  1. As to the availability, we have to figure out how to produce them reliably and also workout all the other stuff. As soon as possible. Life stuff has this effort slowed for a couple more weeks. I am still conducting burner experiments regularly. Nozzle experiments as well. As to the running a forge with a plastic inducer, there was too much radiant heat for mine. Pointed up helps with chimney and may induce a little more air but it wasn't enough to compete with the radiant heat. The plastic melt point is too low. I suspect you are right about the NARB's doing a little better with this. Mix tube length can get the plastic a bit further away from the forge. The 3/4" burner has a longer mix tube then the 1/2" burners I tried it with. A few extra inches might make a lot of difference here. Though, the mix tubes themselves can get quite warm depending on forge design and they don't have to get very hot to make the plastic soft. User jwmelvin is using plastic reducers with a NARB running at full temperatures. He did have one go soft which he talks about on this post of his thread but he is still using plastic as far as I know. His reducers have an open back(plastic free) so radiant energy may not be hitting the plastic like it does with my inducers. He is another user to ask. He can probably provide you with more information than I did on the subject.
  2. Now you are making me hungry. I loved the red rice and coconut candy. I haven't been back. It was 91 when I left. Utah, 5 hours away. Small world.
  3. That is cool 671jungle. I was a Navy brat. It was one of my favorite places. I lived there a few years when I was a young boy. I wish I was older so I remembered more. I remember only the young boy highlights. The boonies, toads, geckos, hermit crabs, banana spiders, concrete pillboxes, Gab Gab beach, the typhoons, the food, etc. The food. I am made fun of regularly for my still love of spam. My father brings up chicken kelaguen whenever Guam enters the conversation.
  4. No worries. I didn't want you ending up in the dog house over a misunderstanding. Thank you for sharing your information.
  5. The one time I had a moderator warning, I was able to respond to the moderator and it was cleared up easily. I'd be careful about public criticism of regulations/moderators. On the second post of the site guidlines page mentions contacting the owner(Glenn) to discuss matters like this in private.
  6. Wait, so you are saying the cart goes behind the horses. That makes sense, I think I got it now. Cheech, listen to Mikey. Before your burner is dialed in, there is no point playing with the nozzle. Dialing in your burner will most likely change where the flame rides within the nozzle. Then if you still need to, play with nozzles.
  7. Now you are getting to the beginning of my life. My earliest computer memory is playing 688 attack sub on a 286 while living on Guam. I have since played with a Timex Sinclair 1000. Upgradable 16K RAM pack. My favorite was the introduction in the manual, which I kept. Some highlights: You will enjoy computing. You will find it easy as well as enjoyable. You shouldn't be afraid of the computer. You are smarter then it is. So is your parakeet, for that matter. You will make mistakes as you learn. The computer will not laugh at you. Your mistakes will not do any harm to the computer. You can't break it by pushing the wrong button. You are about to take a giant step into the future. Everyone will soon be using computers for every part of their daily lives, and you will have a head start. A computer is a tool, like a hammer or a saw - or perhaps like a food processor. Hammers and saws generally do only one thing well. A food processor can perform different operations, and normally you can "program" it by simply pushing the proper buttons. In the near future, your personal computer will be able to dial and answer your telephone, monitor your burglar alarm, control appliances, water your lawn and perform many other duties for you.
  8. Right. You don't want to use the little scorers for obvious reasons and the power steamers are also out. That does sounds like quite the chore.
  9. No worries, I knew you were kidding. My intent was also humor. Ba dum tss.
  10. I sure looks like the flame is riding deep inside the nozzle. I don't have much experience with threaded fittings as nozzles. You could try a 3/4 coupler to see if it still holds the flame. You said 75% which I am guessing you are talking fuel pressure. What kind of pressure are you running for these pictures? What is the brass fitting in the side port of the inlet tee? That is blocking the air inlet.
  11. The cast nozzle is the way to go. I have completely abandoned metal nozzles. I recommend casting a few in cheapo plaster to find a good size/shape so you don't waste KOL. I prefer to cast the nozzle on it's own and then cast the forge liner to glue the nozzle in place. Printing the form and trying to ram KOL in place in the forge hasn't turned out as well for me.
  12. It will do full animation of the hot end along it's path. It is very handy for narrowing down print problems. We could find a workable solution for your wall paper. I am very much looking forward to this as well. I am also waiting for the different varieties of conductive filaments to get there. It is all very awesome. We have been in the cnc game over here for a number of years but 3D printing is in a realm of it's own. I still remember the joy of emailing a product the first time.
  13. Hopefully you avoid the "slightly used" part but it seems making more then one forge is in the cards for most. You build one and immediately think "next time I will..." and/or you use it for a while and come up with some reason to need/want another. The best advice that I see routinely is avoid the thought "I will build one forge and I will build it big enough that I can make everything I can ever imagine making." This usually ends in a disgustingly large forge which is not hot enough or uses so much fuel that it is very quickly abandoned. Using bricks allows internal volume to be adjustable which is very nice. We recently built a forge which is 185 in³ and it has become my favorite for general use. Now we are planning a forge at 50-75 in³. We also have a 150 in³ and a 450 in³. The 450 only comes out to play when it has to.
  14. Thank you for the reminder Mike. I get ahead of myself and forget my manners from time to time. It is a beautiful blue flame and a hot looking forge. Nice job. One thing I just thought of, if you pull the nozzle back into the fire brick, the firebrick may be heated more which could cause the brick to crack.
  15. A good look at the flame will tell you what you need to know. If you can, get a picture of the flame.
