Hi all,
I did use the measure of 30 and 7/32nds, with gives us 767,55625 millimeters,
and rounded them up to 768mm. This is indeed a bit too much, because we got also
problems with bridges (96 studs long) mounted on a table 30 bricks below the
zero level (zero level = 75 cm above ground level). The piles from the bridge
where bend (broken) due to this problem. I just placed 4 gray base plates of
48*48 studs in line, fixed with 2*4 plates, and measured the distance between
the two middle base plates. This gives me 767mm. I guess that this would be
better than using 768mm. Additional problems are humidity (we use MDF sheets),
cutting and mounting tolerance and the tolerance on the LEGO bricks. As stated
in the following tread: http://news.lugnet.com/lego/?n=2139&t=i&v=a is abouth
6%.
B.T.W: My first tables where build after the original drawings of Ben Fleskes (4
tables of 3x3 and 4 tables of 3x6).
Note also the adition of extra holes for extended use of different sizes of
tables (1x1, 1x2,1x3) : www.brickshelf.com/cgi-bin/gallery.cgi?f=82078
Pictures of the use of those special pieces will be posted as soon as possible.
