Hello,
I want to buy an furnance for knife making, and i don t know which are the features i need to folow, as i am new in making knives.i want to know the temperature maximum usually used for hardening steel? and another question-does anyone know how amber stag is obtain?thank you verry much for your help
 
Welcome to the forum!

For me there were two variables I was interested in. Size and maximum temperature. Evenheat has a 26-27" model that goes to maybe 2100*f and for about the same price you can get a 22" model that goes to 2300*f. I was going to go with the larger model and decided that the extra couple of inches wasn't enough to do swords or machetes so I opted for the smaller kiln and higher temperature. I figure I can buy or build something 36"-48" down the road. I should note that you can do most steels with the 2100*f model, I was told the more complex stainless steels are mainly what requires the higher temps.

Now in Romania I'm not sure what options you have or who sells or can ship a kiln over there. I imagine you'll be facing the same choices though. Show us what you get, I'm curious what is available over there, I've only seen homemade kilns used by European makers.
 
Thank you very much for your answer and explanations,
Here you have a link where you can find what we have in our country, i asked about the price and they say it s about 1000 $ at 1000*C and the price doubles with every 100 degrees.
i bought a KMG belt grinder from US, i m so anxious to see it,but i ll have it in two weeks, i was ready to buy the furnance from there but the shiping is expensive, especialy with so many kilos...
Do you have any other recomandation for furnance from US?

here s the link

Evenheat and Paragon are the only two that I know of that make furnaces specifically for knives here. That's unfortunate on the shipping, mine did come on a large truck and not the standard means like UPS or FEDEX.

Those kilns would work though you would have to bump the temp up a few degrees. 1000*C is about 1800*F. I'm not a knife making expert so I'm not sure what you would want for a minimum, I would stick to around 2100*F to be safe but that may be overkill for you if you plan on sticking to simple carbon steels. Higher than 2100*F if you want to use some of the alloy steels out there.

The other issue I noticed is size, at least on what I saw from the link you posted. That looks more like a dentists oven to me. If its 180mm deep you have to figure about 25mm of open space on each side so the blade isn't too close to the coils. So a max knife length of around 155mm if you put the tang right up to the door and some say not to do that.

If you are comfortable fabricating your own tools you might look into building one, there are several threads on here where guys bought parts from a supply house or Amazon and built there own.
