  1. I enjoy the book, especially the thrifty 'scrounge-and-make-do' attitude, though I must say I was a little disappointed. Perhaps I was expecting a book with more emphasis on forging than grinding and sawing. It is of course a product of its time and some of the practices are... best avoided for safety's sake. There is no discussion of welding beyond 'it's cheating'. Furthermore although the three titles are now contained in one handy volume, I find it awkward to have to search for something in three different indeces and then find a lot of duplicated information.

    Just some minor niggles I suppose, it's a good book overall!

  2. a while back i sent in a blueprint to make a smiths hammer ,it seems to have gone ,along with a blueprint to make a pr of pincers out of a rasp, there were lots of blueprints all very helpful and well presented that disapeared ,perhaps they can be reteived


    Those particular blueprinta and many others are currently offline due to a technical issue. Glenn and the other staff assure us that a solution is being sought, and that the blueprints in question are safe.
  3. 1) would this be a drift or a punch?
    If you drive it all the way through the iron and it drops free, it's a drift. Else, it's a punch.

    2) is a HC RR Spike considered Tool Steel? If not, what would it be?
    IIRC the specs call for a maximum of 0.3% carbon and 0.2% copper. Not tool steel, mild steel. It's not what a lot of knowledgeable people would consider a good choice for a blade since it won't hold a very good edge. However it is slightly better than the copper-alloys used for a long time before steel became widespread. If you really want I suppose you could lay in a bit of high-carbon steel, though mild steel is certainly adequate for 'wall hangers'.
  4. Do you think that A36 will absorb too much of the hammer blows? Sorry. I just heard someone say it so I had to ask.

    It will work just fine so long as you don't hammer the material when it's cold.

    edit: can A36 be harded in a coal forge and quenched with water or oil to make it harder?

    Theoretically yes, in practice not any appreciable amount. You're better of using that fuel for smithing! :)
  5. Why did or do they create cast iron anvils with steel faces? Seems like by the time you do all that work you might as well just pour steel. Especially with the fact that cast will never fetch as much. Is it just because the heat for cast iron is much less? Is that the only factor? Or is it also price of ore? all of the above?


    Steel used to be very expensive. Furthermore it was only discovered how to cast steel directly into a useable tool in (I think) the 20th Century; before that 'cast' steel was poured into ingots then forged to shape. So far as I know, no-one produces cast-iron anvils with steel faces (commercially).
  6. This may echo UnicornForge a little...

    I've not yet got around to forging wrought, but the received wisdom is to work it as hot as you can; it's not steel so it burns at a higher temperature -- white is typically mentioned.

  7. Coke is an odd fuel; it seems reluctant to burn and indeed makes for a fairly good insulator but when it does it is very good. It doesn't need 'topping up' with charcoal so long as you don't let it go out.

    Where did you buy the coke from YISS? Was it in bags? There's only a few 'brands' available in the UK so I'm sure someone on here has some experience.

  8. Welcome to the forum YISS. It'd probably be wort your while adding your location to your profile, you never know when theree is a smith just round the corner able to help!

    The smithing coke we get in the UK is known as breeze and yes it does take a fair amount of heat to get going. Firelighters do not, in my experience, get hot enough on their own, though they work fine for lighting the next stage of the fire ready: a good wood or charcoal fire. Once there's a good solid fire going I then work the coke in from the edges of the fire, being very careful not to choke it. Takes a few minutes from striking the match to putting steel in the fire.

  9. no, i am stating that in my experience with rebar (god knows what type/quality) i've found just because its looks hot doesn't mean i can take a 3# hammer to it and expect it to move the way the mild steel of the same girth i just got done working with did. even hot the rebar seems to fight back and retain shape. there for it would require longer heats to work easily. and as for your tool steel numbers they may as well be Japanese. because i work in scrap. i don't know the numbers, i know that working 1/2in rebar requires a longer heat in my propane forge than most of the random 1/2in scrap i pick up does to work. who knows maybe the 1/2 inch rebar i got is magical, i know at a dark orange i may as well be hitting my anvil instead... i may make more progress! and if it is magical what do you think? +1 or +3 rebar of zombie slaying?


    Okay I get you now. The property you're describing is commonly known as 'hot hardness' and is common in steels with significant amounts of carbon and other alloying elements. As is commonly said, lower-spec, garden-variety rebar is typically made to a performance (rather than material) spec from remelted scrap and so often contains a lot of whatever 'stuff' happened to be in the scrap hopper. It can be a useful property if it's worth the time/embuggerance factor to work with 'found' steels rather than 'known' ones.
  10. also keep in mind that rebar is rough to heat. depending on the quality of rebar your playing with, your going to need a serios fire going to heat it to dark orange or better. i run propane and i spend almost twice the time heating rebar as i do almost any other stock.


    Eh? Are you saying that, if you were to put a piece of rebar into your forge next to a similar sized piece of A36 or 1045 or any other steel, the rebar would be considerably colder than the other piece?
  11. I've lit charcoal and coke fires with several different methods and techniques and IMO nothing beats a decent wood fire to start with. I have been known to use all sorts of things to start the fire, even 3-in-1 oil soaked into cotton wool (works but smokey). Now I avoid accelerants -- I've never had an accident but the risk is there and frankly I can light a fire without them just fine. My favourite way (probably make our Scandinvian smiths happy) is birch bark and split, dry pine. I'm very careful with stacking the fire, adding fuel and air as needed (easy to get carried away and choke or blow out the fire) and can usually get a forging fire ready in under 15 minutes with one match (I forge outdoors in my native, damp habitat). I find that with (industrially burned) coke it's important to have a good bed of (wood) coals roaring before raking the coke into the edges of the fire gradually (it's a bit of a bugger to light and comes sopping wet). A handful of lump charcoal helps it get going.
