I drilled these out then we went out to the pub for dinner on returning I went out in my workshop to make up 2 rollerball pens and 2 fountain pens Well the fun began when the bushes wouldn't fit in the working end so still happy a little bit of reaming and away we go all turned ready to fit together first one the tail end just fell in then out none of the parts were a good fit second one same problems plus the two half's wouldn't screw together also one clips were bent so half a pot of ca job done and they do look good well sort of made with brown mallee and Yellow box burr with a polish finish
