tools for that pesky feed dog plate screw.
On many of my Singers and others, the back screw holding the feed dog cover is hard to reach.
I will often reach for my offset screwdriver or my Swiss Army knife with the big screwdriver blade half out. They are a bit awkward to use, but can get a grip when other options don't work..
I use the cut off skewer for moving stuck slides if I've already tried oil and wiggles.[ATTACH=CONFIG]593758[/ATTACH]
