So, here's what I've learned about grinders recently, which should be informative for the general new-to-grinders population at large:

1) Knifemakers don't get rid of grinders, so don't ask or you'll insult them!:footinmou
2) There are a lot of options, but the team favorites for BFC seems to be the KMG, Coote and Grizzly.

KMG
The KMG is the king, without a doubt, for two apparent reasons: excellent quality and versatility. Take a look at the KMG site and you'll see it's like a Transformer toy! This is the obvious choice for the pros or the hobbyists who never want to have to buy an upgrade machine. The downside is that it is expensive, and the add-ons are pricy, too, but it doesn't seem like there is "empty cost" built into it. In other words, it does a lot more and is better quality than much more expensive machines. The main issue isn't whether it's "too expensive" but rather if the qualities you get in the machine are worth the added expense to you. Very prompt service from Rob Frink, who makes the machines, and there isn't a bad thing to say about KMG anywhere, as far as I could find (although I've been accused of only reading what I want to read, so take that with a grain of salt). The basic KMG setup costs $650 for flat grinding only. To more closely compare apples to apples, to get the flat grind/10" wheel package, you pay $840. You also need to pay $85 or so for shipping, buy a motor and some pulleys and belts to run the motor. You can get this machine "out of the box" for a bit under $1200 (includes motor, pulleys, etc etc).

Grizzly
On the other end of the spectrum is the Grizzly 2x72" grinder. This is all in one unit, and everyone says you have to upgrade to a 10" wheel. The grinder and 10" wheel setup are $478, including $55 or so to ship to wherever you are. This is a very popular machine, but it's what it is. Unlike the KMG, you sacrifice some quality and it isn't a Transformer robot, so you can do basic stuff with it and that's it. According to people here, it is a great value, and many use the machine for "hogging metal" and a lot of the rougher work, then use their KMG or more expensive equipment for other operations. It runs very fast and the motor is hooked right up to the grinder, so it can't be messed with to step it down without quite a bit of modification. Lots of makers got their start on Grizzly machines and say they are pretty good, but that there are better ones out there (like the KMG).

Coote
Coote is the underdog! It floats somewhere between the KMG and Grizzly. American-made, good quality, same basic idea as the Grizzly, but a little more versatile. For $410 you get the 2x72" grinder with a 10" wheel. You can get into other sizes of wheels, add a small wheel attachment for tight radiuses (for $120), etc. Shipping is about $35, according to Norm, the machine's maker. You supply the motor, pulleys, etc. From what I read, the Coote is a great machine, and people generally love the way the small wheel attachment works out. It's a little bit more than the Grizzly, but better made, American made, slightly more versatile and gives you a lot more flexibility to put step pulleys on it to make it do more things more easily. So, around $500 gets you the machine, then you worry about the motor. Maybe you'll spend $100 more or so than the Grizzly, but it seems well worth it.

So, all things equal, if you want cheap and easy, get the Grizzly and you'll be happy. If you want cheap and flexible, get the Coote and your own motor and you'll be happy. If you want the one everyone dreams about, get the KMG and you'll be happy! And, if you compare prices of similarly spec'd grinders, the KMG starts looking cheap, too, so it's all relative.

The KMG is really the machine to try to get into if you think this hobby will grow. I.e. you can start as basic as possible, rig up a motor that works for cheap, etc and if you really find yourself enjoying knifemaking, needing the add-ons, etc, you can grow into it and upgrade motor, wheels, accessories, etc. The Coote has a couple of things you can do (small wheel attachment) and that's about it, and the Grizzly is what it is.

The last thing I've learned is that because no knifemakers sell their tools, if you get into a decent grinder and find you don't want it anymore, you can probably recoup most of what you paid for it by selling it here. You'll lose a bit of $$$ because people would just as soon buy a new one than a slightly underpriced slightly used one, but you probably could unload it pretty easily.
 
Unless you're going to do a lot of large blade hollow grinding, I would say to forget the 10" wheel on the Griz. I bought one and it just turns too fast.

You can get the Griz on sale most of the time for like $275.00.

The KMG is the King at the lower end level, <$2000.00, but there are high end grinders like the Bader III that are hard to beat. I have used a tricked out Wilton that was pretty impressive.
 
The Grizzly is now $355, I think, whereas until January 2005 it was $299, so I think the days of the $275 sale may be long gone, FWIW.
 
Chiro75, I think you nailed it on the grinders. I too think those three are the most often bought grinders. Not everyone can start out putting down mega-bucks for a baderIII or a wilton but they are fine machines when you are ready to up-grade.

One of the positives about the grizz is that you don't have to buy a seperate motor and wire it up. It also has the mandrel on the other side that you can put a sanding tube or a buffing wheel on. If you hit those points already I missed them in my scan of your post.
off to work.
 
I first bought a Sears 4" X 36" and wore it out. Then I got a Jet 2" X 48" and a Delta 1" X 30" and still have the Delta. By the time I got to the Griz, it seemed like fat city.

If I ever get good enough (or rich enough) to justify it to myself, I will probably buy a KMG. The grinder does not the knifemaker make...
 
Rub it in Kit! I like my KMG but would go Bader III also if I had the extra money. I still like the attachement prices.

