Hi all I also got a 99K in a cabinet recently, Have oiled, cleaned, and polished and it sews fine. My question is...is there a place that I am supposed to "grease" this machine with Singer lube grease from a tube, or is just oiling in the spots shown in the manual enough. Thanks for all your help...I have read all I can find on this machine....I think it found me, instead of me finding it. I have a featherweight and love it...will the attachments work on both machines?? The 99K is a 1956. The featherweight is a 1936... both low shank... with lots of attachments.
