Hole location for Herbie for overflow's

BRS also recommended using a dremel and smoothing out a bit and stood by the measruements that it should work. So I pulled the old dremel out and in less than a minute each I was able to get the 1 " bulkheads into the 42 (now probably 43 mm holes. Yay success! Thanks everyone.

Awesome! What kind of bit did you use?

I had a similar problem when I drilled my nanocube. The hole was maybe 0.8mm too small to fit the bulkhead completely in.

Used a dremel bit just like this (see below), and went to town. I ran the tool around the hole, against the rotation direction of the bit .... and kept just going around and around quickly. I can be done dry, and it only took about 5 minutes per hole to get a perfect fit.

I didnt use that one (didnt have it.) I cant find a picture of the bit I used but it is basically a rod that tapers to a point with the diamond on the outside of about a cm of the tapering portion. So I basically moved the side of the rod in a circular fashion on the inside of the hole.
