Greasing control mechanism on 1926 Singer
 

The manual for my 1926 Singer 99-13 says to "occasionally lubricate the bearing points of the controller mechanism." This is in addition to applying grease to the little silver tubes right on the motor. Of course there are no pictures for this... I've got the controller mechanism open (which is cool, I've never been brave enough to lift that little lid!), but I'll be darned if I know where I'm supposed to apply the grease... This is the thing that the knee control lever hooks into. Thanks for any ideas!
