Again.

In YouTube " Demonstrating Tormek's Centering Knife Jigs KJ-45 & KJ-140 | Part 16 " at 5:50 min. the reason for unequal bevels is explained very good.

Hello Merlin,
for a start I would watch in YouTube "Common Tormek mistakes in knife sharpening" by Knife Grinders Australia and the "Tormek Live Sharpening Classes".

Have fun!

There is a description in the forum explaining the problem with the SVM jigs:
https://forum.tormek.com/index.php?topic=2962.0

My SVM-45 jigs have an offset of 1,25 mm, ideal for knives of 2,5 mm thickness at the clamping area.

Tanti saluti dalla Germania

The buffer Vadim (RIP) uses in his YouTube video "Our new setup for Commercial Sharpening - 22 knives per hour" is a Bernardo DS200S with 2850 rpm.

Quote from: RickKrung on May 16, 2023, 03:53:38 PMHave you searched the forum for previous discussions on microscopes.  There has been a fair bit of discussion.  Also, on the BESS Exchange.

I've tried quite a variety, up to one USB unit costing $1200.  The best, most versatile, most informative and cheapest has been the Kingmas 60X hand microscope.  Do a search on "Kingmas" to read posts on this question from many forum users. I have three or four of these around my shop and use it for any number of task.  It is also the only magnifier for getting out extremely tiny slivers.

I also use a tiny microscope like yours to check the edge. Perfect for this job!

Quote from: Sir Amwell on May 14, 2023, 10:22:06 PMThanks Drilon. Just a query, what angle on the felt wheel?
17,5 degrees for the Victorinox knives.

With the following protocol I get 2-digit BESS readings with my Victorinox (Swibo) knives:

Setting the edge 15 degrees/side on CBN 1000.
Honing on Tormek leather wheel loaded with 5 µm diamond paste at 15 degrees/side.
Three passes each side on the rock hard felt (density 0,65 g/cm3
    wheel loaded with monocrystallin 1 µm diamonds.
Final pass on chromium oxide bonded with linseed oil varnish on the leather wheel.

Typical readings 60 to 80 BESS.

When I started this protocol I used a felt wheel with 90 gcm-1. Never reached <120 BESS.

With the paper wheels I got results with very high variation in BESS values.

All these steps I learned from Vadim (RIP).

Best regards,
Drilon

Hello Jeff, the booklet "Knife deburring" of Dr. Vadim Kraichuk (RIP) helps a lot to understand what's happening when you sharpen a knife. You can get it at Amazon.

Your BESS readings are very good in my opinion. The reason to reach under 100 BESS is, that it indicates the the root of the burr had been removed and you get a long lasting sharpness.

Best regards,
Drilon

I got the diamond powder from China via aliexpress.com. In Germany it's de.aliexpress.com.

The price for 100 Karat = 20 gramms ist around 9 Euro/US$. It will last for years! The delivery time to Germany was around 20 days. But google in your country for diamond (polishing) powder. May be there is a local source.

In China the sizes are classified in W-numbers. See the list attached.

Good sprays you find in the drugstores.

Hope this helps!

Best regards,
Drilon

Ells, I had this effect also. The reason was that I sprayed far too much diamond particles on the felt. After some time (about 10 knives) the dust disappeared.

I made my own spray, purchased diamond powder and mixed it with ethanol. Before spraying it you must shake it very well as this mixture settles very fast (wootz mentioned it clearly).

Hope it helps!

It's hard to believe, but it's been a year now since Vadim Kraichuk (wootz) left us. We owe him a lot for his studies and ideas. RIP
