General welding questions that dont fit in TIG, MIG, Stick, or Certification etc.
After a bit of research it seems a blanket and coating i.e. kaowool and itc-100 seem to be the most efficient fuel wise. Not to mention easier to make and a whole lot light than a 2" thick layer of refractory cement.
Nowadays people know the price of everything and the value of nothing... Oscar Wilde
Look for a boiler wholesaler that deals in industrial boilers. You can get it in any form you want. Powdered can be mixed like drywall mud. Thin or thick as you like you can pour it in or make it like clay and mold it. They sell blankets from 3/4inch thick and up. 2 inch is the thickest I've used. Or you can get the solid bricks that you cut/ rasp into shape. If you need to PM me I can get you a phone number of a company I deal with a lot out of DesMoines Iowa.
I have more questions than answers

My old boss is a Redline dealer so he can get me refractory at cost so I have that end covered but the Kaowool blanket is going to be hard to get only because you have to buy a certain quantity and it isn't cheap. Do you know if they sell small quantities?Poland308 wrote:Look for a boiler wholesaler that deals in industrial boilers. You can get it in any form you want. Powdered can be mixed like drywall mud.

I have a call in to a friend at the refinery near me. He says he can get me some....have to wait and see but I appreciate all the help. Just got a price on refractory...approximately $160 for 2800 degree. $140 for 2400. My customer is so excited he's been texting me all morning...Poland308 wrote:I think they will cut off of a big roll a foot at a time. I thing the roll is 48inches wide.

I was looking a back in November or so for kegs for this. I found someone selling them in Sydney on ebay for 80 each. Seemed reasonable, I don't know what they are worth but I supposed to a homebrewer thats a pretty good price?
Anyway, found a guy today on Gumtree. Has about 10. Wants $20 each for them. I might buy 5 or even the whole lot. Make some BBQ's out of them and sell them. Gotta be some other good uses for them. Not sure why they are for sale, when do they cease being suitable for beer? Photo looks like the back dock of a club or pub.

I do quite a bit of keg modding for homebrewers. Some of them will only use brand new kegs while others will use aged ones. If you can find kegs cheap...grab them. You can always turn around and resell them for some extra beer money and they will never go down in value so I always have a few laying around. The guy I am building this furnace for was thrilled to know I had a keg for his project and the means to get the job done. Homebrewers, especially new ones, will spend money freely to get up to speed with their colleagues and not look like a noob. I don't know when/why they retire kegs..maybe when they get dented up really bad and the metals strength might be comprimised. Grab those kegs...thats a deal!Rupes wrote:I was looking a back in November or so for kegs for this. I found someone selling them in Sydney on ebay for 80 each.

I'd run the serial #s past any listed/stamped owner/distributor on the kegs, to be sure I wasn't buying a "hot property", so to speak. That price is remarkable, to say the least. I think I paid a bigger deposit than that on the last keg of beer I bought for a party 30 years ago.

Worst case, you might get a finder's fee if you do the legwork to confirm whether or not the sale is legal.

I've seen them on Kijiji in Calgary for $20 / 25 bucks, I've been thinking about using one on its side for a forge setup.

What fuel are you using? I have been looking into this for a project, and have been considering a waste oil burner. The web has a wide range of ideas on the topic.
If you don't mind a newbie question: how does your burner work? Do you mind showing an exploded view?

Looks good! If you want to control the gas flow get a regulator or use the ball valve but I wouldn't change it until seeing how it runs in the furnace.

I bought my TIG welder t go along with my aluminum casting hobby
My furnace is built from a 30 pound propane tank
You will find making your patterns to cast the parts to be fun, at least I do.
Follow the myfordboy link posted previous, he has a ton of good info, and has no blabbering while making his videos.
It makes them much more enjoyable to watch
Here's another forum you may find helpful- all about casting stuff!

BTW< you re headed down a long twisty involved highway.
You thought welding stuff took you off on rabbit trails, you start
casting aluminum and pretty soon you are trying to turn everything into a casting project
It is highly rewarding to be able to cast your own parts and pieces.
For casting alloy, forget anything extruded and pop/beer cans.
You want old pistons, cylinder heads, engine parts in general and anything
that was previously cast aluminum.
Wheels are about the highest quality aluminum you can get for the home hobbyist.
CHECK EVERY UNKNOWN PIECE before melting scrap to make sure it isnt magnesium!
vinegar is your freind

Thanks Jim! This is actually a project for a friend for his use but he is going to allow me to use it but I am going to make my own. Nice furnace you have there. I am not really happy with the refractory that I got. I used to build and re-line casting furnaces...BIG ones..and bought the material from my old supplier. It will work fine but it doesn't finish well but that's really nothing but a cosmetic issue, the stuff is great otherwise. I am looking forward to the molding though. And thank you for the links. I never knew home foundries were so popular. As I said, I have relined and built alot of big furnaces, the last one I did held #50,000 of aluminum. My old boss still does it but work has been slow for him as some of his customers have closed their doors. I poured the floor on Tuesday and the walls on Wednesday. I am going to strip it out today and I will post up some more pics. Thanks again for the help!Jim FLinchbaugh wrote:BTW< you re headed down a long twisty involved highway.

Its a very fun hobby!
Commercial refractory is way better.
I went home brew, portland cement, fire clay, pearlite and water.
They say it wont last as long as regular refractory but where I live shipping would have killed me
to buy commercial stuff.
Fabrication skills make this hobby much easier as you can build almost everything you need.
There is another youtuber goes by the name sandrammer. He spent 20 some years as a US Navy foundryman.
His videos are far from exciting to watch, and his delivery borders on painful,
BUT he provides some outstanding information if you have the fortitude to take it all in.
It prompted me to search out a copy of the US Navy Foundry manual and it was worth every penny of the 15 bucks it cost me.

The refractory is from Redline in Chicago and is an excellent product but IMO contains too much coarse aggregate so that's why it doesn't finish well. I stripped out the walls and had a little spalling but no big deal. Right now I have a heat gun in the tuyere and have it up to about 170 to dry it out. I will probably let it sit for a week or so before I cure it. I have no experience in casting, only building furnaces so I am rather excited about that aspect of the process. The guy I am building this for is an absolute genius so between the 2 of us, and the on-line help, we should be ok. My friend works for a drilling outfit so I have 200lbs of powdered bentonite and 500lbs of fine silica sand on the way so I am pretty excited. I will eventually build my own furnace but this one is a great learning experience for me. And you're right, being able to weld and fabricate sure opens up a lot of doors into innovations. Thanks again for your links and I appreciate your feedback!Jim FLinchbaugh wrote:Its a very fun hobby!

Thanks Rupes! It didn't require too much weld/fab but most of us are do-it-yourselfers here so I thought it might be interesting.
Ifyoucantellmewhatthissaysiwillbuyyouabeer.
I think its fantastic. Its one of those things that open up new ways of making things you never thought of before. Who needs a 3d printer that makes useless nicknacks when you can melt down some scrap and pour your own castings.
