I really wish I had a good way of forging shoulders that the handles could sit on, instead of the tang going right into the gouge body.  I might try to make some dies that would work with this, or some kind of guillotine / spring fuller tool.

Be careful with O1, thin sections will air harden.

Yeah, it can crack easy if worked too cold.  I've made a couple knives from it without trouble before, being careful about the heat.

I have some 1/8"x 1.5" 1080 (also 1/8x2" O1). I think I'll try this this weekend. I'll have to get creative for the sweep though since I don't have a swage. Maybe use a stump?

If you have some round bar stock, you could use that to shape the concave/inside flute while hammering around the convex outside.  Maybe even a tin can filled with plaster would work okay for a round fuller?

These look great. What was your starting stock size?

Thanks, I started with 1 1/4" wide 1/8" (or maybe 3/16"... can't remember) thick 1080 stock from Kelly Cupples.  

Yeah, it ended up as a lot of steel... almost bit off more than I could chew.  Rounding the corners a bit before twisting would have helped, I'll do that next time.  I'm going for low layer count more for interesting patterns than historical accuracy.  

This weekend I worked on forging my first full-scale pattern welded damascus billet.  I've previously done one miniature damascus test with a bandsaw blade and pallet strapping and it turned out okay.  This time I used 1.25" wide 1080 and 15n20 pieces tack welded into an 8 layer billet after a lot of grinding to make things square and shiny.  I welded on a handle and heated it to about 2325 deg F in the forge until uniform temperature.  I did fluxless forge welding for the first time and it seems to have worked perfectly so far, I didn't see any separation while drawing later.  After drawing out the bar to about 1" square I twisted it (took a few heats... 1" is pretty thick for my small twisting wrench).  After I took the neat picture below, I forged it nearly square again.  That's all I was able to do with my arm power for the time being, I don't have a power hammer or press so this is all hand hammered.  Not sure what to make with it yet, maybe an axe or kitchen knife.

Those look great!  What was your procedure for grinding the convex back part of the gouge? They look very symmetric, and I wonder if you had some kind of jig to do that?

-- Dave

Thanks.  No jig, I just used a flat stationary 6x48 belt sander and pivoted the gouges while grinding.  As a finishing step, I briefly used the slack of the belt to polish things up.

I like them!  Did you hot fit the tangs?

Thanks.  I didn't hot fit them, I drilled out the tang holes a bit wider than necessary then used a lot of glue.  Thought about burning the tangs in, but the last time I did that the wood beneath the ferule shrunk and the CA glue burned out, making the ferrule loose.  I'll try using a good epoxy next time instead.  

Those are both clever ideas, thanks.

Nice!!! ....Did you make them with the swage block that I almost bought??? 

You know it.  That thing works great:

Thanks for the inspiration.  I use In-Channel gouges in my work, mostly Buck Brothers Off Set gouges, I have had a hard time finding decent used 3/8" off set gouges in various sweeps.  So looking at your post I just had an ah ha moment.... I'm a blacksmith (sort of), I can make this stuff. I now have something else to add to the list, and 1080 does not scare me ether.

They were pretty simple to rough forge thanks to the swage block.  Drawing out the tangs was the hardest part.  If I cut the tangs instead, I could really crank these things out.

Bob,

Check out Alexander Weygers book The Complete Modern Blacksmith.

It has great instructions on making that kind of tool. 

He was a professional wood sculptor and made his own tools, especially gouges.

What sweep are those gouges? (London Pattern number).

SLAG.

That's a good reference, thanks.  Mystery sweeps, from three different positions on the swage block.  I could try to work out their radii, but it would take some math.  

I forged this set of incanal wood carving gouges from 1080 steel.  The handles are walnut and copper.  

Really great work, I love these things.  

As a programmer and hobby blacksmith, I find this project really interesting.  I don't have much to add, the previous replies sum it up really well.  Would this be in 3D, and would you use a mesh deformation physics simulation package?  

J.W.S., where did you get that chunk of steel for so cheap?  Ordering a piece like that online would be $300 or more.  

I have almost the same anvil (a mere 129 lbs, though).  Looks like it's in great shape.  How will you secure it down?  I haven't secured mine yet, it needs it bad.  

Really great work, love the welded edge and clean lines.  

Thanks everyone.  I'm making a display/holder for my drawknives now to mount on my french cleat wall in the shop.  

Why did this get moved?  This is a finished project by a member, so doesn't it belong in member projects?

We should rename this thread the "Eye Candy" thread. Beautiful draw knives Bob and what a hand saw!

Frosty The Lucky.

Thanks Frosty.  The hand saw is so pretty it's hard to use in case I scratch it.  I'll have to come up with a good project for it soon.  It's made for cutting tenons in medium sized boards.  

I finished a second chain damascus drawknife.  It has a 1080 steel backer with redheart and copper handles.  I traded the bigger one to a friend (Brian of BearKat Wood) who made me an incredible woodworking hand saw in exchange.

Looks great! I love it! Mind sharing how you went about heat treating it?

                                                                                                                             Littleblacksmith 

                                          

Thanks.  The chain is only on the bevel face.  The flat back (and thus the cutting edge) is an old file, so it's likely a water-hardening high carbon steel.  But I was scared to water quench it, especially with the chain attached.  So I preheated my oil a little for a slightly better quench.  I heated the whole drawknife up until it wouldn't stick to a magnet, then quenched in the preheated oil.  It passed the file test well after that, so I tempered it at about 425 deg F in the kitchen oven, then drew a softer temper on the tangs using the opening of the forge.  

Thanks.  Fortunately I have one more chain and some 1080 stock that will make another good drawknife for myself.  But I kind of like the recycled old file with the teeth still visible.  Might have to find some more.  

And it's done! 

I attached the finished pics below, too.  

I finished the chain damascus drawknife I've been working on.  Forged from a bicycle chain and an old file.  Redheart handles with copper ferrules.  I managed to crack one of them when inserting the tang, dang it.  Filled with CA glue and sawdust, then sanded back... it looks decent, but obviously there.  Still, I'm very happy with how this came out.  I'm trading it with a buddy who is making me a fancy custom hand saw.  It'll be hard to let it go, might have to make another for myself.

Beautiful piece. What did you use for flux? 

Thanks.  I used lots of mule team borax.  

Here it is after heat treatment and polishing, before and after the etch.
