Trueing a wetstone

[ike]

The stone on my Rexon horizontal grinder is no longer flat. As I been (attempting) to flatten the backs of a new set of chisels, the stone's got progressively worse. I've resorted to a hand stone which I can keep flat with the aid of a sheet of toughened glass.

Whats the best way to bring the stone flat again?

Ike,

I don't know the grinder but can you dismount the wheel and re-true using the glass and abrasive method?

Ike,

Just remembered and had a look at the pistures Tony posted of his stones. If you haven't got a piece of glass big enough, then I'd use a piece of mdf and spray mount a number of abrasive sheets to it. Then all you have to do is rub it around to get it nice and flat.

I reckon that would work until you get the raised bit in the middle.

IIRC Tony's had sucess using a devil stone to dress the wheel, and I found a dimond stone not bad either. The devil stone's much cheaper though.

Cheers, Alf

Hhmmm...thinking aloud here. I'd seen the diamond trueing thingy on a stick on Axminster. Problem as I see it is not only is stone 'domed' slightly, the wear is uneven around the periphery - theres a real low spot. If I flatten it on glass, I'll get it flat but maybe not even thickness so it'll still undulate at the periphery. I could use the devil stone but same problem perhaps. But if I mounted the trueing 'device' on the sliding tool holder, I could get it flat and level guaranteed. Maybe adapt the diamond stick thingy i.e bend the handle so I can clamp it to the toolholder so it'll come down flat onto the stone (making the angle adjuster a height adjuster), or maybe I could true it back just by sharpening a planer blade (shame I haven't got a spare one that can be sacrificed).

Thanks all for the suggestions - any further input more than welcome.

Just wondering, but would mounting it onto a lathe and dressing the stone on there be a big no-no? :?

Edited because it would be pretty pointless as that is the same as dressing it whilst mounted on the unit itself.

Maybe a cheaper solution than using the diamond stick thingy clamped to the toolholder would be to stick wet n' dry to a piece of wood clamped to same. Worth trying but what grit paper is best for 1000 grit wetstone?

I used a DMT diamond stone for a while and it was great. I then purchased the devil stone from Axminster for about £4 and this works fine

I remove the tool rest and then simply hold the stone across the entire wheel as it spins

Ok, I'll give it a whirl. BTW. There was I steadfastly 'flattening' my chisels only to discover I was steadily making them more concave Still, managed to rescue victory from the jaws of defeat avec trusty hand stone.

ike tony's the man for advise on this piece of kit i think everything must be razor sharp and flat in his work shop after the workout he gave his rexon look for yourself https://www.ukworkshop.co.uk/forums/viewtopic.php?t=2501&highlight=rexon

thanks AP. I know he's been thrashing the poor thing (the Rexon that is) :shock :lol: : . I was thinking of alternatives cos I haven't got a trueing stone and sods law I put an order in to Axminster the day before this problem came up.
