Re: [CAD_CAM_EDM_DRO] Re: measuring scales and thermal compensation

Hi Jon,

I stand corrected, in fact the more I thought about it I realised that there
were flaws in my arguement. I suppose ideas like this come with lack of
experience - heating of parts being machined is the least of my worries in
watchmaking and as to accurate measurements - I just don't do 'em. For me to
measure the parts I make would be prohibitively expensive and a waste of
time - I just make 'em to fit!
