Hello, Rowdy,
Thanks for the pic, matey! Well, now I'm stuffed! Here's you and Ed using the same tool, and with confidence, yet when I had a tentative go with mine the bloody tip snapped in half. I could understand if I was rough with it but, nope, I wasn't. Ah well, maybe it was a flaw in the metal? I will have a go with the remaining tip, but this time will start with less of it protruding from the holder. Watch this space, guys (and listen for the screams)!!!
Many thanks to everyone who contributed to this thread - it's much appreciated!
Bob.
