No mate I would have said if that was the case, I wouldn't want you wasting time init?
I think it is a great idea in principle the only things I see as a possible issue is batch changes and ill fitting tubes.
Like when they changed the diameter of the sierra without warning, it would need some maintaining to keep it somewhere near accurate.
Inaccurate, general guide or outdated I don't think is good enough.
By the time you have checked the database and found it to be wrong you might as well measure in the first place init?
Is it specifically drill sizes and or tube diameters cos you could continue and not know where to stop.
Someone could take it as a new bible and expect to see plating thickness etc, that's going over the top but you get my point.
I dare say it would work well for the Yanks cos they have specs for the manufacturers to produce to within tolerances.
But that don't gonna work over here cos we have to put up with the crap we are sold, we are at the mercy of the Chinks init?
Until we adjust our prices and demand quality our only constant is being at their mercy so to speak but that's another gripe.
