I am retired now.  I do a little leatherwork.  I own a SInger 42-5 machine.  I have a little experience in Care and Feeding of it.  I found Bobbins on Ebay here:https://www.ebay.com/itm/14535-Shuttle-Bobbins-FIT-FOR-SINGER-11-11-11-33-42-4-42-5-42-8-SEWING/153747883042?hash=item23cc168422:g:FuIAAOSwwJ1d5cp0

recently, but the center hole is too big to use your standard bobbin winder.  However with a cordless drill and a 3/16 flat head screwdriver bit you can wind a bobbin in about 30 sec

Just replaced the clutch motor with a servo motor...Made the machine much more controllable.  Not sure I need to get a speed reducer.  It has slowed down a lot.
