A6 graphite crucible 4.5 Lbs 5160 1.5 Lbs white cast iron Broken glass for a crucible cover From chapter 13 of my second book, on making wootz It is important to know the carbon content of the cast iron you are going to use. We already know the base metal of 5160 is at roughly 0.6%. Weigh out the amount of 5160 and adjust the amount of cast iron to come up with a final total of around 1.5% carbon. Being a little off will not be a problem. Place the charge into the graphite crucible and cap with a covering of the broken glass. Furnace temperatures will take 60 to 90 minutes to reach above 2700°F (1500°C). Then allow 15 minutes to rest at temperature before placing in hot box to cool slowly to room temperature. Upon removal from the crucible, if the color of the Wootz puck has a very brassy appearance, it could indicate that the carbon content is too high. Any over-carburizing of the ingot from the crucible will turn the steel into cast iron

It is good that Electricians get paid on time

I was wiring in the main feed for power on a stage job and the sound engineer was upset I used too large a wire for the feed, he said it will draw too much power

I can get you a certification from Miskatonic University

For all you know Frosty is a mod, most the staff here use MOD# accounts to do their jobs. the point is you are a wonderful artist, but a lousey exhaust designer. It is dangerous and you dont seem to understand that, and for the record I am staff, but the last upgrade to the forum removed the visable tags from my profile; and I had thought about closing this thread to avoid more BS, but will allow it to finish itself

or read the sections on IFI about heat treating, there are a few posts that address your issues

I know how to teach a 5 yr old how to use a flash bang grenade, its also easy; but I am also smart enough to know not to do so, for the same reason I wont give wiring instructions on an open forum to people that wont follow directions

I hold a Masters rating as an Electrician,and have been licensed since 1984, I am not going to be able to train you to be a responsible wiremen in a few posts that you wont read anyway. This is not a wild statement as you have proven this by ignoring the posts you were directed to read when you joined, and you also ignored the PoP and Sand mix threads you would have read if you really wanted to know about it

If you have to ask about such a basic electrical question, then I highly advise you to hire the wring out to an experienced electrician and NOT do it yourself

1/4 inch is huge

I also have to comment that its not advised to share the stack

In my apprenticeship I learned to edge pack as well, but the problem is that edge packing doesn't work that way because anything done to the grain during the 'edge packing' phase is undone during the thermal cycling of the heat treatment process, what it does do is give a smoother finished product as a result of the blows given as the temperatures get lower

Odd that you would tag this to a 10 year old post.

A2 for a sword ? wow

you need to give us more info that that, can you post a photo?

I heard it as ya cant tune a fish

the Wilton I learned on was under powered, with only 1 HP. And it needs at least 1.5

cant make Martensite if there isnt enough carbon available to form it, no matter how fast the temperature change. Super quench helps to form it from what is available, but that is no substitute for having enough martensite

I wrote a few articles on heat treating, rather than make wild guesses, I suggest you read some, they are pinned to stay at the top of the page. One can not harden steel if it does not have enough carbon, because the act of hardening is trapping carbon in the iron matrix. which as I said many times can not happen if the carbon isnt there, and oil does NOT add any carbon, another myth, but case hardening does add carbon 46 points of carbon is very hardenable, its called medium carbon steel; which is no where near 1020. Mild does not function the same as tool steel, more myths, and from a cost perspective: tool steels would not be made if the mild would perform the same way, the additions of tool steels help in reducing grain growth, defining the grain boundaries, hardenability which is not the same as hardening and carbide formation

remember King of Random, from before he got himself killed?

Hardened blades will hold an edge better

you also need to remember the loss of carbon happening during the forge welding process, but that is partially how blister steel was made
