This story Arc  is well grounded if a bit re-volt-ing.  Beginning to remind me of the time I got stuck in an electrified barbwire fence while wearing a chainmail shirt...

Weeks and months of working from home and *now* I have to be in the office while they wire my shop.  I bet they think they planned it that way on purpose!

Alexandr, may I ask what type of forge you use and how big it is? Those long twists are so even and consistent! Are they each a one-heat-twist?

I twist it without heating. 2 fixtures. The first is for a square of 14, 16 mm, the second is 10, 12 mm.

It is also possible to twist several round bars

Alexandr, that's brilliant! I haven't been smithing long and I wouldn't have thought of twisting as much as 16mm square, cold under "human-power". I love simple but effective use of leverage/mechanical advantage!

Cheers,

Jono.

I've always liked building a shed roof on a structure you think you might want to expand. Looking good, happy growing!

How large are the nifty boxes? They look handy, I like square it wastes little space around it.

Has nobody told you clay IS natural matter? -_- Or did the cute puppy donate some of the bucket's contents? Seeing as I kind of like you I'll suggest you sort THAT natural material out. The inclusion is nothing to sniff at!

Ah, the timeless grader, dozer, plow edge question. We should have a sticky with the answer at the top of every page. The only reasonable thing to do with worn cutting edges are see what the scrapper will give you for them. 

Cutting edges are tempting, they're hard steel and just laying there, heck they're CALLED knives in lots of places. I grabbed a couple, still have a short piece of unused grader edge trimmings from work. One of these days I'll silver brae it to a cast iron ASO somebody left here. I've been saying that for at least 20 years and both are still waiting.

The stuff is pretty much unworkable in a home shop. You can cut it with a torch. If you want to grind it you WILL need diamond abrasives. Cutting edge is typically 1.5-2% carbon matrix for IIRC 2% tungsten carbide. It's NOT low alloy either, edges don't snap. I've personally caught a manhole at roughly 15mph in a 72,000 lb. Champion grader and been stopped cold. The only movement after it caught the manhole was the moldboard and edge bending and not much.

Sent me home for a couple days, sprained my wrists but I was seated and belted in or I would've gone through the windshield. 

Tis really is about cutting edges, I don't know more than a little of what the alloy is, but it's not something you're going to be able to forge without damaging your hammers, power hammer dies and probably anvil face. 

My advice is to leave it where it lays.

It has a lot of thermal mass and will chill the blades quickly. I don't know if it'd be a factor unless you put them in at critical temp in which case I expect it'd quench the blade and seeing as it couldn't have 100% contact over the entire blade it might do ungood things.

Thinking about that just now Not being in full contact might effect things. 

I do recall something useful a smith made with grader edge, a shear. Hinged the blades through the mounting holes and used it to shear bar. Wouldn't work on thin stock it couldn't be sharpened but from what I recall hearing it worked a treat on 1/4" and thicker bar stock.

Is this true for auger teeth as well? I’ve had my eye on a couple of worn out teeth at work for bottom tools.

I'd get the rocks out if there are any. Any organic matter shouldn't make much of a difference. Some folks add straw to make cob.

Grader blades: weld up into a work table with hardy holes in it.  Try to scrounge the ones with square holes the same size as your anvil's hardy hole.  (Took me a while to find one with 1.5" sq holes!)  

If your improvised anvil lacks hardy holes,  make an improvised hardy hole!

Grader blades tend to be abrasion resistant steel, a pain to work and not a good alloy for blades!

No. They're typically forged with a tungsten carbide insert silver soldered in place, just like a carbide lathe cutter. Once you remove the carbide and remaining silver solder you might be able to forge things from them. I don't know you'd have to evaluate them like any other mystery metal.

that sounds similar to grader teeth I've dealt with they had a 3/4" carbide on a mild body and a small piece of sheet as a spring to hold in place if same bantou i would leave them where they are

yes my father and i got the roofing up last night  so by next weekend it should be done

the boxes are 13" squarish (no 90s in corners) 

frosty:rolleyes::wacko: even p nut knew better the material i talked about was dead leaves, sticks ect the clay came from a freind so the dog didn't do it (one of their three maybe?) no the stuff i got was clean of that material
