Yup, i finally convinced my parents to let me spend the money on a real grinder instead of trying to build my own grinder. it is on backorder, so i will get in in mid to late Sept, but I am going to be at college till early Oct, so i will have my machinist friend put it together and try it out. What should I have him look for concerning QC??? Also, what belts should I buy??? I am looking for something for a good price, but that will last long, as my parents wont let me spend much $$$ on belts and steel. I am going to get some more O-1 and 1095 to learn on and then get 440C, and A-2 or D-2 for my real blades! I cant wait till i am home for breaks and can grind!
 
If you are getting the 1095 just to practice your grinding and then throw away the blades, go to a hardware store and pick up some mild steel. You can practice all you want on that and it is real cheap. Then buy some good blade steel and make knives out of 'em. You can't harden the mild steel but it is a cheap way of practicing grinding.

I already know how to grind out blades, Crayola. 4 from 0-1, 2 from A-2 and like 4 or 5 from 1095. Hopefully pics of my first 2 sold are going to be here soon! 1095 is easy to grind and can make a decent knife that I can sell hopefully and make some money to pay off the grinder and mistakes arent too expensive! I jsut want to get used to hollow grinding and flat grinding, but make a knife i can sell for 40 or maybe even $50 to help pay for the grinder. Good using knife, not the prettiest, but I am still learning!

AAhhh grasshopper, you are learning. But not everyone follows the same road or has the same budjet.
How goes the knot knife????

I am not familier with the grizzly but if it has the jam start with 36 or 40 grit then go 80-120-220-400-600-800-1000-1500-etc to whatever finish you desire wether done on the grinder or hand finished.
You may have a tough time getting a good finish with the grizzly with your hollow gringing because to my knowledge it is not a variable speed machine.

Hope you have better luck getting your grinder than I am having getting my milling machine. I ordered it on June 6 and it still isn't here (10 weeks???). If I hadn't heard good things about it from a friend that has one, I'd probably have cancelled the order by now (the price was right, also). Why is it so hard for Grizzly to ship things on time???

at least they haven't charged me for it, yet.....

taz how much is this grizzly thing costing and is it a 2x72?.............. laurence wwwrhinoknives.com
 
Taz, there is some imformation on the quality of the Grizzly in the archive. Most of it was about a contac wheel being out of true. Mine had some side to side play of the idler wheel. The stepped down portion of the
idler wheel axle was a little long.( Quick fix though.)I haven't done any grinding on it yet, but it is very smooth and the belts track well. I'm sorry to hear that some members have had poor results with Grizzly Ind. In my dealings with them, they have been very prompt and proffessional. Take care.
 
Taz,

With a few mods the Grizzly will work pretty well. My only complaint is that it is not variable speed.

1. If your contact wheel is not true and out of balance, send it back. Tell them to send a good one and check it before shipping. Their customer service is good, IMO.
2. The L-bracket which supports the idler adjustment knob is weak. Put some shims behind it to eliminate play.
3. The platen will not be flat. For a quick fix, bend and/or hammer it flat and hand sand it on a sanding block. The better alternative is to replace it with a piece of hardened steel. Also consider radiusing the edges of the platen.
4. The rest that comes with it is junk (might make good practice material...lol). I fabricated my own rest out of some angle iron and plate steel. It attaches to the platen support bracket. When yours arrives, let me know and I will walk you through it if you are interested. It helps to have a visual.
5. I had Rob Frink make me a 4" drive wheel. It really helps when doing the finish grinding (if flat grinding).

Opinions vary on which belts to buy, so I will tell you what works for me and why. I use 3M ceramics (60, 120, and 220) and Trizacts. Norton Hoggers (60 and 120) from Tru-grit are also good. I just bought some 967 belts that are supposed to work well at slower speeds. I have not had much chance to evaluate them, though. In my experience, AO and SC cut slower, run hotter, and wear out faster. Even though the belts I use are more expensive, I am saving money.
I just recently started buying from James Poplin of Pop Knives. He has better prices than others I have found who sell these belts. His number is (706) 678-5408 (call between 4-8 pm eastern).
