I just received my new disc grinder work rest from Rob (super quick shipping BTW) and installed it this afternoon. It probably didn't take more than about 30min from un-box to start up with tweaks, etc.

As expected it's Beaumont beefy and was an easy set up that went as smooth as silk for me.

Here's some shots of the rig...

1 Deg Beveled Disc...

As you may have noticed I'm also using a Nielson quick change disc system that sticks out a bit further than a standard disc set up does. I was worried about this but have no fear the work rest works perfect with it and in fact there's plenty of extra room to spare.

Here's the workrest fully extended as far as it will go and still be held firm....plenty of room with the quick change plate installed and even with a rubber backing pad as well...

So now I need to throw some sparks. Thanks for making these Rob, it's just what I've been looking for.

Thanks Dave,
Ive been using sheets with the glue and trim method, but the paper just doesnt wear like the Blade would Im thinking!

Been watching your progress on the kitchen knife forum. GREAT work! Are you doing all your grinding post HT?

God Bless

Dave that new rest looks great. This is one tool I have been seriously thinking about adding to my toy box, I mean tool box. :D

Do you have and use a belt sander in conjunction with this? or is this your main grinder?

I had hoped to use the disc for grinding blades but for kitchen knives it's not happening. I could see maybe paring knives but not the big boys. It's remarkable the level of finish you can get at coarser grits though - very promising.

The disc is used for tapering tangs and woodworking.

I use a 2x48 Coote to grind knives. Crazy? yeah! But this is what I had been using for my sharpening & repair work for all those years and I got used to the configuration of grinding on a horizontal platen with the belt running away from me which is even more crazy as I grind blind, mostly by feel - fun stuff!

Knice! Thanks for the info. I still want one! I do alot of 3 to 5 inch blades and can see that this may be a great way to finalize the grind and clean up B4 hand sanding. :)And it just looks cool! that has to account fo something! lol :)

God Bless

Hey Randy, You need one! Works really quick on the flat riccaso sections. Ive yet to master the bevels at the plunge but thats partly due to my inferior work rest being in the way.

Using the 1 deg platen, can you not do large blades?

OK I've had this thing for a little bit now and would like to update my thoughts on it....


1. It's greatest asset (IMO) is the ability to be removed quickly to change up the discs. Using the quick change Nielson system works great with this rig.

2. It really should come with a miter slot. I find myself wanting a miter gauge with this set up far too often. I would have paid extra if this was offered.

3. BIG GRIPE> The table is not flat - not even close. My table is buckled up where the pipe was welded onto the bottom and then there's divets where the welds are plus the corners are all low. I've been working on fixing this for too many hours to count (using two different disc sanders as well as a reference plate/sandpaper) and I'm still only 80% there because this table is TOUGH.

My suggestion would be to machine both sides of the table flat and then bolt some kind of support for the pipe/pivot tube to attach instead of welding them together and having the table moving out of square. I realize that this would cost more but I'd pay it without question because what I have is a little more than difficult to work with.

Too bad the the table is warped. Have you contacted Rob about this? I am amazed at hoe much of the KMG is drilled/tapped/bolted together. I think the only thing I noticed that was welded was the idler wheel/tracking adjustment bracket.
I'm sure he would want to know to make it right.

Dave, I bought the same set up a few weeks ago from Wayne and have been having a blast with it. I do not have the tool rest though, and after reading your last post will wait until they are improved upon. Yesterday I just finished a 10" sabatier-shaped blade on mine. My bevels are far better than any I got with my 2 x 72 grizzly grinder. Plus, I really like the VFD.

UPDATE

I've given up on trying to get the workrest flat. I got most of it fixed, well the sections I use most anyway.

FWIW, I know another knifemaker who has the same workrest (bought within days of my own purchase) that says that his rest is perfectly flat & square. Maybe I just got unlucky.

Again, as PT Doc said, call Rob.
I have worked up a work rest and will be checking it out with my lazer cutter to figure out how much is is going to cost. I'll let you all know when I get it all figured out within the next week or two.

Thanks for the feedback Dave!! Let me know I we can help.

We have shipped a good number of these and have recieved all positive feedbacks so far.

In regards to the miter slot...I thought about this only for a second and felt that a better solution for miters would be to clamp a fence onto the work rest table. You would use a small protractor to set it at the angel needed....it could be a small block, or any sort of straight edge clamped with a small C-Clamp, welders clamps...vice grips...anything. For me, I didn't want a slot on the table...gather grit and dust...and mainly being an empty groove under the work piece.

See how I do this on the KMG in this video clip:

http://youtu.be/BYllaxuzMk0

fast forward to around the 2:00 mark. I just clamp a block on the work rest set at the desired angle. For even quicker miters.....do clamp anything...just use the protractor against the back edge of the work rest....same as you might use a slot. You are only limited by your imagination as to how you might accomplish this...with the speed and accuracy required for your specific application.

"Flat" is a relative term such that it may mean something different to each person. "Warped" to one guy....might be considered "perfectly flat" to another guy. We understand this and always have an open door in regards to customer service, returns, refunds etc. We always want you to have tools that work and function at standards that meet your expectations. If we can't do that...we are always glad to accept a return for refund.

Untill today, we didn't know that your standards have not been met...we will be glad to help.

Thanks again!
