bench grinder

I would like to have a sharp knife all the time. I was wondering if anybody ever used a 1500 grit disc bolted to the side of the stone on their bench grinder. That way you could just touch the knife against the side to achieve an edge

Grinding wheel is meant to be pinched a certain way and what you are suggesting in my opinion is dangerous.Try a sharpener system where you have two stones held up or jigs that keep the angles.There was a pretty good discussion on sharpening a few weeks ago.

The disc is just paper fiber would it affect it that much?

dr sportster · Dec 19, 2014

Under the washer for the wheels there should be a paper gasket. But I am not a machinist and I'm sure you will get more comments . The guys that could shave the arm hair when I was in the Marines used two white round sticks of stone in a holder that kept tha angle. You could put a flat disc in the drill press and do what you want to do safer. I just dont think you should mess with the side of the grinding wheels.Thats just me.

wouldnt want to be around if the stone let go ! and also,that might get hot and ruen the tempering of the blade . There are lots of knife sharpeners out there at all prices anywhere from a few bucks for a whet stome,to hundereds of $$ for water wheel systems. personally the lanskey and a leather strop with jewelers rouge on it work for me,that and a good 2 sided arkansas whet stone ,but thats just me...
you could ask a hundered different people and get as many different answers ,kind of "feel " thing

Thanks guys: I guess I will just continue to use a whetstone then 1500 grit sand paper. I have never ran into a rabbit that needed shaved. :wink:

It works to use the wheel. Have to be really
careful how much pressure to put on the blade. It
will disappear in a second. Don't ask how I know
that.

Davyfireball: personally, I'd stay away from using anything attached to the stone, if for no other reason than it would seem to me to be difficult to keep it tight and running true. What I've done is just took an old motor I got cheap and attached an old drill chuck to it. I then cut several 6" disks out of a piece of MDF I'd scrounged from an old cabinet or somesuch, put a 1/4" flat-head screw through them countersunk below the surface with a nut on the back side to hold it tight, and attached various grits of paper with spray adhesive to them. I can then chuck them up and they work dandy for sharpening and polishing. I can post pictures if you're interested, but the video I linked below is to a quite similar setup except I don't have the buffing wheel attachment on mine. It also works well for drilling, rasping, sanding, burnishing, and a number of other uses.

Stepped out to the garage for something so snapped a picture while I was there.

Some things you talk about and don't do, and some things you do and don't talk about.

I use my belt sander.

You can get 1500 grit for a DA sander that is self stick. We have to have razor sharp knives to trim thin soft flash on plastic wheels/parts. For right handed people I have them or do it for the operators flatten one side and keep the angle on the other side. With the blade away from you and the sharp edge down the flat side would be on the right for right handed people and the left side flat for left handed people. I only allow Barlow knives to be used for trimming. I just use a fine stone to work on the edge and then strop the edge on cardboard to keep it razor sharp after getting them flat on a course stone.
