I'm very green at this, and just getting started tearing down a Burke No 4 Milling Machine. I'm having trouble removing the table. I presumed that I remove the gib and the table should pick right up, but the gib moves only about 1/2" before getting stuck either way. Before I go pounding on this hard, just want to confirm I'm doing this correctly. All gib screws are all the way out, and the table feed screw has been removed, so it's just the table and the gib stuck in place.
