brazing brass bolster (question)

esa · Oct 14, 2005

hello,i had a question on brazing brass bolster's onto D-2,i have done alittle and still in need of practice,but its comeing along,the question i have is should i wait until i have heat treated the blade then braze the brass on? will it hurt the hardness of the blade?,i think it is bolys book?i cant remeber his name but he said to braze before heat treating,but brass starts melting at 1750 and D-2 needs 1850 to treat,has anyone got information or doing this style of work on there blades.
thanks eric

Do the brazing after the blade is hardened and tempered. If you are carefull you can do it. Also you can wrap the blade in wet kitchen towel as a heat soak and heat the tang. I have also found cucumber works well.
Here is a link I found usefull-
