Hi, just reading through the manual cant help noticing that the clearances on the guide blocks differ hugely! Is this a miss print? the 255 has a clearance of 2-5 thou but the 204 is 2-1/2 a thou is this right as the metric conversion printed doesn't add up??:eek:

Hi.
Just which manual are you refering to?

You are correct both are not the same for imperial but similar for metric. Or am I to reading incorrectly/
