Thread: Gutted...

Well, I've just learnt one thing about lapping hones. Dont let them slip out of your wet hands over a metal sink.

I was just lapping my brand new set of Shaptons and I managed to knock the 8000 on the side of the aforementioned sink and the glass shattered. That stupid mistake cost me $75 for a new one...

I've tried to re-lap it but its bowed slightly and you can hear the glass moving (read crunching slightly) when its being lapped, and I'm not prepared to chance it with a razor. Besides which, I dont want a brand new set of hones with one of them broken just coz I'm a muppet.

I'm absolutely gutted, I was really looking forward to dragging out my restore project this weekend and giving it a hone.... And I'm really p*ssed off at myself for making such a stupid error.

Sorry to hear that. Not nearly as bad, or expensive as your story, but my first lapping experience resulted in a "V" shaped valley in the middle of my 8000K Norton. I didn't reread the documentation and ended up using a small DMT, trying to speed things up. It took one to two minutes to damage the hone and hours to correct. Not to mention at least 1/4 of the 8000K side is gone from the hone.

Its easy done i've bumped the corner and took chips out. have you got the holder i watched howard lap is shaptons leaving them on the holder then rinsing them with pump acton spray

Thanks guys, I guess this is how we live and learn... Still doesnt make me feel any better about it though..!

The others were fine, this wasnt even the first one I did. I'd done the 1k and 4k already and they were fine, not a single hiccup. I did the 16k afterwards as well and that was fine too... I guess its just one of those stupid things we do when we're learning something new..!

I'll just make sure I`m ultra ultra careful with them all and when I get my new 8k I'll rest the DMT in the bottom of the sink so I cant drop anything..!

As they say, experience is the name everyone gives to their mistakes!

Condolences for your loss from the other side of the pond.

Do not throw out that 8k. Provided the ceramic side has not cracked, you can bond the entire 8k, cracked tempered glass and all to a piece of marble tile or similarly rigid and flat material. Bond it with epoxy. THEN lap it. No worries.

I've done this successfully with a Shapton 1k ceramic on glass stone after I purposely rip cut the stone in half using a diamond wet saw.
