Anybody have a good relatively cheap means of sharpening knives

from rough to finish: grinder, belt sander, file, diamond stones, sand paper, sharpening stones, lapping paper or polishing compound

This link shows you how you can build something out of wood and a few other things. First you use a file on the guide rod to get the general bevel and then you move to free hand stones or long stones to fit on this, hell I bet you can make a wood block to attach wet/dry sand paper to if you don't have stones

I use a bench mounted belt sander with a waterproof belt. That's like $80 on harbor freight. It's been working for 5-6 years now I think.

If you're handy with a stick welder or better then the prospect of building a bombproof belt sander is within your grasp. There's plenty of tutorials online on building a 2x72 belt sander out of steel square tube and any higher power motor you can find.

I've built three of them. I'm on the third one and sold the other two for far more than I put into them.

Angle grinder and a flapper wheel.

Forge the shape of the edge and then set it with a file. There are also hand-cranked grinding wheels that are fairly cheap. You can rig them up with a foot pedal - check YouTube.

>knives and axes
apples and oranges

for an axe, just a file and rough stone

sandpaper and an angle grinder

This. Flap and paper disc abrasives are fucking wonderful. So are 6" cutting discs which is why I stopped buying 4.5" grinders. A 6" grinder will run smaller wheels of course.

Get hold of one of those hand crank bench grinders perhaps? One actually turned up today at the local "second hand shop but just for tools" and I may go and get it tomorrow if I can be bothered.

The guy asked for around £8, so is that 10 dollars?

I will post pics if I do get it.

Turn coffee cup upside down. Hey you got a ceramic sharpener! I guess you could use a bowl or plate for larger blades. As long as it's mostly flat it'll give a decent edge if you keep the angle consistent.

Why the waterproof belt?

>>1142436
To keep the blade cool. The metal wasn't annealed. If you anneal it then it doesn't matter. You can harden and temper it after sharpening. Once you've done that you'll need to use water cooling if you want to rework the edge or use a sander to simply sharpen it or whatever.

Like those "professional" knife sharpening places often times ruin the edge of the knife by using a belt sander that isn't water cooled. Of course that means the customer needs to return more often. Job security can be pretty evil.

you can grind on any rough stone. it'll just take longer than with a belt.

second for shaping before sharpening.

Also suggest a spray bottle filled with water, spritzing on belts/knife between applying the sandpaper to it will aid cooling drastically.
