Howling dog forge Posted January 21, 2018 Share Posted January 21, 2018 Would you be referring to the Zirconium silicate Bentonite mixture for the top coat?? I have a couple of questions on that too. When mixing is it mixed dry ? is it powdered Bentonite or hydrated "kitty litter"? is the hydrated mixture vibrated or put in a vacuum to remove air?

Mikey98118 Posted January 21, 2018 Author Share Posted January 21, 2018 Yes, that is what I am speaking of. All of your questions are answered in that discussion; go back enough pages to read it all, including the references to the original article in Digitalfire that it came from.

Mikey98118 Posted January 23, 2018 Author Share Posted January 23, 2018 Drilling holes and cutting capillary tubes can both cause internal burrs and scratches to interfere with the smooth bore needed to produce a long volume of gas from gas jets. The answer to this problem is the use of a set of torch tip cleaners to remove them. Link to comment Share on other sites More sharing options...
kander54 Posted January 27, 2018 Share Posted January 27, 2018 I am curious if I could use a flu set mortar as the coating over the ceramic fiber (after rigidizer) or would this be similar to using a refractory cement, I have a local block company that sells "ALSEY Flue-Set" Non-Water Soluble Refractory Mortar-- Medium Duty, which has a service temp of 2700. I am attaching the product data sheet, after this I would apply either the ceramic coating Flue-set_NWS_mortar.pdf Link to comment Share on other sites More sharing options...

Irondragon Forge ClayWorks Posted January 28, 2018 Share Posted January 28, 2018 ^^^This^^^ Mortar is used to stick bricks together, not coat anything. Too thick and it cracks & falls apart. Link to comment Share on other sites More sharing options...
Mikey98118 Posted January 30, 2018 Author Share Posted January 30, 2018 Why do people keep coming up with the" bright idea" of replacing castable refractory with refractory cement (AKA flue mortar, furnace cement, etc.)? I believe it is because it can be easily and cheaply be bought at local hardware stores, and online with minor shipping charges. The desire to come up with an easy answer to their perceived problems overrules our repeated warnings that it doesn't produce an answer; only a mess. The comically sad fact of the matter is that Wayne, a member in good standing here, can supply real refractory in small amounts and reasonable prices. So the substitution is not only unworkable but totally unneeded. Link to comment Share on other sites More sharing options...
Frosty Posted January 30, 2018 Share Posted January 30, 2018 In spite of how many times we've said mortar, cement, etc. make crummy forge liners just illustrates nobody even reads the stickies let alone do any research. Frosty The Lucky. Link to comment Share on other sites More sharing options...
SLAG Posted January 30, 2018 Share Posted January 30, 2018 Frosty, Well said. Masons/bricklayers use mortar and NOT cement to set bricks. Cement is too strong a bond. If the construction is made of cement and brick the brick will crack in half, due to too much stress and not the cement. Mortar is compounded for that specific requirement. It is soft. It is not for kiln use. Regards, SLAG. Herr Howl, Your aphorism namely, "If I was the smartest guy in the room, I was in the wrong room" is brilliant. I intend to use it in the future. I should like to give you credit, if it is original? SLAG. Link to comment Share on other sites More sharing options...
Mikey98118 Posted January 31, 2018 Author Share Posted January 31, 2018 3"Bosch angle grinder Here is another choice in 3" angle grinders; it is also overpriced compared to the Chinese imports, but is at least is a manufacturer well known for top quality. One of its advantages is that its motor is in line with the cutting and grinding discs it swings. Thus no power is lost to gearing, and no high-speed gear whine is created either: Mod note: Ebay link removed Link to comment Share on other sites More sharing options...

Howling dog forge Posted February 2, 2018 Share Posted February 2, 2018 Lit one Frosty burner this evening , just clamped in a vice not in anything yet. I have two projects in mind, replace the refractory and replace the 1/2" burners with 3/4" burners and build a a small 300 in³ with one burner. I think the one burner may offer more research and experimentation possibilities than the other. that thing is going to be super adjustable and super simple, that thing rocks. Frosty, I stand on the shoulders of giants,good job mate. Link to comment Share on other sites More sharing options...
Frosty Posted February 2, 2018 Share Posted February 2, 2018 Oh puhleeeze, I have trouble getting my hats on as it is! I didn't do anything but modify an existing burner design and make it as simple as I could for folks without a metal shop. Glad it's working for you. Frosty The Lucky.

