CreekSideForge Posted August 14, 2017 Author Share Posted August 14, 2017 Yeah I know. Probably going to do that for the next rebuild in the future. I just left the hood because its there and its kinda breezy where I'm at so it helps as a wind block too. I might put adjustable side shields on it to reduce the ambient air flow.

Charles R. Stevens Posted August 14, 2017 Share Posted August 14, 2017 Upping the size of the flue and getting it above the ridge line won't hurt either. But side drafts do tend to scavenge beter than hoods. Quote Link to comment Share on other sites More sharing options...
Frosty Posted August 14, 2017 Share Posted August 14, 2017 Hoods that large don't get enough waste heat from a forge fire to draw well, they have to depend on open air convection for a flow. I have a larger over head hood on the BIG coal forge I built before I discovered I didn't know where the good coal was. and it didn't work worth poo even with a over large fire. Worked a treat if I built a wood fire even without the blower. As a temporary patch you could make a small side draft from a piece of 10" stove pipe by cutting away a section of one side. Then simply slip the crimped end up into the pipe on the hood you have. Trim the length so it fits between the existing stack in the hood and the table of course. Don't worry about it fitting exactly reasonable size gaps at either end won't effect things. The side draft will get a strong draw off the fire and just shoot it into the stack you have now. It won't be perfect but should be better than relying on an open hood and last till you get something else built. Heck, one of our guys located a seam of good smithing coal and I've got to start thinking of making a coal forge work again myself. Frosty The Lucky.

Charles R. Stevens Posted August 14, 2017 Share Posted August 14, 2017 Jerry, that's the kind of temporary fix that could be dang near permanent... Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted August 14, 2017 Share Posted August 14, 2017 Could you run some pipe down from the juncture of the hood and chimney and have a side sucker made using it? (Sealing the connection to not draw in ambient air of course.) Quote Link to comment Share on other sites More sharing options...
mutant Posted August 14, 2017 Share Posted August 14, 2017 I have a crazier setup. My forge goes from 8" pipe to 6" back to 8". The 6" is a metalbestos pipe which is a insulated double wall pipe. I used this because of a tight fit through my shed opening. Too make matters even crazier, I have two 90 degree bends and a slight bend from the forge. I have no issues with draft or smoke coming into my shed. If you close up your opening so a lot less ambient air mixes with the hot air- it'll draft. I have a video if you're interested.

Charles R. Stevens Posted August 14, 2017 Share Posted August 14, 2017 I think Frosty and Thommas may have the best idea, you maintain the large opening, shade and draft protection (and cool look) of the existing fire place wile gaining the effecency of the side draft. They will acualy suck the flames sideways into the pipe. Quote Link to comment Share on other sites More sharing options...
CreekSideForge Posted August 15, 2017 Author Share Posted August 15, 2017 Do you think that putting a makeshift side draft pipe that's 8" instead of 10" would just as well? I don't think that there's any 10" pipe where I'm at that's not galvanized. And how close to the fire should I place it? Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted August 15, 2017 Share Posted August 15, 2017 I don't understand the galvanized part. My chimney is made from spiral seamed 10" galvanized ductwork. Except for the vent on the end it never gets hot enough to worry about galvanization. And you can build the vent out of plain sheet metal...

CreekSideForge Posted August 15, 2017 Author Share Posted August 15, 2017 My last chimney was galvanized and I didn't have a problem with it besides that it sucked. I'm just worried about the zinc poisoning, I've read that people have gotten really sick or died from it. I'm just going the "better safe than sorry" route this time. Anyways, It works great right now, far better than my other forge. I forged out the bigger piece yesterday and then heat treated the other before I shut it down.

ThomasPowers Posted August 15, 2017 Share Posted August 15, 2017 I gave the parting toast for Paw Paw Wilson at Quad-State the year he died from complications of Metal Fume Fever and so I've very aware of the issue. I have never had any problem with it in my forges. Look at the super sucker designs and you will see they put the galvanized pipe far enough away from the heat that it doesn't have problems. YMMV Quote Link to comment Share on other sites More sharing options...
CreekSideForge Posted August 15, 2017 Author Share Posted August 15, 2017 My condolences to your loss. I will definitely look at the super sucker designs and add on some kind of side draft. Thank you for all of the help and suggestions. Quote Link to comment Share on other sites More sharing options...

Charles R. Stevens Posted August 15, 2017 Share Posted August 15, 2017 Look at the seam on 5" black stove pipe, it pops open and two 5' pipes zipped together make 10" pipe. But as the rest of the system is 8" 8" might work Quote Link to comment Share on other sites More sharing options...

CreekSideForge Posted September 4, 2017 Author Share Posted September 4, 2017 Its been awhile because college started, but I did the pipe under the hood thing and it worked great. Definitely permanent. Thank you all for helping. VID_20170902_121948.mp4 Quote Link to comment Share on other sites More sharing options...