Steve nailed it. Buy the best you can afford. There are some of us that still make their own grinders and like them just fine thank you.... :D
 
Just outta curiosity, what is it that makes the Bader 3 superior to the KMG?

This is a friendly question, mind you. :) I've had a Bader 2 since I bought it new in 1983. I have battled that beast for years. It had some design flaws that made one machine great and the next cantankerous. I got one that fit my personality...

The design of the Bader3 and the KMG look to incorpaorate many of the same design characteristics with square tool arms, etc. that overcome the problems of the "2".

What makes it better than the KMG. Thanks!
 
What about Hardcore? (The grinders, not porn)

No one has mentioned them. I have one and it is a great machine. A little cumbersom to change attachments but is is the smoothest, quietest grinder i have ever used. Alltho the KMG comes close. I also have owned 3 grizzly products, all of which involved a motor and there were, whats the word im looking for...Crap, that it!
I sold my Grizzly knife grinder to a friend and when he turns it on he has to start the wheel spinning by hand to get it to run. I had that same problem with a Grizzly buffer. Not worth the trouble in my opinion.

Where would you guys put the Hardcore compared to the other high end grinders?
 
Fitz,

Just wanted to compare problems that you've found with the BM II...

1st: I'll say that I really like this machine...it has served me very well for at least 10 yrs, if not 12...Now to the things that bug me...;o)

1. Changing the drive wheel...to say that this could be easier is the understatement of the year...
2. Getting the platten or contact wheel straight/level so the belt tracks correctly...let's say I wish it were easier...
3. Found out that the motor was NOT GROUNDED when I got it and used it for nearly 8 yrs...fixed issue when I re-wired for 220v

Those are my top peeves about the grinder...

The good things:

Motor is impossible to stop...the Belt WILL break way before it slows the motor!!!
Good selection of accessories (I have a 4", 10", 1/2" contact wheels, the Flat Platten, Extender fork (for the 1/2") a 4" drive, a 8" Drive, plus flat rests for the FP and the Contact wheels) I'd like to find a slack belt attachment eventually...

So who else still has a BM II around?

Bruce
 
Oh yeah...forgot to post this link...I couldn't get much info from the seller but he thinks it either uses 2.5 x 60 or 72" belts...but anyhow the current price seems good particularly if you are closer to the chicago area...

Hi, Bruce,

I think you pretty much nailed it with the problems! Seriously, I think the only problem that affects me can be attributed to the design of the tracking mechanism and the fact the danged toolbars were round pegs. That's made proper indexing of the toolbars very difficult. (I've tried bubble levels and little pins and all sorts of tricks to make it set up easier. Change belts and everything changes.) That leads to the fact that unless they were right on, one had to compensate by shifting the toolbar with the tracking adjuctment. There is a point at which there is too much "off center" and the stability of the belt becomes a problem. Try and increase pressure to one side or the other of the platen grinding and the belt either flies off or grinds to a halt against the tension bar. :( That major deficiency was corrected on the B3 by going to a square toolbar.

The odd thing about B2's is that they either seemed to work great or more like mine in that respect. I know many people on both sides of the spectrum... go figure.

As for the drive wheel, if you get pissed enough to blast it with a CO2 fire extinguisher to chill the wheel, it comes off a little easier!! ;)

Truly, my complaints about the B2 center around the tracking. That grinder has stood me in good stead for many years. I wouldn't get rid of it, if that says anything.

I got a KMG, also, and really can't complain about it at all. Attachments can get a wee bit heavy with that large toolbar and a 14" wheel, but I think that's more me than the machine. I sure do like the tracking adjustment a lot better, where the idler moves and the wheel/platen is fixed.

BTW, Michael, the Hardcore is pretty much a copy of the old BurrKing, and sings the same praise! Great stuff if one likes a two-wheel machine. that design was the holy grail when I started this craft. To many it still is.
 
You guys hit the nail on the head with your comments about Bader tracking. My friend up the road has a BII and tracking is always an issue. I have a BIII and it is still finicky about tracking, especially with "X" weight belts. I have to keep the idler wheel crowned with electrical tape to get good tracking. With "J" flex or Norax belts it is not much of a problem. I think Bader needs to put a much higher crown on their idler wheels. They may have done so since I bought mine. I have one of the first BIII's made. I love the VS 2-hp motor though! :D

I played with a Hard Core down at Eugene a few years ago and it was smooth. I have used the Burr-King 960 and they are also a fine machine. The Bader is fabulous for quick tool changes and adjustments. However, I have come to the conclusion that a loaded KMG will be my next grinder. I think it incorporates much of the Bader flexibility with solid construction, great tool selection and superior tracking. Anyone have any experience with the Burr-King 1272? Engnath had a couple of them that he swore by.
 
I had a BIII and a BII. Just upgraded the BII to another BIII. One has the 2 h.p. motor and the new one I put on a 1 1/2 h.p. variable speed. Love both these machines. Also liked by BII but got tired of seperate tooling for the two machines. I bought my second BIII from Rob Frink. It was a demo machine he was using and was as new. It is nice to have two machines that use all the same accessories. I don't think the Bader is any better than the KMG, but they are equally both good machines. Just my .02.
