While my industrial Conover (about a 1963 model) is great for upholstery, leather, bags, etc. you can not FMQ with it--it's a heavy duty engine that you literally have to press the foot pedal slightly to be able to lift the presser foot--that disengages the clutch. Mine is old enough that you can't drop the feed dogs and the continual walking foot prevents FMQ. But the Stovall, MO quilting company uses several industrial machines (Conovers and Singers) that are similar and an overhead system of tracks that hold up the quilt and these quilters are amazing--they FMQ at lightening speed as they are moving the quilts back and forth.
