Here's that double grinder again

Scary! It looks like a baseball pitching machine...for knives.

ETA after seeing the video It looks safe

A nicely refined version of either of these machines, using 2 X 72 belts would be the cats arse! It could even be designed to flat grind.
I'm suprised that one of you fabricator-types hasn't built one yet.
 
Bill, I was checking out a video of either the Wusthof or Zwilling/Henckels plant and that have huge robotic flat grinders that not only do the finish grind of the drop forged knives, but also put the final satin machine finish on them in a few seconds.

Only 1000 bucks for a one day training session.What a sweet guy.:rolleyes:After you fork over the 4k.:D
 
it's funny how many cry "it's so scary/unsafe/ridiculous" when they have used these machines in industry for a LONG time.
 
I'm suprised they haven't been in common use in the custom knifemaking industry. It seems a properly made double grinder could be done fairly easily.
Yes, it would cost more than twice as much as a regular grinder-but it certainly could speed things up.
 
Am I missing something here? Is there any reason why a maker who has two GIB's or KMG's can't just turn the two grinders face to face and synchronize the speeds?

I think the key is to make the wheels turn in the direction that is pushing the blade out, rather than the other direction which would tend to pull them in.
 
Doesnt look like a tough build, but i bet he sells you his diamond impgregnated rubberized grinder belts. But hey to each his own, i think his descriptions of the time it takes to do a first rate hollow is a bit exaggerated, there are alot of grinders out there that have multiple work stations at that price point, 1000 for training is way off!!

Well if that is not obvious to someone then it's only natural selection at work! ;)

So tempted to build one myself. :(
