I was at a small demonstration recently.
I was the person who drummed up the pen turning whilst a colleague turned a couple of Corian slim lines.
Everything was going well, pens coming from him, I assembled and displayed the finished pens.
He decided to finish with an olive wood slim line.
Turning down was going well, until, "snap", I started to waffle about grain and tool catches until I saw his red face.
He had picked a pair of blanks that he hadn't glued any brass tubes in
Good luck Derek I hope everything goes well for you.
