FieryFurnace Posted April 27, 2008 Share Posted April 27, 2008 Alright, I was going through the barn and I came across some old pieces of steel. They are some kind of blades, and I think that they might be old tiller blades. I also found an old piece of a plow. You know plow points, well this looks like the piece that the plow point attaches to. It's the piece that comes down and bolts to the back of the plow point. What kind of carbon content are we talking about here? What would it be good to turn these into? I'll ask how to forge them later.

Dodge Posted April 27, 2008 Share Posted April 27, 2008 If they were old tiller blades, or any other old blades for that matter, they can usually be made into new blades Not sure about the other steels but if it had to do with plow tines, its most likely hardenable steel and could be made into all kinds of tools depending on the dimensions: Chisels, punches, tongs, hammers(?)

pete46 Posted April 27, 2008 Share Posted April 27, 2008 1080 or 90 ? PLOW ARMS HAVE TO FLEX TO SOME EXTENT. THE TILLER BLADES ? TEST THEM, SPARK OUR HEAT AND QUENCH . Quote Link to comment Share on other sites More sharing options...
Donnie Posted April 28, 2008 Share Posted April 28, 2008 I can't say what tiller tines are made of, but I have made knives with them. Hardened in oil, tempered at 425. The tines made nice blades, maybe just because I didn't know any better.;) Quote Link to comment Share on other sites More sharing options...
FieryFurnace Posted April 28, 2008 Author Share Posted April 28, 2008 1080 or 90 ? PLOW ARMS HAVE TO FLEX TO SOME EXTENT. THE TILLER BLADES ? TEST THEM, SPARK OUR HEAT AND QUENCH . O.K. I know that 1080 and 90 have to do with carbon content, but I don't know if that is high or low carbon. What does "spark or heat and quench" mean? Does that tell you whether it's 1080 or 90? Please clarify somewhat, I am eager to learn.

The tines made nice blades, maybe just because I didn't know any better. How long do you temper them at that temperature? I am working on my first knife, out of a file, and I was told to temper it at 250, I think, for a couple of hours. Is that higher or lower carbon content? Thanks!

rthibeau Posted April 28, 2008 Share Posted April 28, 2008 using the blades as a starting point, why don't you try to reverse engineer it and make a TILLER?? Quote Link to comment Share on other sites More sharing options...

philip in china Posted April 28, 2008 Share Posted April 28, 2008 Why not turn the tiller blades into a tiller and the plough blades into a plough? Quote Link to comment Share on other sites More sharing options...
matt87 Posted April 28, 2008 Share Posted April 28, 2008 Regarding AISI steel spec numbers, as a quick guide the first two digits indicate the alloying of the steel and the second two that emount of carbon. For instance, 1080 indicates a plain carbon steel (10xx) and 80 points carbon (xx80). Carbon is expressed in points, one point being one hundredth of a percent. Thus 80 points = 0.8%. This is considered a fairly high carbon steel. Steel contains typically between 10 and 220 points carbon. Below that it's pure or wrought iron, above that it's cast iron.

FieryFurnace Posted April 28, 2008 Author Share Posted April 28, 2008 I'm in the 10th grade at age 15. 10xx is supposed to be written 10x2. Oh, did you want me to write a formula for that, or is it a graph. Just kiddin'! Thanks for the info. For now, I think I'll stick with mild steel.

matt87 Posted April 28, 2008 Share Posted April 28, 2008 FYI, mild steel is around 1020, or a little lower. Nowadays, 'mild' sees to mean 'some stuff and less than 30 points carbon ) Nothing wrong with mild, it moves easier, is more readily available and is less sensitive to heat.

hammerkid Posted June 23, 2008 Share Posted June 23, 2008 1080 has .80% carbon. , 1084 has .84% Carbon .. I got some tiller tines myself the other but ain`t had time to use them yet. Quote Link to comment Share on other sites More sharing options...
Donnie Posted June 24, 2008 Share Posted June 24, 2008 How long do you temper them at that temperature? I didn't ignore the question. I just haven't looked at this thread since posting on it. I tempered the tines at 425 for 1 to 1 1/2 hrs.(keep in mind I AM NO EXPERT). Quote Link to comment Share on other sites More sharing options...
