[Woodcarver] Koch Sharpening

[Robert Muller Jr]

Thanks Maura, I had a chance to use one at the first NEWR. Andy Fairchock
was there with his. He was a distributor of the Koch system, not sure about
that now. But I still remember how well it sharpened and the fact that it
did not heat up the tool. I plan on fabricating a system. I have a motor and
shaft, It is supposed to turn at around 1700 rpm. Standard motors turn at
1750 rpm. 

 

I would like to see what you are using. I am also looking forward to your
class. See you in July.

I do not have the full motorized system but I do use Koch wheels and Koch
paste.  I have tried a lot of other wheels, and quite honestly they are the
best I have ever used.  Nora Hall, the Master carver, originally from
holland and her company sells presharpened dastra tools and they use the
Koch wheels and paste exclusively.  I used to sell a lot of videos for her
and they gave me a couple of the wheels and the paste at a dirt cheap price
as a top sellers bonus and let me tell you, I would gladly pay 4 or 5 times
the price without blinking. They are really that good.  The wheels are made
of a special compressed fiber. I haven't figured out what it is, its not
felt and its not fiberglass, but something in between. When you use the
wheels in combo with the paste, the paste liquefies on the tool and keeps it
from burning.  I use my home-built system to sharpen all of my students
tools and I have easily sharpened 300-500 tools just in the last year and
there is really not much noticeable wear.  Let me also say that I use these
wheels on a regular grinder set up, turning at full speed and still have
never burnt a tool.  The wheels themselves are quite pricey at about $45
each and if you want to save some dough, make your own system, put a long
spindle on both sides and put a red and blue on one side and a green and
yellow on the other side. Also throw a few cotton wheels on the ends. get
the paste, dedicate on wheel for straight edges, another for gouges, and
leave the other two for honing and the cotton wheels for polishing.  You
will have to figure out the colors and the different grits.  I use yellow
and green.  I really love it and don't think you'll be disappointed.
