Thread: Coticule no flat

I am furious. I have received coticule of Howard, solicits that it flattened it. It has come without flattening. There is a difference of but of 1mm between the center and the ends . as I can solve it?

Thanks for your aid

Have you emailed Howard since you've received it? That would be the first thing I'd do.

If you want to flatten it yourself, there's plenty of information here on the forums, just do a search for flattening or lapping and you should get plenty of advice.

yeah, i was gonna get one too from howard but I was going to the the diamond plate so I can flatten it when needed.

Slight cupping is not too bad. I never lap my hones. My Escher has at least 1 mm and still works great. You could get a lapping stone or use a piece of window pane cover it with sandpaper and flatten away! You may want to use fairly coarse sandpaper first but finish with at least 400 grit sandpaper.

Don't worry too much Estroncio. Kees' advice is excellent. You can solve the problem in 20 minutes with some sandpaper and a flat marble or glass tile.

Thanks for your advice. Today I am badly. They have taken one hour in taking note in a restaurant, I have cut the finger, have spilled a coffee on my clothes… I hope that the bad luck finishes fast
