I agree Tom fiberwool is nice to work with. Did some work with it at the Kidd Creek zinc smelter. We used to use it to plug refractory cracks in the heat recovery boilers. I plan to use it in a forge I would like to build (to many projects to little time). The brick was free so it reduced my costs considerably and it is of high quality. Don't know if I mentioned it before but 30 some odd years ago I built Gingery's Lil-Bertha and did some casting. In the first pic. from left is a sander table I cast some obvious beginner problems but it held up longer than the sander. An unused steel crucible still kicking around, some moulding stuff, a set of screw drivers I cast, not recomended for electrical work but indestructable in the shop, plan on casting some more. The black handled srewdriver is like the one I used for a pattern. And on the end a mold rammer still kicking around. The next 2 pic.'s are a couple conveniences I added to the frame today a peg to hang my burner wrenches and lighting wand and hooks to store propane and oil hose. The next 3 pic.'s are the second heat today. Got to less than 1/4 on the fan damper before the crucible reached orange heat. Backed off and held for another 5 minutes before shutting down. I don't think having enough air to burn oil is going to be a problem. :D Sorry about that last pic. trying to focus on the crucible. Cheers CB |

Expected a slow day watching fire in the furnace, not going to happen. Decided to try the atmospheric burner in the morning heat. It lit but insisted on burning well down the pipe. No adjustments I made would get it out of the pipe. Tried it on the vise, good there. Removed Asian welded burner pipe and filed down the weld ridge down the middle of the pipe, tried in furnace, no go :bang:.Because of furnace back pressure the venturi effect of the reducer was not generating enough velocity to overcome the flame advance. My jet was 3/4" from pipe inlet, Rupert Wenig's was 5/8" but some of R. Reil's were as much as the full length of the reducer 1 3/4" :coffee:. I removed the T and jet and went with a straight pipe with a #53 jet drilled in it. After some fiddling to center it down the burner pipe, distance to burner pipe now 1 1/4". Lit on first try and did not retreat into the pipe as I ramped it up. :D Installed 2 grease fittings on the main lift slides. The rest of the pictures are my evening heat with the atmospheric burner. Moisture is all gone, developed a few small cracks. If or as they get worse an occasional application of vesuvious should keep it in repair. Included the second last pic. just for the rich color. This was just before I shut it down. Cheers CB |

CB - I can't contribute anything but if there's a new instalment when I log in it its the first thread I open to read the next thrilling instalment. Thanks for taking us along .... :beer: Dave (IOM) |

I'd just like to point out that you will almost inevitably have cracking, it's the nature of the beast, a rigid material heated unevenly is probably going to crack, hopefully fine hairline cracks! i wouldn't worry about it! Regards, Matthew. |

Thanks for the kind words Dave. I'm doing what I enjoy and get to share it with like minded people. Can it get any better? :) cheers :beer: Yes Matthew have to look close to find few hairlines in hotface. More obvious in fireclay mix in lid. The support installed in the lid should hold things together and the occasional morter application will hopefully prevent any crumbling. Cheers CB |
