Thread: Did I just screw up my thuri??

Hello all,
I decided to flatten my small thuri recently . I used my recently purchased Norton lapping stone (in set with 220/1k,4k/8K). The texture of the thuri was muuuuch different than prior to lapping (yes I lapped both sides) . I then moved to the 8K hoping no permanent damage had been done. While my thuri is definitely flat, it does not seem to be a smooth as it was. Have I put myself in the market for a new finisher ?

Thanks for all your input!

just smooth it further with 320 sand paper and you will be fine.
You can go higher if you feel like you want even smoother surface, but I think 320 will be enough.

No your fine, the Norton Lap stone is a 220 so it feels a bit rough

You want to use something in the 325-600 range, some people go even higher by personal preference...

You can use some wet-r-dry sandpaper on a flat surface to smooth it some,,, Just wet the surface place the sandpaper on it and lap gently...

Keep in mind that this is not absolutely neccesary....

Edit: As Stefen already said because he typed faster hehehe

Don't panic - you'll be OK. The Norton stone is just pretty coarse, is all. If you get some some quality wet and dry sandpaper and have a bit of thick sheet glass or flat marble or similar handy, use that to refinish the thuri. Puddle of water on the glass, paper pressed grit side up over the puddle, more water on paper and then rub the thuri on it. Its a softish stone so will cut quite quickly. Keep flushing the slurry away with water. Most people seem to go to around 325 grit, but 600 grit is good and I have gone up to 800 and more. If you are going to use a number of sheets, try something like 220/325/600/800

Regards,
Neil

drat - Stefan and Glen beat me to it - I'd hate to have a type-off with those guys...

Yes it is ruined beyond repair. Send it to me for safe and proper disposal.

Whew!! My thanks mainaman and gssixgun! This is great news. I'll pick up the paper this weekend and get back in business!

Much appreciated!

Ahhh Jimmy...such a great helper! Thank you for the offer, but I just could not bear the burden of sticking you with that awful stone.

I have found that the Naniwa 400 does a nice job with the finer naturals. I use it a lot.

I was told by a guy that really knows what he's talking about that the Norton 1K will do a real nice job of smoothing them out as well.

Remember this a stone not a waffle its a very tough critter, just try not to drop it because then it does not matter

If you do drop it after you're done crying it's time to see who needs Thuringan slurry stones.
