Truing up an oil stone

So, I have an old (like borrowed from Dad 40 years ago old) Indian oil stone.
It doesnt have a distinct dip or anything, but feels pretty uneven when putting a knife over it.

Any tips for getting the surface back to square/flat?

put in vice and sharpen your axe/slasher/machete by using the whole stone you will even it out.

How about a carbide block - i got one to square up my bench grinder wheels. About 10cm long and 2 cm square.

If you can't see the dip i wouldn't worry about it for another 40years

A sheet of 240 grit wet and dry on a flat surface, glass pane etc. Lubricate with Kerosene or similar. circular motions or figure of eight, not back and forwards. Check with a straight edge.

Yep, wet and dry on glass

:thumbsup:

And if its full of shitty oil you can gently boil it in a shallow pot ( old pot ) of water with something under it so that its not on the bottom and leave it there for ages and the oil will slowly come out.

Because generally why aren't intended to be used with oil !
Water is just fine for most stones
Oil is a lubricant and therefore not the ideal medium for grinding

we always used the dish detergent at home 40ish years ago....still do it today,it worked so havent seen need to change.

Or put it on a flat diamond wheel with water which will do the job.

I stole the stone from the old boy, and he always used fine grade oil. I just followed on with that :(

CRC on stone is what I use at home and work.

Have always done mine like this or on a flat piece of concrete.

Soak your stone in a strong solution of Simple Green for a couple of weeks, then boil it, and repeat a couple of times to remove the old oil. Then use a squirter bottle with Simple Green in it for lub when sharpening. You will be amazed at how much faster your stones will cut

If you have a really flat piece of concrete you can rub the stone on that, that will take the surface off.
If you clean it up, get rid of the oil, dishwashing solution (you’re soaking in it if you are old enough to remember that), then it’s easy to wash and remove the oil filings after use.
