Nah, they aren't ;)

Metric and imperial are never a direct replacement, they are always slightly bigger/smaller than the imperial size etc.

I got 1.2, 1.3 and 1.4mm from my LHS that does model trains and what not... 60p each.

[bigred5765]

Nah, they aren't ;)
there not if your anal enough to measure down to 0.001"and 0.0001

[Northy]

Or want to swap set-ups with other people...... :woot:

that should do the trick yeah?

Not exact, but it has useful increments in sizes from 0.3mm to 1.6mm
