Stabilized Maple Burl Scales

I was lucky enough to pick up some Cactus Juice from a Canadian source (my friend John from Canadian Artisan) which didn't kill me on shipping. I had not yet tried Cactus Juice yet, but had worked with Stick Fast stabilizing resin in past stabilization projects and was quite happy with the results.


The wood is from a friend's back yard. I used a temporary fence on my Porta-Band to slice the scales out.




















Although the relative humidity here is quite low, I took an extra step to really dry out the wood. Into the toaster oven for the day at 50 to 100°C to reduce any moisture in the wood before going in the vacuum chamber.






Working the vacuum in the resin solution.











Here's the results of two amazing sets. Once they are whetted they really pop. (Click for a larger image.)

KN44 Nitro-V Full Tang Chef Knife - The Hollowing

KN44 Nitro-V Full Tang Chef Knife - The Hollowing

The last knife I made featured a slight concave on the right side to aid in slicing and releasing wet foods. As a next step I wanted to make a grind that has opposing concave grinds that look more or less like this:


This is looking from the rear. On the left side of the blade I used a 12" contact wheel and on the right side of the blade I used a smaller 10" contact wheel. Ideally a 6" or 8" wheel would be better on the right side scoop. However, sometimes one has to make do.

I learned that the 10" contact wheel I made for my older BG-272 fits into my newer Sayber grinder. Coincidence?














Here you can see the hollow starting to take shape.














The view from the back. It's a pretty good match to what I hand in mind.












West meets East in a sort of kitchen Bowie with an asymmetrical Japanese style grind. It should be good for a tester.


I have to say, that this one bit me in the thumb. It's incredibly sharp.

Toobinator 2 x 72 Belt Grinder for Knifemakers

Toobinator 2 x 72 Belt Grinder for Knifemakers


I wanted to give a shout out to a friend who is making some high quality 2" x 72" belt grinders based on my original BG-272 design. These machines are very well made and come properly welded, drilled and tapped, powder coated with platen, wheels and a 1.5 horsepower single phase motor. Just mount and slap a belt on and start grinding.


Check out the Toobinator on eBay.

KN41-2 Hidden Tang in Nitro-V Blue Curly Maple and Brass

Hidden Tang 9" Chef's Knife in Nitro-V

This is another KN41 in the through tang handle configuration which I extended the blade by nearly an inch. It features are clipped tip shape and 9" cutting edge. The handle is made from brass and blue dyed curly maple stabilized at Woodstabilizer.com. The rear bolster is threaded on to a stainless steel tang screw that is fitted into the knife tang during assembly. The handle is 4.25" long with another 1/2" at the neck for pinch gripping.












The rear bolster is angled to reduce some of the back-end weight and bring the balance forward around the pinch-grip position.








The blade is symmetrical ground from 0.09" at the spine to 0.015" at the heel with a 17° cutting edge. 











Sometimes one cannot be sure what the inside of a block of wood will reveal when working it down from the outside. This is the beauty of wood.

AEB-L Chef's Knife in Acrylester and Brass

This is another 8" chef knife made from AEB-L 3/32" stock that is from the KN41 full tang pattern which I will post soon. The blade is symmetrical flat ground down to 0.015" and then a 17° (per side) cutting edge was formed.

The bolsters are brass and the scales are Blue and White Acrylester #36 from Wood and Acrylic Supply.


The pins are 3/16" brass and a center mosaic.









Coming up is another chef in Nitro-V.

Working on a Chef's Knife CPMS35VN

Finally the weather has warmed and some steel that has been sitting since last year is taking shape.

I heat treated and ground this blade in autumn 2017 and did some hand sanding indoors while winter held its grip on us northerners.






With all the handle components lined up and cleaned it was time to get the G-flex on. This handle is a plugged version of the a hidden tang. The plug is a small piece of stabilized maple burl.






After the epoxy is set the handle is squared up and shaped with a 60 grit belt.






