the biggest foam routers I've seen were built something like an overhead crane with a gimbaled cutting head on an arm hanging down from the crane platform for something that size you might look into a cable drive setup something like the straight edge on an oversized drafting table and hang it from a couple of concrete walls in the garage or maybe build it up from sections of pallet rack as for the size of the components I'd think about breaking them down into more manageable chunks just to save on wasted foam you could easily get three or four half tubes to glue together out of a chunk of foam barely big enough to carve out one - one piece tube and it could be done on a much smaller machine Brian -- "Nemo me impune lacesset" ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
