Newbie questions


I am wanting to purchase a grinder but don't have much money to spend and am considering the Grizzly. The question I have about it is if it is at all possible to hollow grind a blade with the stock grinder? Also is it possible to "cut" out a knife with a belt grinder instead of a bandsaw? And last but not least, is hardening a blade with a torch until red hot and checking it with a magnet then temering it by watching the colors on it at all acurate?

There are other threads on the forums here about the limitations of the stock Grizzly- check them out. If it's the most you can afford, yes, you can grind a blade from it.

I do all of my profiling with the grinder, and none with the band saw, which I only use for cutting stock to lenght.

If you are working with a basic tool steel like O1, you can indeed heat treat it with a torch. If you use any of the exotic stainless alloys like ATS34 or 440C, you can have them heat treated by experts for $5-10 per blade, which is a very good investment.

The grinder does 90% of the work for you.
It is my opinion that one should not skimp here esspesially.
Check out the TOOL TIME forum, there are Grizzly topics and regular grinder topics to help you learn more about each grinder.I have heard that grizzlys are good for the money.
I am still in love with my Burr King.

While I can't imagine life without my bandsaw, I do most all of the shaping with the grinder too.

Carbon steels can be cooked with a torch, but not the S/S's.

Note: The transformation temperature is slightly higher than non-magnetic. Heat it up a little higher than what makes the magnet fall,(just a few more seconds)and it should get you there.

I think I will go with the Grizzly beacause as all of you guys can remember, money at the age of 16 is rather scarce:-) Also where can i send blades to be heat treated?

Thanks,
Justin

They will heat treat and cryo treat your blades for a very reasonable price.

Other options are K&G in Arizona, or Paul Bos in California.

The Grizzly is on sale for $275 + $48 shipping if I'm not mistaken. I bought one a little while ago, I'm a newbie knifemaker as well. I think it's a pretty good machine for the price, and Grizzly customer service is fantastic. Platen bracket and platen wasn't quite right (wrong angle), and Grizzly sent me a new set quickly to replace it. The technician on the phone talked me through wheel re-alignment when my machine wasn't tracking right. It'll be really hard to hollow grind on this machine though. The motor gets in the way because it's direct drive when you do a lot of contact wheel grinding. You can do gradual transitions with a little practice by tracking the belt off the side of the platen. I'm still practicing my grinding. In the art of knifemaking, I'm not even tiny grasshopper yet.

Don't waste your money on the Grizzly sanding belts. The metal working belts are silicon carbide and for some reason, they cut really poorly (not too bad of a finish though). The aluminum oxide belts probably aren't as good of a value as the Carbo-Schroder belts sold elsewhere.

You can most most of your profiling on the grinder, and curves can be done by setting your workrest perpendicular to the platen and tracking the belt off the side and using the corners of the platen to get inside the curves.
