How to mark centre of 12mm hole

[gros21]

Well I know it's a basicly a horrible description. But I have 12mm holes and I need to line this up mm perfect and mark another piece before drilling it out.

Any ideas.

depending what your holes are already in, use a cover plate.

as in if holes are on flat timber, tape a thin piece ply over both holes and mark out on it.

The easiest method to transfer dowel positions is to use "dowel markers" or "dowel marking points."

but I'm sure if you search around you will find 12mm versions on the 'net.

If you have one to hand, a 12mm forstner bit will do in a pinch... provided they're not stopped holes.
