Update!

I created the original razor again.

My process:
I leaved 1.5 mm thikness of the edge.
soaking: 805C / 1480F, 8 min.
quenching oil: 55C 20 sec
tempering: after cooling to room...

Thank you very much!

It seems to succeed. I will refine the edge, but everything looks good.

This is worked for me:
I leaved 1.5 mm thikness of the edge.
soaking: 805C / 1480F, 8 min.
quenching oil: 50-60C / 130F,...

Thank you so much, it is very useful for me. But just now it was broken the thermocouple in the furnace. :( Yesterday ordered a new one.

Sorry I misunderstood this. I do not use such a compound. It sounds good. How much influence the standard HT process? What brand would you recommend?

What do you mean preheatin? The furnace,...

Is there any need to normalise if you're not forging?

Thanks!

Yes, sorry. 1/16" = 1,59 mm. For me much more simple to use the Metric system. :)

Than I will grind it about 1.5 - 2 mm. I jus read that somebody is leaving the total thickness before the HT: ~6...

An other guy's recipe. Sorry but I dont rememeber hes name, I copied from SRP.

"Heat to 1450 F and hold for 15 minutes. This is called soaking, and it allows the carbon to dissolve back into the...

I will do this and I will see.

In addition I will make a simple razor fort test.

My plan for the HT:

I leave at least 1 mm (3/8") thikness of the edge.

I am sorry about it.

I think they were right. I suspect to the thinly grind edge (0.8 mm) before the HT. Because the situation has improved, that took off the edge but not enough.

Yest. It is perfect, 16° with one...

Mike,

thank you for thet details. I will ask for more things soon.

Bad news: retempered, regrinded, repolished, rehoned and reshaved but it does not work. :( The edge is too sensitive, wear out...

After the polish I use Renaissance Wax.

Thank you so much!


Many of the makers wrote about the two cycle of tempering. Why, if one cycle is necessary?

Thanks! I hope it will be a good shaver too. :)

Thank you guys! I preheted and stablized the oven before I put the blade.

The result:

This color is also given a new design idea. :)

Thank you, Mike!

One more question, maybe stubid. :) I completed the re-tempering. This procedure on 425 degrees does not cause any trauma in the thin edge like the over-polishing?

No, just the honing is too hard and the steel is very rigid. The good news, I could shave with it. The result is 8/10. The edge is almost undamaged. :)
One more round and I get to the finish, I...

Thanks, Scott!

Recently talked to my wife about it (She speaks better English than me) how good you that the whole World can understand you in the native language. :)



Thanks, I see. The 25 degress is...

Sorry for my poor english. :) I meaned if you feel the end result is too hard maybe you should re-tempering the blade. You have been doing this routine, but when you test it.

Thanks, Charlie! This is similar to mine. And if you do a re-tempering, you also need twice an hour or once an hour is quite enough?

During the honing process I see if there are any problem: the feeling, lights on the edge, hand shaving..etc.

It seems You are right. I should have let a bit more thickness on the blade. I sanded from the edge a few and it is almost good.

It seems very stark I would like to re-tempering the blade. In this...