I have been overwhelmed by the lack of information and/or the abundance of misinformation on burners and refractory among the smithing brethren. this site and the insight of the people within has changed or realigned a lot of things I had come to consider true. for this I thank you , one and all. In your case Frosty I am happy that someone has done things that will reduce the odds that I will end as a large crater next to my neighbors burning house. In my case I have taken your ideas and made them more complicated, something I am prone to do, but only because I have access to machinery that others may not have. I applaud your effort to make this an option with anyone with any mechanical ability but is equipment challenged. Link to comment Share on other sites More sharing options...
Frosty Posted February 2, 2018 Share Posted February 2, 2018 Indeed, a lack of smoking craters and burning neighborhoods is a goal of mine. It's tough to avoid the more is better thinking, you should see some of the things I tried before KISS fixed it all. There are a lot of folks refining smithing tools and with online fora email lists the info is getting around. Unfortunately Youtube tends to spread ignorant and outright dangerous bull pucky. Happily one of the more egregious examples got himself arrested for making and detonating home made explosive devices. If you see something interesting online how about bouncing it off us before giving it a try yourself. Lots of us have made and had . . . .exciting experiments and devices. No good reason to repeat failures and disasters. Frosty The Lucky. Link to comment Share on other sites More sharing options...
SLAG Posted February 2, 2018 Share Posted February 2, 2018 Frosty, What explosive did the arrested dotard try to make? My curiosity is welling up. SLAG. Link to comment Share on other sites More sharing options...
Frosty Posted February 2, 2018 Share Posted February 2, 2018 I don't have the link to the news article anymore but IIRC the devices were dry ice and water in containers. The news didn't specify chemicals for the other devices, no telling who will give a thing a try. He and a buddy were arrested on felony charges for both: devices and explosive chemicals. I'd speculate the news was being cagey about home brew anfo. It's the kind or thing the King of Randumb is capable of. The article also said the authorities had been watching his videos and were ready to act when a neighbor called in a complaint about explosions. It's been a couple few weeks but someone on IFI linked me to the article. It put a smile on my face, not because he was in trouble but because the world became a little less dangerous . . . for a while anyway. Frosty The Lucky.

Frosty Posted February 3, 2018 Share Posted February 3, 2018 My pleasure Slag. Say, you'd probably know, would misconduct with explosive devices and materials be Federal offenses? Frosty The Lucky. Link to comment Share on other sites More sharing options...
SLAG Posted February 3, 2018 Share Posted February 3, 2018 Frosty, Explosive s and misconduct relating to them are most probably a State criminal matter. (crimes are covered by State law). But criminal activity is also covered by Federal legislation. especially when crimes are carried out across state lines. Country wide activity is often a Federal matter. (inter-state commerce, communications etc). Areas that are reserved to the Federal Government by the U.S.Constitution. Also, included are Federal laws that cover matters such as security terrorism and Homeland Security, etc. etc. Am I being somewhat vague? You bet.. For several reasons. I was never involved in criminal law. (far too many criminals for my "taste"). Two, I almost exclusively practiced intellectual property (I. P.) law. (patents, licensing, trade marks, etc.) And generally before the Federal Court of Canada. (criminal and patent law are federal jurisdiction in the Great White North). Alright, I am not really answering the question. On first guess I think the individual States and the Feds would probably have jurisdiction to act. I can find out. I will give the Federal Attorney's General office a call to inquire. It might be a little fun and will raise a few eyebrows. Regards, to you and all the other good burgers in Seward's Folly SLAG. Could you or another i.f.i. member post a reference to the news item for me for needed details? Thanks. As an added F.Y.I. dry ice does not chemically figure with A.N.F.O. explosives (Ammonium nitrate fuel oil). They would not figure in a significant explosive synthesis. But there are other ones and that's a whole 'nother tale. Link to comment Share on other sites More sharing options...

DavidF Posted February 3, 2018 Share Posted February 3, 2018 Here is the local coverage. https://www.ksl.com/?sid=46238745&nid=148 This guy is about five miles from me. They were detonating dry ice bombs. Pressure builds up from water on dry ice in a closed/sealed container and they are very powerful and extremely dangerous. They also had a bag of unknown chemicals which were harvested from an aerial firework. That is probably more frightening because of the fire hazard. I will see updates when his case moves forward and post updates when they are avaiable. Link to comment Share on other sites More sharing options...

SLAG Posted February 3, 2018 Share Posted February 3, 2018 DavidF, Thank you for the reference. I will follow up on it shortly, get the facts, and commence mischief. This reminds me about reading the Nazi experimental liquid air bombs, in the middle 1930's. They worked splendidly, made a wonderful mess. But, (there's so often a but). The explosives tended to go off at inopportune times. Like in the bomber, delivering the device. They never solved that embarrassing problem, so they went back to the old stand-byes. (t.n.t., r.d.x. etc.), and lost the war. Time to pack it in for the day. Night all. SLAG. Link to comment Share on other sites More sharing options...
