The Huge Blocks on this page are called Box Blocks and they continue in the
same scale as our school sized unit blocks but extend into the next
increments of size. Lumber does not come in an infinity of sizes.
It is dried as planks in a kiln, and the largest common thickness is
typically 2" (called 'eight quarter'). Instead of making
larger blocks as a single piece (which would be too heavy anyway) we
extend the range of size by making boxes (open ended). Thus we have a set of
boxes that are 2-3/4 by 2-3/4 in cross section by a variety of lengths -
and these correspond in the regular unit blocks to square columns or
pillars. Next we have boxes that are 2-3/4 by 5-1/2 in cross section by a variety of
lengths and these correspond to very large unit blocks . . . .and so on
up to our humongous box that is 5-1/2 by 11 by 22".
These boxes are all amply strong enough to stand on (including
elephants), but users should be
cautioned to watch out for large assemblages because just like regular
blocks, they can all fall down and someone could get injured climbing on
them. These are American Hard Maple and are for indoor use only unless painted.
