
Hello thank you for your video, would you still need a hood even with the super sucker? also is this good enough (safe) for a 180 square foot workshop?
I appreciate your concern, but all is as well as can be expected. Life is challenging lately, but I've been very busy. Video production takes a lot of time that I can't spare right now. I will be back at it soon.

great vid, I'm learning everyday, this is exactly what I need on my shed, I subbed!!

Awesome video, great work. Thank you sir.
Thanks, I actually have the pieces for that exact super sucker design that I need to get together and installed so running across this was good.
..Good to see you posting again sir...!
Thank you kindly
This is a great explanation, much obliged!
Glad it was helpful!
That's what my local group has in the smithy. I'm working on building one in my shop along with a masonry forge
It's not hard to do, I think I whipped this one up in about an hour.

Very helpful - thanks mate!
You're welcome!
Is there a fan in there or just natural air flow?
That is purely natural airflow. This is what happens when you have a properly drawing flue

What is the stack made of? Thx

Hello thank you for your video, would you still need a hood even with the super sucker? also is this good enough (safe) for a 180 square foot workshop?
You do not need any other hood with a super sucker.
Hoping all is well, or well enough. I'm a bit concerned.

Boy does that suck.
