671jungle Posted November 15, 2019 Share Posted November 15, 2019 They will be my first spark test. Printed out a spark chart but no known steels to compare with. I am pretty excited about this. Quote Link to comment Share on other sites More sharing options...
pnut Posted November 15, 2019 Share Posted November 15, 2019 Try progressively faster quenchants along with the spark test. Then you'll have a good idea of how to go about the HT. Pnut Quote Link to comment Share on other sites More sharing options...

ThomasPowers Posted November 15, 2019 Share Posted November 15, 2019 And can't access any water or make a brine (salt water)? Must be a dry county... Now as to large section steel found near a truck place and Machine shop I'd check against 4140 and perhaps 5160 samples. Most likely to be hammer making material and not blade material. Possibly mild; but I would doubt it for the hex end stock. Quote Link to comment Share on other sites More sharing options...

Still doing my homework. Brine sounds interesting. I have not quenched anything other than fooling around when I first started. Now that I have had some practice with the hammer, and general determining what scrap WAS used for, I feel it is time to start making useful things and testing them. As far as "dry" Utah got some weird booze laws. The grocery now sells 5% as of a couple weeks ago. It used to be 3.2%. Anything more must be purchased at the State Liquor Store (DABC). The limited license bar and restaurant industry consistently gets popped for meticulous violations. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted November 15, 2019 Share Posted November 15, 2019 Now if you want a bunch of weird quenchant suggestions, may I commend to your attention the list of Renaissance suggestion in "Sources for the History of the Science of Steel". Radish juice or worm water anyone? Quote Link to comment Share on other sites More sharing options...
BillyBones Posted November 15, 2019 Share Posted November 15, 2019 That does look to be the end of a torsion bar. When i first joined the Army i watched a video of a tank flying threw a field guns a blazing jumping hills. The part they did not show was when the tank landed off that hill the crew had to get out and replace all the broken torsion bars. Radish juice? I dont think i want to know what worm water is. There is a way to get a perfectly hardened and tempered blade from any steel. But it involves 2 goats, a pint of whiskey, and hiking up a mountain side for the egg of a giant condor.

ThomasPowers Posted November 15, 2019 Share Posted November 15, 2019 Turns out you can do a similar one with two curmudgeons, a hogshead of rum and an Ostrich egg if it's really fresh. I'd show you my scars but Glenn would ban me for life + 3498672 years. Quote Link to comment Share on other sites More sharing options...

If it does clamp it in the vise cover with a rag and give it a whack with a hammer to break it. Examine for excessive grain growth. Then repeat the process with warm oil and finally brine. I don't have any pictures of the difference in grain sizes to post to show you what good looks like but I bet if you check the HT section you'll find some and I know you'll find better instructions. Pnut If it skates a file after air hardening or oil quenching there's a good possibility it will crack during a brine quench.

Some energy taken to snap those babies! worm farm bins leach a viscous blackish liquid that is used in the garden. Might be a "perfect" quench all. I have not heard the term "hogshead" in years. Used to have a notebook with a chart of different and unusual measurements on its front inside hardcover. I remember hogshead being on that list.

ThomasPowers Posted November 15, 2019 Share Posted November 15, 2019 I don't think that is what they were using. I can look it up this weekend as it's on the shelf in my study; but can't post till Monday. Heavy work for mines can snap quite large shafts.

671jungle Posted November 16, 2019 Share Posted November 16, 2019 Pic of the broken shaft with what looks like the break origin point. And everyone’s spark pics. Just gotta find that chart Quote Link to comment Share on other sites More sharing options...

That viscous black liquid is humic/fulvic acids. Not sure on its quenchant qualities, but may be an option to get contrast for PWS(pattern welded steel). That stuff will stain your hands for a week Quote Link to comment Share on other sites More sharing options...
CrazyGoatLady Posted November 18, 2019 Share Posted November 18, 2019 This followed me home Saturday for my birthday. Full and everything. Haven't used it yet, but it'll sure beat those 20lb.ers. Quote Link to comment Share on other sites More sharing options...
Eventlessbox Posted November 18, 2019 Share Posted November 18, 2019 CGL, Happy Birthday:D cant wait till I upgrade to a tank that size. I’m still using a couple of 40# tanks that came from my old RV. Still hoping I can get my propane supplier to hook the forge to the big 250# tank that was for the single wife we don’t use.

BillyBones Posted November 20, 2019 Share Posted November 20, 2019 The old lady went and did her taxes the other day, she does some kind of extension thing so she does not have to file till Oct. then gets her return for Christmas. I been talking about needing a new welder since mine quit working. It was just a cheapy HF wire feed so i was not real concerned. But anywho, this was sitting on the table when i got home. An early Christmas present she said. Yeah its not a top of the line but it will most likely do me for a while and seeing as to how it was a gift from the old lady i am happy with it. She also managed to get 7018 rods just becuase they were the ones closest to the welder when she was getting it. Now to make my guillotine tool...and more tongs.

Chelonian Posted November 20, 2019 Share Posted November 20, 2019 Please let me know what you think of it after using it for a while. It's one of the welders I'm considering. Quote Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted November 20, 2019 Share Posted November 20, 2019 I've seen some reviews and they were all positive. A DC welder is easy to use. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted November 20, 2019 Share Posted November 20, 2019 Definitely not top of the line---but also definitely not bottom of the barrel either! Quote Link to comment Share on other sites More sharing options...