For rounding out the handle I like using the slack section of the belt and kind of rotate the handle to give it the oval shape that fits well in the hand.





Here I am working on sanding the back end. You can see plug there.






Doing some more wet sanding on the bench and epoxy clean up.























Thanks for looking!

20 Ton Forging Press Part 2: Pneumatics

More on the 20 Ton Forging Press

I added another page on the forging detailing the controls I used and the couplers to actuate the jack release valve with the pneumatic cylinder.


See the DIY 20 Ton Forging Press: Part 2- Pneumatic Controls page.


I hope to have part 3 on making the dies up soon.

Update on the DG-9 Disc Grinder

Looking like it's ready to roll. Time to get her out of the kitchen and mounted to the bench.


There are a couple of step-by-steps that I did on wiring the forward/reverse switch and the main power switch on the KBAC-27D.

There will be a few pages on making the frame coming up soon.

Making of the DG-9 9" Disc Grinder (coming soon!)

It's been a long few wintry month and a half and cabin fever seems to be getting the best of me. While staring out the window at the snow, I started day dreaming about making a 9" disc grinder.

Soon parts started to arrive...Hopefully spring will too.


The KBAC-27D is a Variable Frequency Drive (VFD) that can control the speed and rotation of a three phase motor up to 2 horsepower, rated 208/230 VAC. This VFD has an advantage when used in the gritty environment of a belt grinder because it's sealed up and dust isn't allowed to get inside.






The motor is an Ironhorse 1.5 horsepower 4 pole (1725 RPM) three phase unit from Automation Direct. Similar to the one I used in my Sayber OSG but this one runs at half the speed.







The 9" disc is machined from a solid aluminum billet. I ordered this from USAKnifemaker.com. It is a 9" disc that has a 1° bevel on the face, so really it's a tiny bit like a cone. This bevel is to help prevent the knife that you are grinding from catching the opposite side of the disc and flinging it upwards. 




Along with the basic frame details, I will be putting up some posts on how to wire the KBAC for forward and reverse and installing the main power switch. 

Stay tuned,

Dan

Got a New Set of Wheels!

New Wheels for Another Belt Grinder Project


In advance of my third grinder project I ordered up some of Oregon Blade Maker's 4 piece aluminum wheel set with a drive wheel having a 5/8" bore.

It should be noted that not all motors can use this drive wheel. Only motors with 5/8" keyed shafts can use this set. Fortunately, Oregon Blade Maker offers a set for 7/8" and 24 mm motor shafts. See the links below for the different bore sizes




The parcel came very well packaged. These made it half way to the North Pole!







Each wheel was individually wrapped in bubble wrap.



The machining on these wheels is very good. All the bearings are sealed and take a 1/2 bolt to mount.


This set has a drive wheel with a 5/8" bore and has a 3/16" keyway. This will work for a NEMA 56 frame motor. NOTE: if your motor is has a different size shaft, say 7/8" then be sure to order the correct set.







The 4" drive wheel and 3" tracking wheel are crowned meaning they have an arch to the part of the wheel where the belt will run.


This is where you get the long 1/8" hex wrench down to lock the setscrew into the keystock



And I got this cool sticker to go on my machine!
If you are looking to buy a wheel set these are the one's I recommend:

NEMA 56 frame motors have a 5/8" shaft then look at the 5/8" bore four piece aluminum grinder wheel set

NEMA 143T and 145T motors have a 7/8" shaft then look at the 7/8" bore four piece aluminum grinder wheel set

If you are using stepped pulleys, pillow blocks and shaft is a 3/4", the 3/4" bore drive wheel comes in a set of four wheels. 3/4" bore four piece aluminum grinder wheel set

If you have an IEC motor with a 24 mm shaft, presently only the glass filled nylon drive wheel is available. 24 mm bore drive wheel only. But you can build a set by adding a three piece wheel set to the drive wheel.

Happy grinding!
