  1. Welcome aboard , Les. It sounds like you have done your reading and are well on your way. It will be a cool feeling the first time you get to light up your grandfather’s forge for sure! If you have the time you should start planning out some first projects with drawings. The visualizing is a great start. Managing to get the steel to do what you want it to is another thing entirely:) Lou
  2. Agreed with all of the above. As you learn the nuances of the anvil’s edges you will find a use for them. Down the road you can make a hardy tool with clean edges of different radii for cleaner work if you have no clean edges of the anvil. Welding it without serious knowledge and skill will minimally soften the top and could cause cracking and delamination of your working surface. It’s a nice anvil Lou
  3. Lol. I promise to not change variables until the current test is complete. I certainly could test with higher psi and see how much it takes to run smoothly. At some point, though, I will be pushing as much heat out of the forge as I am keeping in. Once I get a number on the right psi I want to change another variable on oredrr to see what allows me to run more efficiently. My goal is to learn what makes these burners tick as much as it is to make this one work.
  4. The forge is 5.75 inches in diameter. All told, including the 3x3 column at the back entrance, the forge is about 290 cubic inches. I was concerned that back pressure might become an issue. Ive considered more variables I could test in order to deal with the pressure. Changing the length of the mixing tube is one option. Changing the mig tip is another. I figure that, once I play with the ports on the burner block, I will test each of those as well. Any other ideas?
  5. It’s better than most new drills. That is a serious score.
  6. This was great to see! I just saw a guy post an Instructable wherein he made this same design using just Rutland furnace cement and labeled it something like “The Ultimate Forge Build”. I followed him to his YouTube video and tried to give him the basics...but mostly told him he should come here to learn from the real pros. Still, his bad information is now widely available, detailed, and comes across like the gospel. Your approach was thoughtful and your questions were perfect. You were made for IFI! You are nearly curmudgeon proof. Cant wait to see it up and running. Lou
  7. This entire conversation has made me hungry and inspired me to go out to my neighbor’s new restaurant as I haven’t been there yet. He told me that he put khao soi on the menu. Khao soi (Thai coconut soup) with a heap of chili seeds in oil is my jam!
  8. Vincent, thanks for that research help. I believe it supports an explanation for everything we have been working out in this thread. You have a good no weld option that someone on here has already used. Search online for a “T-type threaded conduit body 3/4”. That’s what I’m thinking of using for my next burner. Back to my testing. All, strange results! I blocked off one jet on the burner and more than doubled my run time of 4:20 at 5 psi to 9:35 at 5 psi before blowout. I then blocked a second hole and ran it again. This time it blew out at 7:20 at 5 psi. When it cools I’m going to try it with three holes blocked just to look for a pattern. After that I guess I will run the same series at 7.5 psi. So far I see no logic.
  9. My neighbor is a Thai owner/chef who moved from his 20 year and going restaurant in South Pasadena to try to bring his style to the East. Our neighborhood cookouts improved dramatically since this past summer. Back to my purpose.... my mechanic has been cleaning his shop (two 30 yard dumpsters so far) because he is selling his shop to another family of mechanics. He stopped by my house to deliver me some new old stock leaf springs! Somehow the photo is dark but you can see them still with the tag still on them.
  10. I love the Attwood duo of hammer and anvil. You were fated to have that anvil find you. I love the anvil.
  11. Yup, I followed the plan as closely as possible. I have 19 holes made with crayons. I’m thinking that the severity of my problem may be related to the forge design itself as well. Where I cast the back wall of the forge it bumps out into the chamber just enough to create a shelf that overlaps the edge of the burner. It may created a little hot pocket of air that increases back pressure. By blocking off the jet that is closest to that side, I’m hoping to reduce the effect. I’ll find out today. I hope that makes sense.
  12. This seriously worth the experimentation. I only had the time to run one test today and, at 5 psi, it backfired at 4:20. I’ve decided to not bother with testing at higher pressures and, instead, to block off ports incrementally to see if I can increase that time. Currently the blue flames appear to start inside the ports. I’m going to see if I can’t increase the airflow until they stand just proud of the holes. I’m thinking this will be a good place to start.
  13. Sections of the block do get red hot relatively soon into a burn. I’ll try to get footage of that as I’m doing some of the testing today. I’m thinking about running it at 5,7, and then 10 psi and timing it for blowout. Depending on how that goes I’ll think about blocking one of the ports on the burner block and running the same tests again.
  14. The knife is, as always, a work of art. The story is the blade version of the ugly duckling. It was beautiful the entire time....it is perceptions that change.
  15. I’ll eliminate all but one variable and run tests. I get it completely, Frosty. I have a mind for science! Dan, the smoke/steam is (I believe) from the moldable refractory I used to build out the pocket for the burner. It could be a cause of a problem, but I don’t believe so. I’ll consider it a constant in my tests for now and follow Frosty’s advice by timing at different psi settings. To be honest, I’m glad to be working through this problem. If it went smoothly I wouldn’t have learned nearly as much and, by virtue of my posting here, others wouldn’t benefit. I’m looking forward to the feedback from my next steps. Edited to add: Frosty, as an aside, I changed the pressure because I was trying to induce the desired blowout just to get footage of it for your viewing pleasure. I’m not even certain if my particular blowout issue is a common “type” of blowout. Still, your advice to eliminate variables is well taken. You have my sincere thanks, Lou
