Hmmm...what's on today's menu? What? More knife making? Sounds delicious!
grinding bevel with a 120grit ceramic disc on the 9" variable speed disc grinder. This allows me to check and make sure the bevels really are flat;
there was very little material to grind off for the clip, so I just rough filed them in for heat-treating;
the edges of the blade are at 120grit now, but there are sharp edges... mostly just as a precautionary thing, I go over the blade with a 10" buffing wheel and 240X Polish-O-Ray compound from Brownell's. This stuff can throw sparks! But it leaves the blade with nice smooth edges;
sitting on the bench, cleaned up with Acetone, and ready for its trip into the salt bath;
It's the salt bath.
this is what the heat-treating salts in a salt bath look like when they're at room temperature;
this is the salt up close when it's in its working temperature range... 1600F to be exact for this pic;
the blade ready to be dipped in the salt... note the leather welding jacket. 1600 degree liquid is not something you want on your skin!!!
the blade coming out of the salt for one of the initial, high-temperature cycles. It was about 1600F in this pic;
an overall view of me pulling a hot blade from the salt;
the blade out of the salt, up close;
the shadows entering the blade as it cools off after coming out of the salt;
