I have made a few of these with luck I guess up to now that worked perfect, this time I turned the blank the thin blue line put one pen together and it won't click, (I did not press again the click button on the top) to install, it will push out slightly but won't retract and tried the second holding pressure on the refill (2nd. Pen not assembled) got no movement, wonder if I go a bad batch, woodcraft is where the come from, I sent them an email hope to hear from them Monday, will keep you all posted of the out come of that, has anyone had this issue, thanks.
