  1. Good Morning everyone, some better news to report today. Since the latest KOL application had cured for 24 hours I moved the forge outside and installed the burners to start the drying process. I would light it up for a few seconds, then shut it off and let it sit for a few minutes while I was working on other stuff. Wash rinse repeat. Kept a fairly consistent wisp of steam coming out of the forge and the KOL was noticeably changing. Light taps with a small wrench where it was dry would produce more of a ring vs the thunk the still wet KOL made. I even put one of the pieces of crumbled fl
  2. I will give that method a go, inswool is all rigidized, though again this is my first time at any of this so who's to say how well it was done. Learning a lot of lessons to help the next one go much better. I just found Wayne's method where he cuts the tank in half and hinges one side. Seems like a good method to help speed things up as you can cast both sides simultaneously. Oh well you live and learn and try to learn from others but sometimes I gotta get my hands dirty and see how things work out.
  3. Also thank you all for the encouragement and advise. I'm still hopeful that the end result will be worth all this effort. Since a few have asked on details here is exactly the steps I've been using. 1: forge shell lined with rigidized inswool is on it's side 2: pour 5lb bag of KOL into plastic tub 3: weigh out 13.75 oz into cup on postal scale 4: weight out additional 1.2 oz in separate cup for use if needed 5: start mixing slowly adding water until I can form a ball and toss it up and down, usually ending up using all water measure out. 6: get on ground with
  4. New day and a fresh outlook. Still frustrated, but ready to deal with this rather than being inclined to toss it in the bin. (No, I could not have thrown it out, too much time and effort put into it, but I can daydream!) Mikey, are you saying to cure AND fire each section of refractory before turning and going to the next? I only let it cure for a day and didn't fire it. Perhaps that was part of the issue, the KOL had hardened it seemed but when the floor fell it pretty much crumbled. It came off in big chunks but it was very easy to break apart. Swede, I like that idea, however I do
  5. I’ve about had it with this stuff. Thought it was all going well when the entire floor fell down in chunks after I had the forge upside down for a few minutes of putting this stuff onto the ceiling. I can’t even get this stuff to stick to itself hardly. Still the only surface it sticks to is my hand. I had to toss the rest of the mix I had prepped because there were no more horizontal surfaces to put it on. At this point I think I would have been better off just buying a premade forge. Less headache and less money. Now to order more kast o lite since I lost a whole bag of it in the
  6. This is where I am currently at. (see photo) Not very happy with how it is going. I am having a bear getting the dang stuff to stick to anything but my hands... (You can see on the left and right edges it's trying to pull away from the ceramic wool, and in the foreground a small pile of fallen refractory on the floor.) Hopefully once this portion cures it will stay in place enough to rotate and do the other side. Assuming that it is okay to let this cure a few hours/overnight and apply another batch later on? You can see the rectangular rear opening, at some point I will be making
  7. First bag of Kast O Lite 30 is mixed and applied. Started with the 2.75 oz water per pound and ended up adding a bit up to about 2.9 oz per pound after some mixing. I must not have wetted the ceramic wool enough before applying because it isn't wanting to stick too well. 5 LBS covered the floor and up one side about two inches, and a little bit around the openings. Just waiting for the first batch to setup a bit so I can turn the forge and keep going.
  8. Here are a few stills from the video. Must not have been a compatible file format.
  9. Tapered burner ports it is, here is where we are so far. Ceramic wool is all in, rigidized and dried. Attached the two burners and lit it up because I couldn't help myself and we have a fire! I want to make a face to the forge somehow giving the whole thing about a 1" lip to help contain the flame, and then from there use fire bricks on the front and back shelves to block the openings further if needed.

  10. Alright, I think the layout is complete. Pre refractory is 10" dia (with a raised flat floor so 8" height) x 12" OAL (NO TAPER TO THE CHAMBER) factor in refractory and it's 9"x7"x11" which gives me 584 cubic inches. Which means I'll be building another 3/4" burner (or should I build a single 1" burner instead?)
  11. Of course, I even put my dunce cap on! Oh interesting, makes perfect sense though to use the refractory as a sort of Venturi. This sounds really interesting, and to make sure I’m on the same page as you, you’re saying taper the entire length of the forge so the back is narrower than the front opening correct?
  12. I apologize, I don't know why I can't get that terminology out of my head. *castable refractory* *castable refractory* *castable refractory* I don't think I've actually considered burner protrusion much, but I was planning on flush or slightly recessed. Though I do intend to have the burner bolt on so I can adjust that if needed.
