Hi Mark, so long as you got out of it what you expected to get out of it, then it was all worth while, and you learned a few lesson on the way. Nothing wrong with the pen or the finish in the end. Well done mate.
Very good, Mark!!! I like that you had all the processes in place to make the pen. There ain't no stopping you now!
PS. It may already be mentioned but that break-out you had might be caused by not making sure that the CA was spread evenly along the tube - if its "floating" there will be no support against the chisel, and the loose bit will fly off! But you knew that already, right?
Bob.
