Thermal Cycling/Normalizing Questions
I'm working on a short-ish blade right now, and I'm trying to make my chances of a successful heat treat as high as possible. I know all most of the basics and some of the chemistry, but I still have one question: What is the best method of thermal cycling/normalizing? I know that you should get it to crit temp then let it cool to black, or room temp, but how many times should I do this? What I've been doing is heating it up to crit, letting it cool to black (I do that three times in a row) then I heat it a little bit above crit and let it cool to room temp, then I heat treat. It's worked so far, but y'all probably have more experience than me. Thanks, Jacob

Propane Regulator
I have recently built a Frosty Tee Burner for a gas forge of mine. Is it absolutely imperative to have a regulator attaching to the propane tank? There is already a valve on the burner. If I do absolutely need one, can someone point me to where I could get a cheap and good one? Thanks, Jacob

Firebrick decision
There are two types of firebricks: hard and soft. From what I've heard hard firebricks take longer to get hot but are cheaper than soft firebricks. And soft firebricks the opposite. Is it imperative to use soft firebricks? I mean I'm making my first gas forge and I have a budget limit. Getting the amount of soft firebricks I need could cost upwards of 70$ usd. But hard firebrick from like homedepot could cost only 30$ usd. Which do I choose?

Lean, rich or just right?
I just recently built a Frosty T burner. I bought 0.035 and 0.025 mig tips. The 0.025 worked best for me though I used a strange setup. Experiment with grinding the tip down a little. You could also try regulating the amount of oxygen that gets to the gas.

Firebrick Forge Without a Welder?
So I assume this has been covered 100 times before, but hear me out: I recently built a Frosty T burner. (And it works pretty well) I had planned to make a gas forge with kaowool and a propane tank, but I learned the extent of the dangers of kaowool. (I already knew it was bad but not this bad) I know there are refractory sealants to protect me from the fumes but I don't want to take that risk. So I want to build a gas forge with firebricks. The issue is: how do I build a stable firebrick forge without welding (and with a low budget) I still don't have access to a welder. I've looked around a lot for info on this and I've found nothing. (Loads more time than an hour this time BTW...) If I made a forge would the brick would I need refractory cement to seal it? Do I even need to support the bricks to make a stable forge? And what type of bricks do I use: soft or hard?

Possible Burner Idea?
Thanks, do you think that the frosty t design would work? It doesn't seem too complex, but is it one of those tried and true methods? The one I ended up building for the foundry was Grant Thompson's Gas Blaster. It worked well, but it was a very complex build. It could be adjusted better, but in the end, was just needlessly complex. That Ron Reil also looks pretty good.

Possible Burner Idea?
Yeah, that's what I was plannin'. Sfeile, I wasn't complaining, I was merely expressing my misfortune with finding information. I have used very similar propane burners before. I was looking for a simpler design than the ones I have made. When I worked on my aluminum foundry I spent months of work on researching. I expected my knowledge to carry over even a little... Read note to Sfeile, the same applies to you.

Possible Burner Idea?
Though I have already checked many forums for burner blueprints. (Like for a stinkin hour) I had not found any that were simple or cheap enough for me. The "Frosty T" looks great and is what I'll probably end up using. Thanks for the suggestion! If I went with this model I would use a tap.

Possible Burner Idea?
I found this youtube video on making a simple burner for a gas forge. I have made a burner to melt aluminum in a foundry before. With most burners (and the one I made) I find that they cost a lot to make or require a lot of up-keep. This one seems almost too simple. What do y'all think? I'm not looking for it to last my whole life but to just get started in gas forges. https://www.youtube.com/watch?time_continue=5&v=67rxU02fv6o (P.S. I would make quite a few modifications like an air flow regulator and such.) Your boi, Jacob

Gas Forge Confusion
I am looking to upgrade from my coke forge to a gas forge, and I don't quite know what to do. I can buy one of those fancy centaur forge ones for half a grand, buy one of those ebay ones for 150$, or make my own. It would be hard to get enough money to afford the 500$ ones, and I don't have access to a welding machine currently. What do I do? Thanks, Jacob

Railroad Tie Plate Anvil
I walked around a railroad track recently and found two tie plates. Stacked, they weigh 54lbs. I'm wondering if they could be used as a starter anvil. They make an amazing ring and have good rebound, but they can dent somewhat easily. I have access to railroads, and should I go with this or try to find a piece of track just laying around another railroad? Thanks, Jacob I'm also wondering if there is a rust protection galvanization on it. That could be a reason for the denting. I haven't cleaned off all the rust yet.

Finding Scrapyards for Makeshift Anvils
I live in Austin Tx and I was wondering if anyone around these parts knows of any good scrapyards for hunks of steel? I need some giant hunks of steel for a first anvil. I can't seem to find any good scrapyards. Thanks! Jacob

Tough Anvil Choice
So my friend and I want to start blacksmithing. We have already quite a bit of experience with heated metals and we already have a forge. The question remains: what anvil do we choose? We have a budget of around 50$. We found a piece of railroad track for 30$ which is around 30-75 lbs. The only issue with this one is it doesn't have a horn or hardy hole. We also found a 20lb anvil on Ebay for 50$ it has a hardy hole and a horn. The only problem with this one is it weighs 20lbs! We don't know what to do! Does anyone have any suggestions? Our goal is to make a forged rebar bracelet and or a few knives. We also found a few Harbor Freight ones, but they are of awful quality. (A.S.Os Ya know?) Thanks! Jacob
