Thread: What can I do to lap 1/8" thickness off of a welch llyn medllyn

I have an old llyn medllyn home that has some deep scratches I would like to get rid of. I tried to use a hand held sander and it couldn't put a dent.. Is there maybe a local company that could get through it easier? Not sure if maybe a company with a smooth type of grinding wheel?

Have you tried some coarse SIC powder? It should eat 1/8" off of it pretty quickly.

Would I use it with maybe a DMT or use with sand paper?

You can use it on anything flat. I usually use the back side of my DMT for SIC. It won't get it perfectly flat but it's good for rapid removal to get past dishes or chips. Once you get past the deep scratches you can true it up on your DMT or W/D

I haven't used This before but it seems cheap and worth a shot.

It's good to have around if you buy a lot of vintage stones. I've never been able to get a stone perfectly flat using SIC (it's usually low on the edges for me) but it's good for grunt work.

That's exactly what I need. Grunt work. I never have a problem using w/d sand paper or DMT to clean up and lap my vintage stones but this one was at one point a slab of stone in someone's front yard with house number gouged into it. I want to rescue it because it is very large and fine.

Do not bother wit SIC or DMT get your self course linisher belt (about grit 60-80) Stick it on something flat and in few minutes it will be gone. Just remember yse a brush to de clog the belt and do not bother with water for the rough work (unles you can do it under running water). Once you get to the finer tuning then there is a place for water.

I remember that stone Mike, it's cool that you figured out what stone it is.

I bought a diamond disk for a fair price off ebay that rips through slate like butter, you can get them up to 24" then hook it up to a grain feeder reduction drive to electric motor, that is what I used. It sounds like you enjoy playing with stones, may as well get the tools you need.

The used gas powered concrete saws in 24" are a bargain in the pawn shops, I pick the one that will not start but have good strong compression, 135$ and you have a rough out saw, clean the carb and you are off to the races...

It was the green spots I see that gave away the origin of the stone. Now I just need to get it smooth and flat so I can use it. I should get the right tools for the job. Every time I say in done buying more I cme across more and can't help myself.
