What have I been up to? Well, I'll tell you anway.

Awesome Salem!!!

Congrats on cutting out the cigarettes! :thumbup:

Looks like you've got a smoke'n hamon in that blade, and I LOVE the key-hole action you've got going on here. I'm stoked to see this knife come to life Salem! Thanks for sharing. :cool: :thumbup: :)
 
Then with a little tweaking and filing and such, I actually improved it to the point where it would look OK glued up. The block fit in quite firmly.

But, I don't want to have to lean on glue much to fill for me, (especially since I'm not using a black wood) and I think that with what I've learned from the test block, and the fact that I'll be using a much harder block for the actual handle, the fit will be better yet on the final piece. Either that, or I'll be swearing while destroying the block out of the handle...

Some of the best pieces I've seen done this way have no pin through the handle, and while I'm sure those knives are rock solid (done by more experienced makers than me) I will be vertically pinning this handle for added security, like Ron Newton does.

That's some excellent hand fitting.


I think if I did that, I'd want to use some sort of router / pantograph tracer attachment.
 
Salem, if you want a large piece of lignum vitae or a few pounds of nice African blackwood, I'll be happy to donate to the cause of this gorgeous knife.
 
Salem, seems like your PM box is full. You can feel free to email me if you like.
 
This is going to be epic. Greg is sending me some blackwood, which I'd wanted to use all along, but hadn't quite decided to obtain.
Greg also came up with the name for my hyd. press a while back, "Sasquash" which is very PNW. It'll be operational soon, too.
Thanks on both accounts Greg! Gotta love Shoptalk.
 
Just got the Blackwood in. It's heavy, dense, beautiful wood and it frankly amazes me that Greg hooked me up with this generous amount of great material.
I'll be working on the knife again tomorrow, today's welding time in the shop.
 
Pics, or it didn't happen! :p

Just josh'n... I'd rather you get that press welded up than take pictures of unboxing the wood. We'll get to see plenty of pics of the wood when you're shoving it into that key-hole. ;) :)

Heck of a gift Greg! :thumbup: :cool:
 
Here's another installment!

I sanded the faces of the three blackwood blocks. All are nice, but I wanted to see if any had pretty grain. With a 220 finish, I was able to pick one out from the others. I'll show it in a minute.

I figured out what thickness I wanted the slab, adding about .125 to the handle thickness to be able to chamfer the leading edge of the handle piece. I set the rip fence on my bandsaw and went to work. I basically had to friction cut it in little bites, as it's very dense wood and not a new blade.

This is my vintage 12" Duro bandsaw. Got rid of my Craftsman and rebuilt this saw, as it's got a monolithic cast frame that can take tension. It's got a 2 hp Baldor motor on it now!

After roughing the cut face flat, the grain stands out:

The block itself was irregularly cut, so now that I have ripped out a piece with one good flat side, I put it in the mill vise and took the other side down flat to establish a uniform thickness. I did this carefully trimming around the edges first in the correct directions to avoid splintering.

I traced the tang onto the piece, cut it out, and ground closer. I chamfered the leading edge just a bit with a file.

I began the pressing process with the vise. It peeled a nice curl along the tang edges. I believe that's what you want, a sharp steel edge to cut into the wood rather than a dull edge that will cause the opening to be pried open instead. I filed a bit more, and pressed more.

After pressing the piece most of the way through, I took it back out (difficult!) and drilled for the vertical pin with a 1/8" bit.

After scrubbing the tang surface off inside, I mixed up some epoxy and added a few drops of black leather dye. Bingo, black epoxy.

I slathered it all up and pressed the block all the way through. I thought I had taken a pic of the knife glued up, but no... anyway it sits until tomorrow for now.

I looked over at the hot work area and thought to include a snap of my hydraulic press project, welding all done and ready for plumbing.

I shifted gears and went to finish grinding an 11" twist dammy dagger blade, post HT. It's getting a 4" hollow grind on the contact wheel assembly I made just for it. Small diameter hollows are fun to grind! I roughed with 8" and deepened the grinds with the 4" wheel.

A quick couple shots of the wheel. It's just a 4" industrial caster with an iron hub and poly tire. You can get them from Grizzly for like $10. I milled out the grease zerk area to improve balance, and mounted it on a 3/4" bolt using just the original crap needle bearings. Running it on the grinder, I tracked the belt first to one side and rounded the corner of the wheel off with a horseshoe rasp, then did the other side.
It only runs smoothly at lower RPMs since I didn't really balance it, and I'm going to replace the bearings with some better ones soon, but on my VS grinder it works just fine for hollow grinding. Needs a drop or two of low sling (chainsaw bar) oil now and then on the sides.

I did a better job of balancing another caster, and crowned the face off on the lathe, and now it serves as a tracking wheel for my old Olympic Square Wheel. I include the pic to further show that with a 4" caster and a little chutzpah much is possible on the cheap.

A quick shot of the dagger blade in the sanding station- with the 4" radius steel sanding bar I hammer-curved hot out of bar stock over the anvil horn.

And that's it for the night! Stay tuned for further adventures. Thanks for reading this thread everyone.
 
Here's another installment!

I am officially nominating this for the Best Post on the Internet Award.

A bandsaw with a 2HP motor, Bob Marley, a wicked-nice dagger grind, so many great tips, so many awesome photos, and even has the word "chutzpah".

Bravo, Salem. :D
 
Great update Salem!

That little bandsaw looks like a beast. :cool:

That's some killer Blackwood... one of my favorite woods!

I love that dagger blade. Killer grind Salem!

FWIW- I used to do a lot of hollow ground daggers, and found I could keep the center line sharpest by sanding with a round block that was a bit smaller than the diameter of the contact wheel, until doing the final pulls with the finishing grit.
 
It's a bottle capper that requires great finesse!:eek:
Thanks guys for the comments. Nick, that's a good tip! Luckily the sanding bar is just a little smaller than the grind. I like to have a little leeway anyway, and it's easier if they don't have come out perfect.
 
I am not sure if it was intentional but the way you oriented the wood grain to be flat sawn will look really good when it is finished. Sometimes the blackwood will show a flash of color when cut that way. The grain looks cool too.

Kudos to tryppyr for donating the wood.
