It followed me home (Part 2)

..Splashing of a quenchant cannot result in an uneven line of HT...(i THINK i'm fairly certain of that...An uneven heating may....however likely that may be in a factory setting(a rack of tools travelling through a gas forge...

Vaughan evidently (and differentially) heats its head in a "molten bath" before quenching, as seen in this video (starting around 3:30). I surmise (perhaps incorrectly) that the whole head would be quenched after only the bits are heated.


As posted in another thread:
Some types of salts can evidently be used in "molten baths" for heat treatment:
"Salt baths are available for operating at either tempering or hardening temperatures. Depending on the composition of the salt bath, heating can be conducted at temperatures as low as 325° F to as high as 2,450° F. Lead baths can be used in the temperature range of 650° F to 1,700° F."

Thanks,both you gentlemen...Steve,that stands to reason,High Temperature salts are a good,reliable, industrial method of heating steel ...
Alas,my own HT experience is very limited,and basic,but i have been asking similar questions amongst those much more knowledgable...What few opinions have been tentatively volunteered were cautious,kinda hard to say sort:)

And still it remains a mystery-what exact physical process can create a darker hardened edge on monosteel?(one visible in a very low level of polish,practically grinstone/file sort of grit,or not far from....)?

On many an older vintage American axes that exact same contrast is most definitely a forge-weld...Not often,but occasionally it is evidenced by an inclusion,or a welding flaw of whatever other sort,clearly following the color boundary.
 
Thanks again,guys,cool videos...

But here we have it,from the brochure about their manufacturing:"...The depth of the hardening on the striking face is just as important as the degree of hardness. Unfortunately, since hardness cannot be seen, it is often neglected, affecting the hammer's durability and making it a potentially dangerous tool. ..."

I don't know how to underline stuff,but you see the sentence i'm getting at...
It's not Strictly true,Differential HT Can be seen under some,very special circumstances(not counting microscope:)),but it takes much work and care(as any knifemaker will attest),and will appear Whitish,lighter than the untreated part of alloy...
 
here you guys go, there were a few other things, like a 24" size 13 drill bit, a wire brush and a 5 inch file.

from left to right, no name adze, no name phantom bevel, probably a kelly, old straight 36" handle, no name 3.5 pound jersey, and last but not least, the 4 pound spiller. pretty heavy pitting on the other side but none on the bit.

everything cost my $3

i bet you can guess which head the handle went on
 
The family and i left for a week of camping, we are three days in and I have been itching to share...
Saturday morning as I headed to the hardware store I stopped at an estate sale that happen to be just up the road.

This is some of what I scored, all $1 each

This sharpening stone/grinder was $10

There are a few more :)
This newbie is super excited to get home to my score!!
I haven't told my wife about the new score and I had to cover up why I was gone to the hardware store for over an hour...to get gorilla tape LOL!!

Aren't top drawer tools meant to be used? Without the stamp you might have continued to abuse it and discovered (over a long period of time) that it held up pretty darn good.

I'd certainly still use but take care of it.
it would be a shame not to use a tool which was meant to be used that should be able to take it.
 
the issue was i was treating it like a modern hammer, head loose? slam it on the anvil. left it out in the rain? only mild panic. i was abusing the poor guy and now its just a shop hammer. i needed a heavier hammer anyway
