It was stuck tight and the only way to get it out was to unscrew it. Anyhow the screw gun im using (Automatic feed type) needs dismantling to use reverse. I managed to get it apart with one hand but forgot to put it in reverse and screwed my finger on even tighter. that really hurt. anyhow apart from blood all over the concrete at work I'm ok.
Thank you for sharing .......that was very funny on my end. I just told Marion as she wanted to know what I was laughing at and she thought is was pretty funny too.
