How To Repair Old Stone Grinder Whetstone

it is no longer level.

It's worth mentioning right at the get-go that a stone that is curved along its length is nonetheless usable every bit-is.

Honing stones/whetstones don't accept to be flat to provide a suitable sharpening surface for all tasks. Certain honing or whetting jobs do crave a flat surface (e.g. working on the unbeveled side of most woodworking tools, which generally need to remain expressionless flat) but honing the bevels of whatever tool, including knives, chisels and plane irons, can effectively be done on a curved surface.

This is precisely why many old stones are found greatly hollowed or 'dished' in the centre in the outset identify — they continued to be used over time subsequently condign worn in the eye from utilise, and the hollow just becomes deeper and deeper over time.

should I just get a new one?

Assuming you can't use the stone as information technology is, totally up to yous.

Be aware if you do want to flatten it the type of stone it is makes a massive deviation in how hands flattening can exist done.

Sure natural stones traditionally used with oil, and many artificial oilstones, are very hard indeed then they are resistant to abrasion to say the least. This is a great thing as far every bit use goes, because they tend to dish very very slowly in use (and if used carefully non really at all, even over many decades), simply this is not your friend if y'all desire to dress such a stone dorsum to flat.

On the other hand certain natural stones traditionally used with water, and many artificial waterstones, are quite soft to very soft and these are very easy to re-flatten. Which is good equally they need it often, sometimes daily, fifty-fifty with normal amounts of use.

Obviously in addition to the hardness or toughness of the stone the corporeality of dishing is a big gene:

The stone on the left here would probably crave a great deal more than piece of work to put right than the one on the right!

So in summary, the labour necessary to get the rock back to flat might be considerable, or information technology might be not much at all.

is in that location a mode to level a whetstone again?

Your rock sounds like it's dished on both faces but worth noting for future searchers that every stone has ii faces and two sides, and it'southward very uncommon to see all iii of the other long surfaces of a stone dished in addition to the arbitrary top face. Sometimes simply flipping a stone over can requite the owner a flat surface with no endeavor expended! If both faces are dished as sometimes seen the long sides tin can be used if necessary.

If you practise want or need to flatten yous can utilize a broad range of abrasives, or abrasive surfaces, to wearing apparel or lap the surface of whetstones.

A non-inclusive list of things people have used include:

• the back of ceramic tiles
• the flat side of quondam grindstones
• a flattish spot on a concrete surface (pavement, driveway, fifty-fifty a wall)
• the side of a physical block
• a brick
• another whetstone
• abrasive powder^one and water, commonly on a glass or rock surface
• abrasive papers, films and cloths
• diamond plates
• diamond pulverization, suspension or paste on a metal plate
• belt sanders²

The process mostly is just to rub the stone back and forth, sometimes in circles, until the loftier spots have been worn off and the stone has become flat over again. Sometimes this is done dry, sometimes using water to affluent abroad waste.

Apparently this goes much more speedily if the abrasive existence used is very hard and coarse, so for this reason if your stone is a harder type and you take much fabric to remove I would recommend you utilise coarse silicon carbide pulverization (80 dust or coarser).

Merely that said you tin do the piece of work on concrete if yous have to. I've washed information technology myself a couple of times and while it takes a long time it does somewhen get the job done.

¹ Usually silicon carbide, merely even sand can piece of work albeit much more slowly.

² Be extremely careful of the dust generated if you endeavour to flatten any type of rock, but specially natural stones, with a belt sander. Some stones comprise silica and fine silica particles are very hazardous to breathe in.
