   How do I do it?

   I want to bore a hole to accept a lav drain. You guys have seen those glass bowe

   Ha! a ceramic bowl that is. You get ceramic bowels from glass piggy banks maybe-

   So you have seen the glass bowls used for bath lavs?

   Eight or nine hundred bucks for the bowl- I can break a helluva lotta fifteen dollar bowls for that kinda money- any thoughts on how I can drill one?

   *You can get a speciality hole saw which will cut the hole. What it wont do is make you an overflow drain, which is what you pay thru the nose for on those fancy ones.

   *I've heard of it being done using a hole saw with carbide grit edges by carefuly cutting through the glazing on both sides. Once you get through that, cutting the clay underneath is easier. Having said that, don't most lav drains need the hole to have eased edges? Maybe you could make it a tad oversize to compensate. Oh yeah, are the $900 models made in a way that prevents them from breaking if someone drops something into them?

   *The specialty ceramic bits will work; however, the larger size are b expensive !Alternative:A length of brass tubing; put a dowel in one end so it can be chucked; using an ordinary hacksaw, cut across the diameter of the open end to about 1/4" deep; put some (depends on diameter) paste made out of rottonstone and mineral oil into the tube and start cutting your hole at low, very low, speed. One of those "drill guide" things (I have one that mounts between the chuck and the drill and has a base-plate like a router that tilts) will make this much easier.Overflow - drill smaller hole near the rim and bond a rt-angle fitting in there; for the drain, off-set a p-trap about a foot away from the tail then add a "dishwasher" drain adptor into the pipe between the tail and the p-trap; join the overflow and dishwasher fitting with a length of dishwasher drain hose.

   *Last year on a job the owner brought in several glass bowls to be used for bath lavs. They were to appear to 'float' (wall hung) above a polished granite countertop, also wall hung. No one would go near them because they were so expensive that no one wanted the blame...I think Phill is on to something. Why not just fill the bowl with an abrasive cutting medium which will only cut where pressure is applied, ie, under the brass rod/dowel? A fine grit would lap the hole as it goes.Oh yeah, those bowls the owner brought in didn't have an overflow. They looked like glass fruit bowls with a hole in the bottom.

   *Bowels they're not. It's a "vessel" you dunce.

   *If using an abrasive saw to cut, filling the bowl with water or seting up some sort or water spray will keep you from cracking the porcelin becasue of heat. Now there's lots of other waus tp crack one though.

   *Been there, had to use an acetylene torch to burn the holes and then melt/bend glass tubing into the structure for plumbing; it actually stood on the downpipe like a wine glass and was steadied by the overflow which went straight into the wall. The plug was a grey-water gate-valve like the ones they use on trailers and motorhomes hidden under the counter and operated by two door-lock solenoids. I hear that it was a maintenence/cleaning nightmare and that once all their friends had seen it, they completely remodeled the bathroom.
