Thread: Your opinions please !!

I work at a coal fired power plant, and the pipes that feed the coal to the burners are lined with ceramic tiles. I got a hold of some used ones and thought of trying them out as a finishing hone. Your thought please. I have spent 5 hour lapping it with a DMT lapping plate, although not quite done yet, but it is a very hard surface. This tile has had millions of tons of coal running across it's surface, just to tell you how hard it is !!

interresting for sure and I'd love to hear wheter or not it works

I do think that these where produced in order to resist breaking but I don't think this entails they aimed for an homogeneuous grainsize in these tiles but who knows?

I like the way your brain is working. I want one

How does your DMT plate looks like after all that lapping?

Still looking very good, if anything I think it has helped it by smoothing out the courser areas.

I would expect nicely polished DMT.

5 hours of lapping a ceramic tile = No wife or girlfriend,,,,,

Just a crazy idea, but it could work who knows...

As the surgeon says, "Let's operate and see what happens!"

Of course Bituminous Coal is pretty soft stuff if they use Lignite it's even softer. Whether you tile works will depend on what it is made of. There's all kinds of ceramic.
