It looks nice and I am a bit envious ;- ) For the feed dog drop, I would just keep on using some type of spray can stuff on the parts involved from knob to feed dogs, then turn to a good oil. I know you know all about it. On the freearm models the feed dog drop is a small turn button on under or to the right of the stitch width knob. There should be black, flat metal piece connecting the setting button to the feed dogs, the joints involved needs to be detected. I think the knob on the flat be version turns from six o'clock to either three o'clock or some where inbetween 3 and 6.
