I too had problems right out of the gate with the table elevation mechanism. I had read the unfavorable reviews but decided to buy anyway based upon Fine Wookworking's favorable review.My machine was improperly set up right out of the box. I spend several very frustrating hours taking the machine apart, properly setting up the indexing belt and adjusting the table mechanism.Once I got everything corrected it works great, but for what I paid, it is extremely frustrating to have to spend hours correcting what was to have been "factory assembled and adjusted".
