On-line class Edge re-profile/convex your Busse.

With all this wet hand grinding and stroking I'm not sure I'm going to last until my girlfriend gets here tonight :rolleyes:
 
Great instructions so far. :thumbup:

What angle would you recommend I aim for on the initial pass? Again, I'm looking for the toughest convex edge I can get that will still push cut paper and shave hair off my arm. As far as I can tell, your guide picture on page 6 is about a 30-35% total angle.

Hopefully the rest of my sharpening gear will be here tomorrow and I can get started.

As soon as I make some positive progress I'll post here.
 
Great pics.
How much do you wet the stone?
I will also be starting tomorrow, i think i will start on my Howling rat.
 
how do you wet and clean the stone? Should I have a tray underneath?

Tomorrow for me too. Gonna be a busy day. I got the diamond stone in the mail today.

Good and wet... I keep a glass by my bench. I just poor a little water on the stone... That is why you have a rag handy to mop up the excess.

EXCELLENT!!!! I have been waiting for someone to ask that!

Ok here is the answer..... WHO CARES!! Thats right! It does not really matter. If you wanted and had the time you could lay the blade flat on the stone and just use the primary grind as a guide!

What we are doing now is cutting a relief grind behind the edge to thin out the edge. We can then thicken the edge some when we move to the sand paper. Err on the side of thinness and if the work you do seems to roll the edge excessively then thicken it back up by convexing on sand paper at a slightly greater angle.

Most of you guys are going to stop to soon and not knock that edge back far enough. So get in there and cut a good new thin bevel and make sure you go to a burr on each side.

After I see some people have caught up we can talk about the next step which is going to a finer stone for just a few mins to get the BIG gouges out from the XXcourse stone. Then its off to the sand paper where we abandon all pretext of angles and measurements and move into the exciting realm of edge ART! LOL!

Is anybody gettng winded yet!?! Woot!! Talk it up gents!! Lets see some pictures!!
 
Winded yet??? I'm still waiting for my stuff! :grumpy: ...But I'm still reading along. :thumbup::thumbup: :D
 
Well i am trying to do it now on my howling rat until my NO-e arrives. Pics will be posted soon
 
My gear didn't arrive today. :grumpy: Looks like I won't be able to start until Monday or Tuesday.

Thanks for the answer on the angle.
 
I would like to see the technique of sharpening. I can do a straight portion fine, but the belly and tip is confusing to keep the same angle. if anyone has a short video clip showing the motion it would be a big help.
 
I have it a try today and I think I did a fair job.
A look at my set up

And the blade before with a sharpie on it.

And what my Howling rat looks like now.

Well The xx course stone removes metal pretty fast. It did not take me to long to get to the last picture, I would say about 5-8 min per side. I found the hardest part was trying to thin down the edge toward the tip. Also this was the first time that I have used bench stones to sharpen a blade and over all I think it went fairly well.

on a side note, i need to get better with my picture taking skills. Please forgive the blurriness.

I am gonna bring the little woman in here to take a series of pictures showing the motion... Best I can do. I could take a 15 second video clip but I have no way to post it here. Maybe somebody could help with that?

Oh yeah.... What I show will just be how I have learned to do it...there will no doubt be a uproar about it being the wrong way. But results speak for themselves.

Standby

A little hard to tell from the focus but it looks good like you have a nice bevel formed all along the edge and those things do get thick out at the front don't they? Did you notice you had to lift the handle a LOT to get the bevel to look even out by the tip? This means that you have a blunter bevel out by the tip. This is OK if that is the result you want. Good job man.

The next step is just to refine that course edge on a smoother stone. Keep going until there are no scratches left from the course stone and anew finer burr has formed from both sides... You did feel for a burr all along the edge right?
 
yep by the tip i had to lift the hand "alot". I still think i want to try and thin it down more by the tip.

I did feel the bur along the edge but toward the tip it became harder to feel.
 
I decide to work on a Basic 3 user that I want to keep asysemmitric. When I got it the side you would strop (the flatter side had been stropped or sand papered so much that there was no edge grind left on the other side of the knife.:eek: It had gone beyond asysemmitric to what Cobalt was calling a bull nose, and it was not sharp.

I had fixed it a few months ago so that it was a good user but now I decided to go all the way and really fix the edge.
