Nicely finished off John;
I would just like to make a comment on the way you stop your keyless drill chuck; whilst we older members do things that we've become used to doing over the years I would ask you to reinforce the point of
NOT slowing the chuck down with your hand

There may be raw beginners in the ME forums who may consider this method as 'the norm' & there could be a beginner who does not have a keyless chuck & unthinkingly /unwittingly tries the method shown with a normal keyed chuck..(common sense does not always prevail), & yes, I too, have done this with both types of chuck so am also guilty as charged.. even when I was teaching apprentices years back, my caveat to them was 'do as I say, not as I do'. My two penn'orth said, as always a super video well shown & I look forward to your next one.
