enlarging 3/4" hole to 1 1/2" in clay pot

[Don Morris]

Did pretty much what Floyd said to do with a 1 1/2" hole saw through some plywood that I attached to the pot. Went slow. took forever it seemed, but worked. Still, like the Rotozip idea with a ceramic bit. Bet that would have been faster. Maybe next time. Thanks to all for the ideas.

Do you have a 3/4 hole saw? You could maybe mount the 3/4 inside the 1 1/2 and use it to center the larger? Not sure if you can find one that little. Once started, remove the smaller.

I used this technique to enlarge a hole in a computer desk and it worked perfect.

Drill 3 more 3/4" holes to get the same area.

(0.75/2)^2 * 3.14 = .44 sq in.
(1.5/2)^2 * 3.14 = 1.76 sq in.

Better, drill 2 of them and let her try it before doing the 3rd so you don't have to ask us how to fill a hole in a clay pot.

Can we say say "Think ouside the box?!" Good one...

Indicate on the drill press and redrill a cheap test indicator will do for woodwork and is extremely handy. I brought one home on a whim and now its in my drill stand.
