Knife making adventures... part 7 - Drilling tang holes.

This post will be short.

I had to drill few holes in my gyuto tang. I have marked holes with center punch.


I remembered that previosly, drilling holes was a nighmare for me. Now I decided to use some kind of lubricant. There are special drilling fluids out there, but instead of buying something, I have used camelia oil.

I was really surprised to see that it's working.


And it's working well:D

Knife making adventures... part 6 - Initial grinding

Hello there:D

Unfortunately I must abandon my neck knives project and focus only on kitchen knives. As I have mentioned before, I am running out of time, because I must finish my kitchen knives till May. Reason for that is, that one of them knives will be a gift for my friend and second one is that I am going to Denmark to my fourth JapaneseNaturalStones.com annual gathering.

Before heat treating I wanted to grind my blanks a little bit. I started free hand and at the beginning it goes well.


I had funny (for me ) situation. My girlfriend was waiting for parcel from Hermes. They said that they have tried to deliver our parcel twice and now it was last chance to get it. Just watch video above starting from 7:00. I thought that I have seen something in front of my window. I've turned of my grinder and noticed that somebody is calling me. So I quickly jump out from my flat to open the door. There was older lady with my parcel. What did she think when she saw me like that?


It was even more odd, because camera was attached to my chest and I had big knife half painted in red:D hahaha. I am pretty sure that they will never deliver my parcel again.

Grinding full tang knife was easy. The other one, big gyuto, was hard to grind because of the tang. I couldn't hold it so I have attached it to the piece of wood.



And grinder it this way.



I have burned tip a little bit.


Then my blank felt on the ground and I bent the tip:





I straightened it with hammer. I do not care about, because I will grind it away after HT.

Now to clean blades I used my C powder 80 grit mixed with J-nat Red Aoto mud.

Knife making adventures... part 5 - Distal taper

Hello there.

I spent whole morning on making distal taper on my kitchen knives. I was very happy that I got new belts from John Mol, because it made my life easier, though, it wasn't that easy.

So I started from measuring thickness of my blanks.


Then I've gone to about half of the thickness.


And have used calipers to mark center of the edge.





Also I've marked point where I wanted to check thickness of the blade. It's on the hell, middle of the blade and about 1cm from the tip.


I tried different angles of aproach. I tried to grind distal taper sideways.


...lenghtwise...

And with belt grinder pointed vertically.



So here are my blanks after making distal taper.





Thickness near tip:

New website



I would like to proudly introduce you my new website. It's still under construction, but there is not much left to do. I am very happy with my new gallery. Previously uploading pictures was a nightmare and I had to spend half day to upload few pictures. Now I can upload pictures and video in just a few seconds. Also I would like to introduce you my online store. It's empty at the moment, but in few days, when my website will be finished, I will add few products. Please share my address: www.wabocho.com. Thank you for support and let the sharp knives be with you:D

Knife making adventures... part 4 - Shaping blanks

Ok, so now it's time to put a final shape on my blanks.

To do that I will do what I can on the belt grinder and then I will follow it with files.

My grinding station. Many people would condemn me for what I am doing, but I have no choice. I am using my beltgrinder in the bathroom since two years. It is easy for me to take everything out of the bathroom, setup my grinder and clean after job.

My belt grinder:
And blanks before shaping.

Of course using PPE is crucial


 So I started from shaping spine on the 40 grit belt.




 And then rest of the curves.


 I have noticed that doing that on the disc sander is way faster.


And here is the result of shaping on the grinder.


Later I had to refinish all curves on the handles with files (another gift from my girlfriend).
  
I tried to do that over the sink, but I couldn't mount my vice properly.
 

Then I have tried portable workbench, but it wasn't comfortable as well.



I have mounted vice to the table in my saloon.




After shaping with files I wanted to even out all edges. I've used pillar drill with grinding stone.


And here is the final result.


Not bad so far. My next step is to make distal taper.