  13. Mikey, great question. I'll be shooting for 4 layers on the walls I think, for an 8" diameter with a flattened floor like so in this sketch. Per your recommendation above burner at 2:00 slanted slightly in look good? Though once refractory cement is in I guess that would drop it down to about 7" diameter. Still be plausible with a 9" end diameter and flat floor?
  14. Hey all, just wanted to check back in and let y'all know this is still moving along. It got put on hold again for a little while, but I have some extra ceramic wool on the way now. I'm hoping to have it wrapped up in a few weeks to start working on Christmas presents for the season.
  15. Thank you for the kind words sir. Yes indeed, the owners of the coffee shop are the Steele family. Though not technically customers as I didn’t charge for it, I just wanted a project to work on.
  16. Happy Labor Day fellow smiths. I'm here to show a project I just completed and delivered to its new owners today. Started with getting a copy of their logo and transcribing it to its new scale. The scale I chose gave me 2.5" with font so started cutting pieces to assemble the main part of the logo. 2.5"x0.25" flat mild steel.
  17. Mikey, I think I was inadvertently leaning towards a "D" Forge, or at least "D-ish"... I will read up on those, I found Andy's "D" Forge thread and will read through that. Are there any others that would make for some good reading? After just a few minutes of reading up I'm kinda thinking a hybrid D/oval forge, make it oval with a flat floor. This would in theory smooth the transition to the floor a little bit better as well as reduce some volume by lowering the ceiling of the forge.
  18. Got it, I think our difference comes from me using the 11" as measured with the wool loose in there, which should probably be tightened up a bit to get closer to planned dimensions. I will for sure do a third layer of wool, maybe even on the ends to reduce that volume further. Thanks again for the advise to a rookie, it is appreciated.
  19. Buzzkill, I apologize for not quite understanding. Would you mind typing out your calculations? I gave the over all dimensions of the cylinder I'm using, so if with 2 layers of wool and one 1/2" layer of castable I should be in the ballpark of a 10"Diameter x 9"or10" OAL cylinder I think, which is what I based my calculations on in my previous comment. It's totally possible that I'm off on that so if you don't mind sharing why your calculation is so much different than mine? I am all for frugality, I can't imagine I'll be doing anything larger than the 8"x3" door in the back of it (
  20. Buzzkill, thank you for that clarification. I thought the Kast O Lite was a form of refractory cement. I am indeed using KOL-30 ordered from Glenn. Paul, once I add insulation to the ends and castable refractory to the inside it should end up at 10" diameter x 9" OAL give or take a little bit. So that's about 440"3, add in the floor and I get about 293"3. (figuring the floor to take up approximately 1/3rd of total cylinders volume) Does that sound like a more acceptable volume for a 3/4" burner?
  21. Mikey, Thank you for the feedback! I'd rather here "you did this part wrong" and be able to correct it than to waste time and materials! I'll get some more wool on order to double up the ends, I did not calculate it into my order the first time so what you see in the picture is what I have except a few scraps. Yes refractory cement, NOT regular cement. Just called it cement because I was too lazy to type out refractory every time. My bad. Burner position sounds good easy enough to move still since I haven't drilled anything. Good to know about the floor and Perlite.
  22. I'm building my gas forge with what I could find and that ended up being part of an old water heater, slightly larger diameter than a propane tank forge, and I want to have some more experienced opinions regarding my layout before I cut holes and rigidize and cement everything in. The tank is 16.5" ID x about 14" long (not including shallow dome on one end) I have the end dome with 1 layer of wool, then two layers around the outside leaving me about 11" ID (not counting 1/2" of cement all the way around of course leaving me with 10") I think layering a few extra pieces on the bo
  23. Thank you all for the help! I think a big portion of it was not having a "nozzle". I went ahead and put that on last night and tried it out again and was able to get it running much easier, did some rough tuning and get a nice blue flame with some orange wisps at the end. Much more please with that. Also some photos because everyone likes show and tell.
  24. Don't have any right now but can take photos when I get off work. It's built exactly the same as Frosty's. 1"x3/4" Red Tee, 6" nip, 1/4" nip into the middle of the tee with a .035 mig tip threaded into the 1/4" nip. Nothing on the "nozzle end" of the 6"x3/4" nip, maybe it needs a coupler/thread protector or something?
