My friend was here for 2 days and she brought her elderly FW with her, its about a 1936.
The lady she bought it from said that her engineer son had cleaned and oiled it. OMG The only thing he did was glop lots of black grease on the top & bottom gears. He didn't clean out the lint or oil anything, he did tighten all the screws and the handwheel clutch way too much and used a screw driver that was too big. grrrr! Some people should never be allowed to "service" a sewing machine ever!! :x I'd never serviced a FW that had no grease left in the motor at all.
I gave the sweet FW lots of TLC and she sews very well now; purrs just like she should.
