An inexpensive way of finding a disk grinder for grinding blades is to look at your surplus houses around you . Buy a dc motoer and controller (used) and build it from there.
ALSO
Used dc gear reduction units that run at 200-300 rpm are great for this and many other uses in the shop. Just buy a controller with reverse and they can be used for the same purpose. A disk can be added to these for grinding.
The 110v units can be used for deburring , flattining stock (a mock surface grinder)
ect.
These units cost about 50 - 100 dollars around where I am when I find a good bargin and I buy them for the parts or to make other machines with.

Great idea Darrel!! Tim Herman even grinds his blades on a 9" disc. I'm fixin to make myself one for grinding folder blades. Take care! Michael

Hello,


Better yet and Cheaper too, is to just go to your local Tools supplyier and have them order you a Replacement DISK for one of there models and when you get it insert a Round steel Shaft into it about 4 inches long and then Chuck it up in your Drill press,, works great!!!!

when i was doing the ARTSY,Shiney type(not hardcore Using) type knives thats the way i did it,,,,,,,,works great ,,also bond a 1/8
inch 90 DUro piece of industrial rubber to the face of it,,,it helps on taking up vibration and produces a superior Finish.

And the best part is that the Grinding Disk bought this way is only about 14.00 for a 8 inch slightly higher for a 10 to 12 inch, and using it in the drill press gives you Variable speed(if your press is). Saves money, and if you get the technique right,,,a better finish that those high priced limited ability machines.

Dang i guess i will have to do another Video now!!!!!! 8-)

my .02 for what its worth.

Darrel, Allen and others....I've become more and more intrigued with disk grinding blades. I've read the posts and absorbed them, but I'm a bit of a "visual" person. If you folks could take a few pics with close-ups of your disk grinders and post them to the forum, I, for one, would be grateful. I personally would like to see a close-up of how the disk attaches to the motor arbor as well as how the motor attaches to your bench/table. Many thanks for the great info. you all share so willingly......mucho appreciado!!!
