The SS-70 surfacer/sander which was demonstrated at the Paul Bunyan show did an excellent job.It sure was a crowd pleaser and the slabs we surfaced sold as quickly as they were finished.This unit can plane and sand a slab in under an hour (both sides) ready for finishing.We did a whole stack of slabs at the show never taking more than 20 minutes per slab!This amazing machine put such a nice finish ...
