KN20 Large Honesuki (garasuki)

This is a larger version of the KN20 honesuki sometimes called a garasuki. The blade is generally a little thicker and longer than a typical honesuki. This one is made from 0.130" AEB-L and features through-tang construction with brass, black paper Micarta and fibre spacers, with the main part of the handle being a synthetic material known as Acrylester Renaissance  #102 . The blade is 175 mm or just shy of 7" long.

West Systems G-flex is used to all the handle pieces together.

Once the stack is all in place the butt is threaded on to the tang screw and a 3/16" mosaic pin is peened into the remaining hole.
Some work on the slack belt really shows how Acrylester is going to turn out. After 400 grit, I took it over to the bench and hand sanded to 1500 grit, followed by some Meguiar's Plast-X plastic polish.

Thanks for looking!

KN20 Honesuki Lefty

My latest little knife, a left handed honesuki (KN20) made from AEB-L and stabilized koa. The bolster is brass, 154CM and black fiber spacer. The construction is through tang meaning the tang is extended all the way through to the butt. The cutting edge is 6" (150 mm). Notice there is no bevel on the right side of the blade?

OSG Nearing Completion

It's been a pretty long time in coming, but the first Open Source Grinder (my DC1) is up and running. Smooth as butter even at 5100 RPM.








































The plans and bill of materials are free on the Sayber OSG web site.
Thanks to everyone who give their input and inspiration.

Got to get back to making knives one of these days!

Sayber Open Source Grinder Project

We Could All Make an Amazing Grinder

One day in February 2017, inspired by the free and cooperative values of open source software; I was thinking that a very good belt grinder could be communally developed and improved in the same way. A sort of Open Source Grinder (OSG) concept.

The goal is to design and make world class 2" x 72" belt grinders and freely distribute the designs. Yup, a crack designer could do that, but ask a few hundred smart knifemakers to refine it, add to it, complete and share their designs.

'standing on the shoulders of giants'



The Ball Starts Rollin'

To start the project I designed a basic frame and base in AutoCAD and DraftSight. DraftSight is free CAD software that almost anyone can learn to use.



These are the basic design requirements

Must work with the following belt sizes:
  • 2" x 60" (50 mm x 1525 mm)
  • 2" x 72" (50 mm x 1828 mm)
  • 2" x 78.75" (50 mm x 2000 mm)
  • Direct drive
  • Three phase 56C/143TC motor
  • Variable frequency drive
  • Horizontal or vertical operation
  • Forward and reverse
  • Standard 1.5" square tool arm
  • Flat platen
  • 4" drive wheel
  • 12" contact wheel
  • Universally adjustable work rest
and finally...

NO WELDING REQUIRED!


When the unit is up and running I will be posting the CAD files, so good folks can make their own.

In the spirit of open source software, I will be hosting all submitted files with changes, improvements, modifications and attachments. 

The bill of materials, assembly instructions, CAD files, wiring diagrams and testing and alignment procedures will be coming to http://sayberOSG.com/




I will keep you updated here as the development and testing goes on.

Looking for volunteers. What can you do to help?


Cheers,

Dan
