Love it, that's a really nice pen and superb for a first go, not that I know much as not tried yet.

An obvious, probably stupid question following on from Melanie saying hers was a good fit using a 1/4 " drill. You didn't use a 6mm one did you? Often sold under the guise of 1/4" which it is not!

I have a number of 1/4" drills and they have a fair bit of tollerance when measured
