Dustin Stephens 1 Posted February 12, 2016 so is a flare beneficial, or can i just roll without? Share this post Link to post Share on other sites
Doug Lester 199 Posted February 12, 2016 The flare will help you not burn off the end of the burner tube if the latter is allowed to extend into the fire chamber. This will cause you to periodically have to rebuild the forge to replace the burner tube. If you keep the burner tube within the insulation and protected with a little refractory it will do the same thing as the stainless steel flair. However, the lining of t he forge will eventually break down, depending on the temperature you run it at, and you still will occasionally need to rebuild the forge. Just not as often.

Dustin Stephens 1 Posted February 23, 2016 (edited) How far down does the mig tip need to be past the air intake hole? And will fire place door fire rope work to seal the hole around the bruner tube? Edited February 23, 2016 by Dustin Stephens Share this post Link to post Share on other sites

Jerrod Miller 313 Posted February 25, 2016 Experiment on tip placement. See what works best in your forge. Start with zero, and then bump it about half an inch further. I bet you won't notice a big difference. And you can seal the tube with spare Kaowool, or any refractory. Share this post Link to post Share on other sites
Dustin Stephens 1 Posted February 25, 2016 refractory cement like derby 3000, will that work? Share this post Link to post Share on other sites
Jerrod Miller 313 Posted February 26, 2016 I'm not familiar with that one, but keep in mind you're just trying to plug a hole with something that won't burn. Some people don't even plug that hole. I welded a pipe coupler to my forge body and formed my flare with refractory on the inside. The burner tube just screws in to my forge. Share this post Link to post Share on other sites
C.Anderson 13 Posted February 27, 2016 I just tapped the forge body with the threads on the burner tube, and screw it directly into the body. I formed the flare into the kaowool with satanite. Done deal, works great. Share this post Link to post Share on other sites
Dustin Stephens 1 Posted March 14, 2016 (edited) Here some pics, just set it in top of the forge. Critiques, thoughts, does it look right? Oh it's set at 5 psi and an .30 tip Edited March 14, 2016 by Dustin Stephens Share this post Link to post Share on other sites
Dustin Stephens 1 Posted March 15, 2016 Hey guys, have a look at my flame, does it look correct? Share this post Link to post Share on other sites
Jerrod Miller 313 Posted March 15, 2016 You'll probably want to adjust your inlet to be at the top of the forge, and angled to get a swirling action with the flame. As it is now when you lay steel in the forge it will have the flame hitting it directly. Also, any pipe sticking into the forge is going to get quite hot and eventually be eaten away. Does the forge get hot enough? Share this post Link to post Share on other sites
Dustin Stephens 1 Posted March 15, 2016 Hey Jerrod, I just held it in there by hand to see how it would act, because it acts differently out of the forge. My plan is to weld a piece of pipe at an angle and mount it in the center angled to one side or the other, I know the tip needs to be in the brick, I was just testing it to see how it looked and to see what you guys thought about how the flame looked. This is the first gasser for me so Im a ball in high weeds Share this post Link to post Share on other sites
Jerrod Miller 313 Posted March 16, 2016 The difference inside and out of the forge is from back-pressure, so when you are testing make sure you have your forge as closed up (doors and such) as it will be when in actual use. Share this post Link to post Share on other sites
Dustin Stephens 1 Posted March 17, 2016 (edited) Hey Jerrod, I was thinking about lining the top and bottom of the inside of my soft brick with hard brick that is on clearance at rural king. Do you think that would help insulate it more, or hurt it? I want to do the top too because that will give more of a surface area for the burner tube to be in brick?? I know i want a hard bottom for sure because i want to forge weld in it and I know the borax will eat the soft brick, but do I need to mortar the seams, if so what do you recommend? IM SO CLOSE to running this thing Edited March 17, 2016 by Dustin Stephens Share this post Link to post Share on other sites
Jerrod Miller 313 Posted March 18, 2016 Hard brick doesn't insulate as well as soft, but it is much more rugged and flux resistant. Hard bricks will also retain heat. So while it will take longer to come up to temp, your forge will run pretty well once it is up to temp (all things being equal). From what others have done with brick forges, it sounds like you'll really want to get some replaceable tiles (thin hard brick) to go on the floor. Don't mortar those in place, but if you want to mortar everything else that is fine/good. Share this post Link to post Share on other sites
Dustin Stephens 1 Posted March 18, 2016 thanks for the help Jerrod, I think im almost there! Couldnt have done it with out you! Share this post Link to post Share on other sites
