  Powered Sharpener Setup Recommendations
Posted by: blgentry - 12-28-2019, 02:36 PM - Forum: Relevant General Discussion - Replies (37)

I would like a good powered sharpening system.  I currently have a WorkSharp Ken Onion and have sharped several hundred blades with it.  It's a really good machine for the money, but it's "slow" in that it can't really remove metal fast enough to sharpen knives quickly.  On maximum speed, it's also very loud.  

I think what I want is a 1x42 belt sander with variable speed and reversible.  I also want something to make deburring very easy.  Several people have recommended a paper wheel on a bench grinder (buffer).  This has the added advantage of having two wheels, so I can use the other wheel for something like a cotton buffing wheel, which I would use for deburring serrated blades (the serrated side, after having ground the flat side to form a burr).

I would like to be able to see the burr forming as I sharpen.  It seems like a horizontal belt is the best way to do this.  I've occasionally gotten lucky with lighting and been able to see the burr form on the WSKO.  It's really neat to do it this way.  I'd like a setup that's designed to make this happen.

Until recently I thought that sharpening edge leading on a belt was incredibly dangerous.  But over the last week or so I've read a lot of discussion on this that seems to conclude that edge leading sharpening on a belt has a very low probability of grabbing the blade and throwing it.  I'm interested in opinions on this too.  Edge leading would seem to be a better way to reduce burr size to start with so deburring will be easier.

I've looked at the Veil S5 that Steve Bottorf sells, with the adapter plate to let it take the Penn variable speed motor.  But that setup doesn't appear to be truly variable (only goes down to 600 RPM) and it is not reversible.  Maybe reversible isn't important; I'm not sure as I lack experience with real belt grinders.

I've also considered the Kallamazoo 1SM.  I can only seem to find these with a single speed motor included.  Which probably means I need buy my own motor and waste the money on the motor that was already included.

Today I talked to Richard Pope who has made a lot of machines like this.  But he's mainly focusing on scissor sharpening now and his products are mostly out of my price range at > $1000 .

Thanks for any advice for specific machine setups.  Also thoughts on edge leading sharpening, reversible motors, and deburring are all appreciated.

Brian.

  With a Heavy Heart
Posted by: Mike Brubacher - 12-19-2019, 11:41 AM - Forum: Knife Making & Bladesmithing - Replies (16)

With a very heavy heart, I must report to our members a great loss. Our friend and moderator of this forum, Mark Reich, passed unexpectedly yesterday in Belle Fouche, at home. This strikes me as lightning bolt would. My condolences, as well as EOU's, go out to Mark's wife and family. Mark and his wife were guests of mine at the farm and she is as lovely and gracious  as her husband was.

Mark was among my very first customers and that's how our long association began.  Our first meeting over the phone lasted well over an hour.  Beginning with that first call, Mark was never just a customer. Much more than a customer, Mark was always a friend, an adviser, a mentor and a confidant. I,  the BESS Exchange, his friends and family, knife makers and blade smiths everywhere, will suffer his passing greatly and forever.

  How to prevent the edge oxidation?
Posted by: SHARPCO - 12-05-2019, 06:08 AM - Forum: All About Edges - Replies (5)

I think I need something like oil. I've used camellia oil. It's food safe but I found it couldn't prevent edge oxidation well. 

What is the best solution? I'm looking for it can be used on kitchen knives. 

Thank you.

  ID75A and PT50 Series
Posted by: Mike Brubacher - 11-25-2019, 05:00 PM - Forum: Edge Sharpness Testing - No Replies

We get a lot of questions concerning the differences between the ID75A and PT50 Series instruments. In addition to the  ID75A's RS232 communications it's just plain bigger. Here are two units going out today and I took this picture to demonstrate the difference in the packaging sizes.

  Too dull to shave with?
Posted by: grepper - 11-16-2019, 09:27 PM - Forum: Edge Sharpness Testing - Replies (8)

I use disposable razors because they perform reasonably well, last a month or more each and are incredibly inexpensive.  I use nothing special double bladed ones because for no real reason I think they perform better than single blade models.  I bag of a dozen costs less than $10 and I’m good to go for a year or so.  When they get too dull to use they join billions of others to help fill our landfills with plastic crap that will survive there for the next 400 years or more.

I have probably about average beard consistency.  Not like a wire brush but not peach fuzz either.  If I don’t shave for a day it’s very visible and scratchy. 
 
Today one reached the point where I decided it needed replacing with a new one.  I think it has been in use for more than a month.  It was not horribly dull.  It did not grab, yank or tear hair out but required 3 or 4 passes over the same area to get the job done.  In a pinch it could probably have been used for another couple of weeks but I decided its useful life had passed.  Here is a picture of it.


   
 
I’ve often wondered as to the sharpness when I decide one has reached its demise.  I was guessing it would be 300 or so.  This time curiosity got the better of me and I decided to actually measure the sharpness.   I “disassembled” it and removed the two razor bands using a process that resulted in eliminating any possibility of reassembly.

   
 
The little strips of metal are incredibly wimpy, thin and flexible.  An impressive job of design and engineering to make a razor out of them that performs as well as they do.  To perform the measurement I gripped the metal strip with two needle-nosed pliers and grasped the razor band with the jaws maybe 3/16” apart from each other.  This stabilized the blade between the jaws of the pliers enough to perform the measurement. 
 
I took a total of 3 measurements, two on one blade and one on the other.  I was truly surprised by the results.  As I mentioned I was guessing to see something like 300, but instead the measured sharpness with the PT50-B was:
 
65, 75, 75
