Sink Holes....

[mrcaptainbob]

Picked up the 'specific' sink my wife wanted. Neat design made special for Lowe's. We picked up (and installed) shower faucet fixtures to match the sink fixtures we already had (and admired). Go to intall the sink fixture and find that the bezels for the handles won't fit on a 4" center sink. That's when I find that Lowe's can't order it, and that American Standard (who makes the sink) cannot get it in 8" as it's made for THEM in China! So, the bezels will fit with a small space between them if I 'drill' (enlarge?) the two outboard holes. Each side of the faucet would look similar to the double circles for MasterCard emblem, but would be covered by the handle bezels.
My question: What can I use to 'enlarge' the holes? A Dremel bit for tile? Some kind of diamond tipped bit? Carbide and water?

That's a bummer. What material is the sink made out of?

[mrcaptainbob]

Vitreous China. Six Carbide spiral flutes, three diamind bits, and about four hours and it's mission accomplished! The faucets set in place quite nicely, covering up the original holes as well, and the 'Sink-Chooser' is happy. And if She's (cap's on purpose...) happy, we're all happy!

Wow, and you didn't crack the china? Amazing! How did you do it, did you drill holes around the circumfrance and then use the flutes to remove the inbeteen? Good job

The handy-dnady-Dremel. I coverd the area with masking tape and drew out the centers for what was needed. Then centered the bezels and drew the rings from them. Razor cut out the centers, then used the small diamond to scar the porcelian at that point, just to ensure any cracks won't 'travel'. Then just started shaving with the carbides. When I got a feel for the fit of the faucet body, I ground the high spots with the diamond. THe brass threads leave a nice print on the high spots. Good tell-tales on where to peel away a bit more. THat's where the diamond bits came in handy. Yeah, We're pretty pleased with the way it came out. Sure is tiring on the wrists, though!
