Annealing: 690-720*C about 2h then with kiln to 600*C
Hardening: 780-800*C for 10-15minutes
Quench: 50*C water
Tempering : 200*C for 2 hours , then temp drop with oven
Hardness : 59-62HRC

I don;t have my own Kiln, and HT making my friend.

I collecting $$ for EU version Paragon KM-18D with 12 key sentry, gas inlet, mercury relay, USB out, S TC , solenoind .

Have your tried quenching in oil? Like warm canola

Interesting! Is there some sort of release agent applied to the blade before pouring the epoxy? Hadn't heard of that technique before...

No, there's no release agent. With a few exceptions, if it doesn't say "Acraglas" on the side of the can, it will come right off with just a bit of prodding. Worse case a bit of heat, but that's generally not necessary. I learned this while evaluating store bought adhesives. The "glue" you can buy at places like Lowes isn't very good glue but its predictable and repeatable poor bond strength make it excellent as a temporary fixture.

I prefer the loctite 5 min epoxy for this because the epoxy is relatively strong and somewhat rubbery with very poor adhesion. The Devcon sticks a little better and is so weak that it falls apart leaving little bits of epoxy clinging everywhere that is more difficult to clean up.

You can also use bondo for temporary fixtures, but it would have been ill suited to this project because I wanted some adhesion.

I'm adding some glass powder to the epoxy to make it very stiff to minimize vibration related chatter problems.

80CrV2 is not oil quenching steel. ( Oil is to slow to this steel)
This is stricte water-quench steel.

But you can try both.
Canola and water.

Very cool Nathan! First time I've heard a good use for that '5 minute epoxy rubber' they sell at the hardware store!
 


My saw blade kitchen knife I started a whileago, got some shapeing and cleaning done, rough ground and ready for handling.

Got some yew to cut to shape and thin out, then it'll get glues and clamped for an overnight dry!

Samon,
That's looking good! Keep at it. I want to see it finished!

Thanks man!

Great to hear encouragment from one of t pros!

Sadly my belt sander crapped out on me today, I think I can repair it but I really need to invest in a bench mounted belt grinder. I have no garden or shed so space is limited but I will find a way! XD

Samon,
Feel free to PM or email me if you have any questions? I will gladly help or send you in the right direction if I can.

My first real big boy grinder that I still own and use some 18 years plus later is one of these 2 x 72" machines.

I am finishing up on this bad boy...

8" S35VN blade with a hammered finished guard and some sting ray and silver dragon menuki.

Finished wrapping the handle last night it took several hours but came out nice.

Adam,
That it one fine looking Tanto and it looks even better to me personally because you made it with a traditional tip and length.
 
From a few pages back, keyhole integral with the engraving for those that asked. Engraving is by a very determined young lady in her early twenties named Danae Cresswell. Thanks for looking.











 
i stronly dislike fiberglass insulation but it will be worth it in the long run. 99% of the first floor is wired and about half the fiberglass is up. need to run a copper LP gas line for the heater and the drywall can be done. will be nice to be in the new shop
