I have noticed how well you are settling down to 'precision' engineering.

Thanks for noticing John, I am trying....very, some would say.....!!

Very nice rescue Darren.
Now you have learned about 'feel'.
By using my tapping stand, I tapped about 30 10BA threads last week in a job (1.4mm tapping drill), and not one of them felt as if it was going to break.
Below about 5mm you really do need that 'feel'. With larger sizes you can usually get away with it.
They are available for reasonable prices in the market place, but I have heard that sometimes you can get the odd one made by a cross eyed Chinaman with no arms.

Very good Darren.
Another trick I've learned is that you hold on the round part of the tap not on the little square part at the top. If the drill is small I just hand tighten the tap in the chuck. If it gets stuck it will spin in the chuck.

after a trip to Bogs Towwers and saw what Mr Bogs uses ,I have Just bought one of the ARC tapping stands and it's ok . the problem was I thought it was going to be a bit bigger that it is, but that is not a problem as it will do everything I will want it to do, I was hopping to use the base to set out on but its a bit small.
Chronos do one as well if you are in no rush to tap holes this year.
