Thanks guys...I'll give it another bash later with the suggestions posted up here.

Now off to watch those Videos!

PS Bill - point taken about leaving the key in the chuck! In my lame defence, it was late & I just wanted to get some rough & ready photos posted up here (the lathe wasn't even plugged in when the photos were taken!). As it goes my lathe has a chuckguard that is meant to close a safety switch when in position - problem is I got the lathe in a state of disrepair & the chuckguard switch mechanism was lying loose in a box - I can't for the life of me see how the switch can be closed by the chuckguard - so for the time being it's overridden...but I will pencil in a trip to one of the Axminster stores soon, to see if I can eyeball how the darned thing gets actuated by the chuckguard. I realise it's a golden rule & I'm actually paranod about it - far better to have a failsafe like a chuckguard switch which will protect my cheek from being embedded with the key (that said it might get me a couple more weeks off work)
