Sounds a bit like my wife when she goes shopping never checks the cupboards first and walks round thinking I better get 2 of these. When I unpack for her I say but you already have 4 of these. Oh well never mind.

Mich been there cap, T Shirt and lots of spares in the workshop, even ended up with 2 rotary tables at one point I got carried away at a club auction.

Michael,

Worth bearing in mind that ISO metric taps are always over nominal size, by design. Don't think this is generally true of imperial taps though.

Hi David, what's the thinking about oversize metric taps by design?
