In the past, I have heard that the tolerance for bricks is .02mm (From
Henry Wiencek’s The World of LEGO Toys and other sources).

That’s nothing. My
“Ultimate Lego Book” (Foreword by KKK himself) tells me that in 1963 ABS
allowed moulding precision to 0.005 mm (0.0002 inches).

I’ve got yet another doc (not sure of the source-- was emailed to me as an
Offical ‘standard Lego FAQ’ sorta thing) that reports:
“The precision molds are made at two LEGO factories in Germany and
Switzerland. They are precise to five-thousandths of a millimeter.”
So, I assume they mean five thousandths (0.05mm)
|
I think you mean 0.005? (ie the same as the ULB above). Anyhow, the precision
of molds may not be the same as moulding precision?

instead of 1/5000th of a mm
(0.0002mm). Of course ‘one five-thousandth of a meter’ would match the 0.2mm
that Jake reported. Sounds like it’s possibly something that’s gotten
misinterpreted in language a few times rather than in digits, since spelling
it out can get rather confusing :)
